[U-Boot-Users] Problems with EP862
Does anyone have U-Boot up and running on an Embedded Planet EP862 board?
I have U-Boot 0.4.0 working with SDRAM and Flash, but when I compile it to read the environment variables from the EEPROM, it won't boot. Does anyone have this working?
I can however get it to boot if I compile it to get its environment variables from flash (it just complains and then loads some defaults).
Thanks in advance, Jeff Stevens Software Engineer Systran Corporation

Is your I2C driver working? Try the i2c and eeprom commands to verify this first...

Yes, the eeprom command works fine. Here is the screen dump. I then altered the code to print out the data and it printed the env settings for the PlanetCore boot loader that comes with the board.
=> eeprom read 0x54 0x00 10
EEPROM @0x54 read: addr 00000054 off 0000 count 16 ... done

I don't understand. Why did you have to modify code?
The standard commands
=> eeprom read <addr> <off> <len> => md <addr>
will do the job. What is the problem?
=> eeprom read 0x54 0x00 10

Well, if EEPROM accesses work, you just have to configur your board correctly .
