I have an Cortex A8 based development board, I would like to setup a simple OS, for example to connect through SSH to the board and upload/write new program(blink led etc). The board comes with a CD which is contains the Linux kernel,
make zImage
I followed this tutorial, this is for Android, but I don't want a GUI.
After the compilation what am I supposed to do, I would like to have almost the same functionality as Ubuntu server.
What I am supposed to copy to the SD card?
ARM boards often use the U-Boot bootloader, and the Linux kernel in uImage files rather than zImage. You really do not need to use
ssh
if you have a secure network. I usetelnet
since the LAN consists of just the PC and the ARM board with a switch (using static IP addresses.) – sawdust – 2012-07-12T09:18:36.520If you don't want a GUI, then you don't need a new kernel. Simply inhibit the start of the X server during init (the exact procedure to do this depends on the startup mechanism, but usually involves rc scripts). But maybe you have misstated what you want. Do you really want a shell in a terminal on the VGA/LCD display, OR did you really want a headless configuration with the console on the serial port, /dev/tty ? That may require a new kernel build, or at least a new kernel command line. – sawdust – 2012-07-13T09:10:50.957
