[U-Boot] Compilation error for fw_printenv
Hi All,
While trying to compile fw_printenv under tools/env directory of u-boot i am getting the following error:
fw_env.c:34:27: error: linux/mtd/mtd.h: No such file or directory fw_env.c: In function fw_printenv: fw_env.c: In function flash_io: fw_env.c:390: error: erase_info_t undeclared (first use in this function) fw_env.c:390: error: (Each undeclared identifier is reported only once fw_env.c:390: error: for each function it appears in.) fw_env.c:390: error: expected before erase fw_env.c:421: error: erase undeclared (first use in this function) fw_env.c:423: error: MEMUNLOCK undeclared (first use in this function) fw_env.c:462: error: MEMERASE undeclared (first use in this function) fw_env.c:519: error: MEMLOCK undeclared (first use in this function) make: *** [fw_printenv] Error 1
How can i solve this? I a very new to Linux Environment.
Thanks Rahanesh

Obviously your cross tool chain does not provide the (needed) linux/mtd/mtd.h header file. Either use a more complete tool chain (we use the ELDK), or manually add this file to your cross tool chain's headers.

Dear Wolfgang.
Obviously your cross tool chain does not provide the (needed) linux/mtd/mtd.h header file. Either use a more complete tool chain (we use the ELDK), or manually add this file to your cross tool chain's headers.
After cross compiling now i get the following behaviour. After issuing a fw_printenv it said * Bad data CRC, Using default environment... *and printed out few environment variables.* * Then i did a *fw_setenv bootdelay 6*. It showed some messgaes of erasing flash. But it actually erased my uboot itself.
What might be the issue? Any issue with the config file?
MTD device name Device offset Env. size Flash sector size Number of sectors /dev/mtd0 0x0000 0x1000 0x10000
What does Device Offset mean?
/dev/mtd0 has both uboot as well as environment variables. Environment variables lie at bottom of /dev/mtd0. Is that the meaning of device offset?
#define CFG_ENV_ADDR 0xAD03F000 (Flash starts at 0xAD000000) #define CFG_ENV_SIZE 0x1000 #define CFG_ENV_SECT_SIZE 0x10000
These are the macros that i found in include/configs/board.h
Please help
Thanks Rahanesh
