Hi All,
I have a u-boot version for Davinci 6446 and would like to access r/w the
u-boot environment from linux userpace.
I set the /etc/fw_env.config to /dev/mtd0 0
0x4000 0x200
When I execute fw_printenv, I got these error:
Warning: Bad CRC, using default environment
But, when I commented out the memcpy on the condition below, I could be able
to display my uboot environment.
Although, there were few enviroment variables where the values are corrupted
or missing few characters.
if (!crc1_ok) {
fprintf (stderr,
"Warning: Bad CRC, using default environment\n");
/*memcpy(environment.data, default_environment, sizeof
default_environment);*/
}
Any one can give me a hints on how to fix it?
Thanks,
John
