[U-Boot-Users] Question about Bad CRC

[Rugunda, Solo]

Wolfgang, 

1. I think I might be making an error with the syntax. Can you verify
that this is the exact correct syntax to fix the Bad CRC (quotations,
colons etc)
(or am I making an error somewhere in the syntax)

#define CONFIG_PREEBOOT "setenv preboot 'setenv preboot;saveenv';"


2. And also can you verify that I would add this line in the file that I
am adding this line of code to is at91rm9200dk.h in
/u-boot/include/configs

Thanks a lot

If you don't have access to the  console,  you  won;t  even  see  the
warning  message,  so  just ignore it and continue to use the default
environment. Where's the problem?

You can do tricks like defining a CONFIG_PREBOOT command equivalent to
this one:

	=> setenv preboot 'setenv preboot;saveenv'

At the time of the next boot this will first delete this setting (so
it's run exactly once only), and then save the environment.
