Hi.
I have a board which I am using Uboot on. Arm9, nand flash, etc.
Currently the board has the uboot image and the ENV in one partition, size 0x00200000.
I would like to make another partition for the ENV so that if I have to upgrade Uboot I don't lose my ENV.
What size does the partition have to be?
And where in the Uboot code do I change the memory location and size for the env so I can rebuild Uboot and start using a new ENV partition?
I have eldk set up on my Linux VM and have received our current Uboot project modded for our target. I have successfully built a duplicate of and re-flashed the Uboot I'm currently running on my target card so I know I'm good to go as far as building and deploying.
Another side question is about FW_print/set/saveenv. We are running Linux on this board and would like to mod the ENV from Linux for network config changes? Is this the best way to do it? I'm assuming once I know where my ENV lives I would just put that in the config file for FW_printenv.
Hopefully my questions are not too rudimentary.
Regards,
Michael Galime
