In one of my devices, uboot-environment is located at a bad block. "save Saving Environment to NAND... Erasing Nand... Skipping bad block at 0x000c0000
Writing to Nand... FAILED!"
In my memory mapping I have already reseverd 2blocks. How can I setup uboot in a way, that it will look at c0000 or (in case of bad block) at the next block e0000?
In my configs file I found somewhat like: #define CONFIG_ENV_SIZE (128 << 10) /* 128 KiB */ #define SMNAND_ENV_OFFSET 0xC0000 /* environment starts here */ #define CONFIG_SYS_ENV_SECT_SIZE boot_flash_sec
in mem.c of my processor I found: f_sec = (128 << 10); /* 128 KiB */ /* env setup */ boot_flash_base = base; boot_flash_off = f_off; boot_flash_sec = f_sec;
uboot is based on 2010.03 release.
Maybe someone can give me an advice? Thanks - Arno
PS: Move the base address of environment is not an option, as in next device the bad block might be on exact this location. Environment itself is just 2kB, but a block is 128k. Can I decrease the environment to that size and still use access from linux (via fw_printenv)?
