      How do you dump the env vriables to a file via the BDI? and is there a way to
re-download them the board?
Thanks

Doing a setenv and saveenv write the variables to the eeprom. Erasing th
eflash via the BDI does not reset those variables. Is there a way to erase
the eeprom from the BDI.
Thanks for the replies.

I usually change the environment variables with setenv, saveenv and
printenv commands, and dump them to a file using the BDI2000 for
backup.  If later on I need to restore those environment variables, I
just write the backup file back to the target flash.
I don't think the BDI2000 is capable of changing the environment
variables in flash memory with just one command.

I don't exactly understand what you are trying to do. Can you please
explain more clearly? If you have BDI2000 connected you can use it to
re-image the board I think - why to change bootcmd?
Anyway to change bootcmd you probably will need to re-burn entire u-boot
environment: it has CRC and rewriting just one variable. It's possible
based on u-boot sources write program which take as an input text
script, generating u-boot environment, and makes binary image out of it
which can be burned to u-boot environment area.

Hi,
Does anyone know if it is possible to set and env variable through the
BDI2000 or set the bootcmd via the BDI2000?
I am trying to download an image to an ppc board and want to be able to
re-image the board by changing the bootcmd via the BDI programmer.
Thanks
