We didn't have problems until recent changes in the board. Now we have a problem with u-boot loading.
We are using your M5485BFEE boards with Linux BPS m547x_8x_evb_20080811-final-ltib.iso, CF Flasher 3.1.9 and U-boot.
Everything was ok untill tou made some changes in board's design and flash memory.
Now attempt to write U-boot into EEPROM failes.
Steps to reproduce:

1. Flash U-boot 1.3.3. with CF Flasher 3.1.9. On CF Flasher's address request 0xff800000 is entered.
2. Re-power board. Everything looks ok.
3. Optional: add new variable(s)
4. Enter command 'saveenv'
5. Reboot the board

See result on steps 4 and 5 below. How to fix it?
