I tried using a different distribution (debian) but the rest of my application did not work. I've tried opkg install mysql-client and opkg install mysql-server however I get the error Unknown package for both.

I'm trying to build a Linux Device Driver for a Devkit 8000. I'm getting the following errormessage: When I try to follow it's directions I get asked a bunch of yes/no questions I don't really understand. In the end, I get to choose between 25 different processors(?): Here's my makefile: ifeq ($(KERNELRELEASE),) KERNELDIR = ~/sources/linux-3.2.6 PWD := $(shell pwd) modules: $(MAKE) ARCH=arm CROSS_COMPILE=arm-angstrom-linux-gnueabi- -C $(KERNELDIR) M=$(PWD) modules .PHONY: modules clean else # called from kernel build system: just declare what our modules are obj-m := LED_timer.o endif I don't think my code itself is relevant yet, plus I **know** that my sourcecode is riddled with bugs, you don't want to see that, haha.

I have an Angstrom Linux device acting as an access point, running hostapd, dhcpd, which works fine. Can I get a list of devices connected to the Wi-Fi? I know I can get the DHCP leases, but I need to know which devices connect through wlan0. I've tried this (iwlist has options): iwlist wlan0 ap iwlist wlan0 accesspoints iwlist wlan0 peers but all return: wlan0 Interface doesn't have a list of Peers/Access-Points iwconfig, iwgetid, iwpriv and iwspy are also present in /sbin, but don't seem to have options to display the client list.

As said above, when I try to SSH into my embedded system (a De0-Nano-SoC FPGA development board running Angström with Kernel 4.1) I get a "Write Failed: Broken Pipe"-Error and get disconnected. I read that this is often linked to network problems and timeouts, but in my case it's happening instantly, so it can't be a timeout-issue (can it?). I'm searching for other solutions to this problem or other problems that might cause this error message. Update: The other direction (SSH from embedded to host PC) works flawlessly! Here's the output from tcpdump | grep cyclone5, juggernaut is the host PC, cyclone5 the embedded device and fritz.box is my router: 16:56:01.080879 IP6 juggernaut.fritz.box.48641 > fritz.box.domain: 3129+ A? cyclone5.

I'm trying to boot my BeagleBone Black into Angstrom using pre-built images found here . My SD card has two partitions BOOT & ROOTFS, and was formatted according to the procedures found here . Below are the contents of both partitions: The lost+found folder was the result of formatting the SD card and I haven't been able to delete it. I don't think this would cause u-boot to hang. However when booting, u-boot repeatedly tells me that it can't find /boot/uImage & /boot/am335x-boneblack.dtb: The first of the following 2 images is my uEnv.txt, it uses load mmc 0:2 to both load these files. The second image is the result after attempting to use ext4load mmc 0:2 since the ROOTFS partition is formatted as ext4: The ROOTFS (mmc 0:2) partition contains the rootfile system, but when I attempt to list the contents of the /boot directory u-boot returns nothing. When I had the SD card plugged into my comp and mounted. I attempted to ls the /boot directory and denied permission despite using sudo. Why can't uboot locate the uImage and dtb files?

I have written a bash script to automate cross-compiling an OpenCV program: echo "Compiling started for: $1" if [[ $1 == *.c ]] then gcc -ggdb pkg-config --cflags opencv -o basename $1 .c $1 pkg-config --libs opencv; elif [[ $1 == *.cpp ]] then g++ -ggdb pkg-config --cflags opencv -o basename $1 .cpp $1 pkg-config --libs opencv; else echo "Only c or c++ files" fi echo "Output: ${1%.*}" But now I noticed that there does not exist a bashrc at the Angstrom distribution. So what can I do?

I am working on a Colibri module having Angstrom linux installed in it! The processor is ARM v7. I am having trouble updating the softwares installed in the system. Whenever I tried the command opkg update, I'd get a bunch of errors. Probably, it seems that the support from Angstrom project has been withdrawn as it gives 404 content not found error.

Again, surprisingly, the error message is unbelievable... $ opkg install gcc Unknown package 'gcc'. Collected errors: * opkg_install_cmd: Cannot install package gcc. I have no idea as to how to resolve this error as it is completely surprising. Also, it is of immense importance as I have to complete it within 2 days of installing gcc and running C programs...

The aim is to build and install the USB Video Class (UVC) module, via make modules_install. I'm trying to configure the kernel via make menuconfig on Angstrom distribution, running on BeagleBoard-xM. Angstrom image (console only) was build on Narcissus online image builder. Angstrom kernel is 2.6.32. I receive the following error: make: *** No rule to make target 'menuconfig'. Stop. It seems that there are no kernel sources because usr/src contains nothing. Should I have to download Linux kernel 2.6.32 from kernel.org and what should be my next steps in order to configure the kernel?

I am using chipsee LCD + beaglebone black and Logitech Webcam C270. I am using the Angstrom OS distribution provided by Chipsee. I wanted to use Cheese to see if the webcam works fine or not.

I 'm running Angstrom distribution (console only) on BeagleBoard-xM. Image was build on Narcissus, with Bootloader Files (x-load/u-boot/scripts) added. I want to connect a USB webcam (Logitech Pro 9000). Problem is that device isn't recognised by the kernel (/dev/video0 not listed). I have some questions: 1. Is Video4Linux the driver I 'm looking for? 2. Should I had include a toolchain on Narcissus, in order to build Video4Linux, before installing it? (any installation guide would really be appreciated). 3. Is there any way instead, to rebuild Angstrom image including the appropriate drivers? Any help, would be really appreciated.

I am trying to tune the UDP receive and transmit buffer size. According to my real time application needs, I need to configure the Tx buffer as 6 bytes and Rx buffer as 22 bytes. I am running Angstrom on a ARM A9 processor. (Altera cyclone v soc). The client and server are communicating over WiFi in adhoc mode. root@cyclone5:/proc/sys/net/core# cat rmem_max 163840 root@cyclone5:/proc/sys/net/core# sysctl -w rmem_max=22 sysctl: cannot stat /proc/sys/rmem_max: No such file or directory The file is located at the path /proc/sys/net/core , however the stat is looking for the file at path /proc/sys/ I have also tried the following : root@cyclone5:/proc/sys/net/core# sysctl -w net.core.rmem_max=22 sysctl: setting key "net.core.rmem_max": Invalid argument net.core.rmem_max = 22 Does anyone have a hand on this problem? The purpose of tuning the buffer sizes is because, I do not want to queue up the packets in the buffers. It is ok to overwrite the old packet with new packets, every time the call to recvfrom and sendto is made. Edit: A little more debugging to this issue, I found out that the minimum bytes I can set to this buffer is 2240 bytes. root@cyclone5:/proc/sys/net/core# echo 2238 > rmem_max -sh: echo: write error: Invalid argument root@cyclone5:/proc/sys/net/core# echo 2239 > rmem_max -sh: echo: write error: Invalid argument root@cyclone5:/proc/sys/net/core# echo 2240 > rmem_max root@cyclone5:/proc/sys/net/core# cat rmem_max 2240 Is there anyway to reduce this number, to as low as 22 bytes ?

I have a small ARM board with Linux (Angström, kernel 4.1) and have connected it to a HDMI display. It works at the moment. I would like to show a splashscreen during the whole startup but it seems to be impossible. I use an init.d script with the fbi utility to display a picture but it's shown only for 3-4 seconds in the middle of startup. I have analyzed bootup sequence and found that the graphical mode was switched many times during the startup. I have an HDMI display with a 1024x600 resolution. The bootup sequence is attached. You can see the following switches: - 0.21 s - 720x576 - 0.37, 1.37 s - 640x480 - 1.42 s - 640x480 1.87 s - 640x480 - 2.22 s - 1024x600 (the right one! The splashscreen is probably displayed after that action) - 9 - 14s - 6 (!) times the same resolution 1024x600, what should it mean? I start the kernel from Uboot with the following command: mxc_hdmi.only_cea=0 video=mxcfb0:dev=hdmi,1024x600M@60,if=RGB24 And the picture was shown just for ca. 3-4 seconds after 2 seconds, so there is something wrong between the 7th second and the 9th second, no switching was here but also no picture on the screen. How should I fix it and let the picture in the screen for the full duration of the startup routine? Why does the system switch the resolutions so many times during startup? The GUI of the system is LXDE. Bootup log

OPKG is used as the package manager in an embedded Linux system. I would like to be able to determine the license of a package prior to installing the package. Is there a simple way to achieve this through the package manager (or related utility included with the Angstrom distribution)? Alternatively, can the package manager list the license(s) of an installed package?

I want to use DAS U-boot and a form of embedded Linux. Is bootloader code linked in any way to other source code (e.g. statically, dynamically)? Or is it standalone?

I'm trying to get a LAMP stack running on my BeagleBone Black, but I'm getting foiled early: opkg can't seem to find the apache2 package. According to the Angstrom page, it should exist: http://www.angstrom-distribution.org/repo/ (search "apache" for confirmation) ...but when I run opkg, it can't find it. This is what I see: root@beaglebone:~# opkg install apache2 Unknown package 'apache2'. Collected errors: * opkg_install_cmd: Cannot install package apache2. root@beaglebone:~# opkg list | grep apache2 php-fpm-apache2 - 5.3.19-r4.0.1 - php version 5.3.19-r4.0 ...and naturally, that's after running opkg update.

My provider script looks like this: debug logfile /home/logs/pppd.log user "vodafone" connect "/usr/sbin/chat -v -f /home/scripts/chatscripts/pap" /dev/ttyUSB_utps_modem 115200 noipdefault usepeerdns defaultroute persist noauth I have a script that is checking whether ping to ntdp server works, and if not it kills pppd and makes a new call (I am not sure if this is the correct way for something like that and maybe that makes problem): #!/bin/bash source /home/scripts/isconnected TTY="$(cat /home/scripts/.gsm_plugged)" SERVER="0.de.pool.ntp.org" sed s/isconnected=[0-9]/isconnected=0/ -i /home/scripts/isconnected while [ -c $TTY ] do sleep 30 ping -c 10 $SERVER > /dev/null if [ $? -ne 0 ] ; then echo "ping failed" echo "restarting" pkill pppd sleep 2 /usr/sbin/pppd call provider sleep 10 ntpdate -s 0.de.pool.ntp.org sed s/isconnected=[0-9]/isconnected=0/ -i /home/scripts/isconnected else sed s/isconnected=[0-9]/isconnected=1/ -i /home/scripts/isconnected fi done

I'm using a Beaglebone Black running the Angstrom v2012.12 build that came pre-loaded. I want to be able to connect another device to a serial port via the UART connections on the GPIO headers. The problem is I can't tell which /dev/tty devices these map to. When I try to access the /dev/ttyS? devices (e.g. using od /dev/ttyS2) I get a "read error: Input/output error". Can anyone tell me if the UARTS are mapped to tty devices by default, if so, which ones and if not how I can create the right devices?

I 'm running Angstrom distribution (console only) on BeagleBoard-xM. Image was build on Narcissus , with Bootloader Files (x-load/u-boot/scripts) added. I noticed that usr/src directory is empty. I intend to install kernel source packages. For this reason, I downloaded Linux kernel 2.6.32 from https://www.kernel.org . What should be my next steps? I 've been searching for days, but I didn't find anything. Any help would really be appreciated.

On my Beaglebone card I run Angstrom Linux. It has one cable in the ethernet port (etho) and a USB 3G modem dongle in the USB port whose interface is named wwan0. At the other end of the crossover ethernet cable is another Linux computer running on Raspberry Pi. When the ethernet cable is disconnected, I have internet access, but when the cable is attached, internet traffic gets directed on the eth0 interface. The ip route table looks like this: root@beaglebone:~# ip route default dev eth0 scope link default via 95.192.114.29 dev wwan0 95.192.114.28/30 dev wwan0 proto kernel scope link src 95.192.114.30 169.254.0.0/16 dev eth0 proto kernel scope link src 169.254.29.204 When doing ping 8.8.8.8 this fails, but when I do ping -I wwan0 8.8.8.8 This works fine. I can also ping ping 169.254.1.N # 'far' end of ethernet crossover cable which is the other end of the ethernet crossover cable and it works. So how do I make sure that internet traffic goes out on the right interface? Is this one of the cases where the "Advanced router" option must be selected in menuconfig before recompiling the kernel? Or is it enough to swap the order between the two default routes? This card doesn't route any data coming from somewhere else, it receives data on an I2C bus and is supposed to write this data to one server on the internet and another server on the other end of the crossover cable. /etc/network/interfaces iface eth0 inet static address 169.254.1.N+1 # 'near' end of crossover cable netmask 255.255.0.0 gateway 169.254.1.2 allow-hotplug wwan0 iface wwan0 inet dhcp Another issue which might be related is that the IP address isn't correctly set to the static one I set in /etc/network/interfaces above, it's on the correct subnet 169.254.0.X but it isn't what I statically configured. EDIT 4 ------ If I try to delete the default route under EDIT 2 route del default gw 0.0.0.0 dev eth0 connman jumps into action and immediately re-adds it again, as visible via journalctl: beaglebone connmand: eth0 {del} route 0.0.0.0 gw 0.0.0.0 scope 0 beaglebone connmand: eth0 {add} route 0.0.0.0 gw 0.0.0.0 scope 0 (the timestamps of those two lines are identical as viewed with journalctl --follow) EDIT 3 ------ root@beaglebone:~# ip a 1: lo: mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo 2: can0: mtu 16 qdisc pfifo_fast state UNKNOWN qlen 10 link/can 3: eth0: mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 34:b1:f7:1b:02:86 brd ff:ff:ff:ff:ff:ff inet 169.254.252.60/16 brd 169.254.255.255 scope global eth0 4: wwan0: mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 1000 link/ether 00:01:02:03:04:05 brd ff:ff:ff:ff:ff:ff inet 78.78.88.67/29 scope global wwan0 EDIT 2 ------ In my opinion the first row looks suspicious. netstat -rn Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 eth0 0.0.0.0 95.196.157.233 0.0.0.0 UG 0 0 0 wwan0 95.196.157.232 0.0.0.0 255.255.255.252 U 0 0 0 wwan0 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0 EDIT 0 & EDIT 1 --------------- As per comment by FloHimself below, the only subnet involved is 169.254.0.0/16 and one beginning with 192 is a typo. However, changing the static IP address doesn't keep the static IP from changing and the ping -I wwan0 is still the only way to reach the world wide web.

I am using Ångström Linux on BeagleBoard-xM . I have installed a RTL8188SU USB Wi-Fi adapter and configured it properly. But it doesn't connect automatically even though I have marked the interface as auto in /etc/network/interfaces file. My /etc/network/interfaces file is seen below (only wlan0 settings pasted): auto wlan0 iface wlan0 inet static address 192.168.2.50 netmask 255.255.255.0 gateway 192.168.2.1 wireless_mode managed wireless_essid MY NETWORK ESSID wireless_key MY_PASS And here is the output of ifconfig command after system boot: root@beagleboard:~# ifconfig lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:24 errors:0 dropped:0 overruns:0 frame:0 TX packets:24 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:1632 (1.5 KiB) TX bytes:1632 (1.5 KiB) wlan0 Link encap:Ethernet HWaddr XX:XX:XX:XX:XX:XX inet6 addr: fe80::2e0:4cff:fe03:cbb1/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:241 errors:0 dropped:0 overruns:0 frame:0 TX packets:6 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) As you can see, there is no inet connection on interface wlan0. When I type ifdown wlan0 and ifup wlan0 consecutively, the wireless connection can be established successfully according to interface settings. The output of ifconfig after restarting wlan0 is shown below: wlan0 Link encap:Ethernet HWaddr XX:XX:XX:XX:XX:XX inet addr:192.168.2.50 Bcast:192.168.2.255 Mask:255.255.255.0 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:974 errors:0 dropped:0 overruns:0 frame:0 TX packets:22 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) I want my wireless connection to be established automatically on system boot (and preferably after replugging Wi-Fi adapter). Is there anything that I am missing to do so? **EDIT:** I have traced boot log and seen a message that is complaining about setting ESSID: Error for wireless request "Set ESSID" (8B1A) : SET failed on device wlan0 ; Operation not permitted. However, I haven't realized the source of the problem. After the system boot I can establish connection by restarting networking.
