* Bootloader & Flash @ 2007-11-07 12:00 schardt 2007-11-07 20:39 ` MingLiu 0 siblings, 1 reply; 7+ messages in thread From: schardt @ 2007-11-07 12:00 UTC (permalink / raw) To: Linuxppc-embedded Hi, i use the AVnet Xilinx4 FX12 Minimodule and until now, i use system-ace to configure the fpga and boot the linux kernel. But now, i want to boot from the on board flash memory and have no idea where to start. I think i have to: - save the fpga configuration in the fpga-prom - use/program some kind of bootloader store in fpga block ram to jump to the flash-adress where the executable linux kernel resist - use the mtd-device driver to mount root fs on the same flash some address later Is this the right way ?

What I have done is to put it in the CF card or via NFS. But I guess with MTD driver's support, it will not be difficult to do that. Good luck.
