The DM9K is connected on the CS4 (like the mini2440). I already had troubles with the ethernet, and we applied (as suggested here) the DM900 errata consisting in gating IOR & CS. The DM9000 is working better now, but when I write some file on the NAND Flash, the DM900 is reseting (link down, link up). Reading from NAND flash is fine. If I put the whole rootfs in the SD card, I have no problems. Here the schematics of the DM9000 and how it's plugged on the CPU : http://people.apache.org/~jvermillard/atsarm9/ Any suggestion ?
