Hi, Im trying to nand-boot TI 2430SDP.
What i do is to flash nand boot NOR U-BOOT# nand erase 0x10000 0x40000 NOR U-BOOT# tftpboot 0x80000000 u-boot.bin NOR U-BOOT# nand write.jffs2 0x80000000 0x22444
I am able to get u-boot prompt; But, i aslo get the message: ## Error: environment overflow, "stdin" deleted ## Error: environment overflow, "stdout" deleted ## Error: environment overflow, "stderr" deleted
when i do printenv - it printfs some vague characters and lots of blank spaces. Environment size: 131069/131068 bytes im not able to save any environment - since it detects that the environment space is full,
I also tried erasing the environment space too - but the result is the same. Im dont get vague characters, abcedf.... and lots of spaces. ( blank lines)
I know - to start with, the space reserved for the environment is occupied.
How do i come out of this situation.
Also, does u-boot save some default environment variables, if so, where should i look?.
my board/omap2430sdp.c does not saveenv.
But for this to occur, i think there should be some free space left to save my envs.
How is this handled for the very "first" time - boards just out of factory?.
Please advice,
Regards, sriram
