Hello does someone succesful use linux 3.5 on the SPEAR320? ST offers a git repository with kernel 3.5. I'm able to compile it, but the configuration looks a bit strange and it does not run. I just want to know if it works. -- mit freundlichen Gr??en Heinz-J?rgen Oertel

Hello friends, I am working on a project which has the short term goal of porting Monta Vista Embedded Linux on a Intel PXA board (having ARM core). I am facing the problem at the initial stage itself. I have installed the Monta vista Linux on Windows platform. When i try to do make oldconfig (as per the kernel build guide) it shows the warning /bin/sh: line 1: xscale_le-gcc:...

I've been stopped dead by a limitation with the ARM-9 250 MHz SBCs, running Linux, that I've been relying on for my next project. The maximum rate I can run a repeat timer (setitimer, etc) at is 50Hz, ie. 20000 uS repeat time. If I set the repeat rate any faster the thing still repeats every 20mS. Is this a standard 'feature' of Linux SBCs? Does anyone run an SBC that will do significantl...

we are using arm-linux for development. Our reference board offer a way to boot linux using ramdisk with compressed filesystem. I don't know whether it would be written or not? would it applicapable for us to write data in to the .gz file?

Dear all, I want to transplant the programs to embeded linux on S3C2410 arm platform,but the original filesystem have no "usb/lp0" node,so I make a node using: #mknod /dev/usb/lp0 c 180 0 In kernel config I set "usb printer" option on,so how can I opration the printer? just use open,write? how can I know the commands to drive the printer? I'm not sure there's drivers in linux k...

I am looking a low power (less than 5watt), small embedded Linux board to be carried on a model airplane. Linux box must have * Flash Disk (64-128MB) * 128-256MB memory * at least 3 serial ports (RS232) * a parallel printer port (to be used as digital I/O) * a wireless LAN (optional) Can anybody help with this ?

Has anyone ever tried to port Linux or uCLinux to a modern PLC? Interested to see if it can be done. Thanks, Fred

Maybe this question should be posted in a linux development group, however the use of a serial port is more typical in an embedded environment, so I try to post here. I have an embedded Linux box (based on a Raspberry) with a serial port converted to a USB port through a UART-USB transceiver from Microchip. This USB port is seen as a COM port under Windows OS. I need to do simple ope...

Hi all, I've a FOX Board (Linux Embedded) with RS485 port, and a Power Counter (RS485 too) that work at 9600E1. With a USB to RS485 cable and windows i can successfully communicate with the Counter, writing a simple c# application. The rs485 linux board work too (with others devices). I can't read always correctly between the linux board and the counter, and i don't know why. I've analyzed wi...

I have a Linux-based SOM that intregrates complexity (CPU, memories, Ethernet PHY and so on) and I'm going to design a carrier board for it. I'd like to add an external watchdog on the carrier board for two purposes: - automatically rerun the system when the applications running on Linux crash for some reasons (mainly bugs) - automatically rerun the system when the system is not able to...

I am looking for some reliable statistics about embedded systems, generally concerning operating systems. Some paper showing the percentage of embedded systems running Linux, BSD, WinCE, ... Maybe there is something showing what linux distributions are preferred on linux embedded systems, showing uclinux etc. Any help is gladly appreciated. Thank you very much in advance! Mike

Hi, All. In my Linux program I need to have a simple command line input and use telnet as command console. I try to use Linux readline library. It works when I use standard input and output. When I open socket, associate file "dirstream" with it and make redirections: rl_instream = dirstream; rl_outstream = dirstream; the readline outputs prompt to remote telnet console, but I ca...

The AT91SAM9260 appears to include EBI support for CompactFlash, but the AT91SAM9260-EK development board does not include a CompactFlash interface. Assuming I can come up with the hardware, how hard will it be to develop the U-Boot and Linux driver support required to boot Linux 2.6 from CompactFlash on the AT91SAM9260? Is this driver code already out there somewhere? Thanks. Jim ...

linuxval means linux virtual abstract layer. By this , people can port ucos-ii , freertos , etc. to linuxbox easily. In linuxval SingleThread version, all tasks use one thread together and tasks can switch in this thread by linux *context functions. RTOS can look at linux as a spcecial machine by linuxval. Now,linuxval can support task context switches and has a time interrupt. linuxval makes i...

hi, guys we have ported linux on STMP36XX. Untill now we implement a serial console on Application UART, MTD driver for nand, TD018 LCD driver. Using initrd or jiffs2 on nandflash we could boot linux to prompt on serial console. we also implement a simple framebuffer driver to display on LCD. With miniGUI, a sample bomb program could show on the LCD. for absence of input device on LCD, We...
