U-Boot : 'make' problem

Max,

Great to hear things are working :-)

> Is the warning important, what CRC is it about ?

u-boot maintains environment variables in a flash sector. The default

for the Altera Cyclone devkit is at 0x0002_0000 (3rd sector).

When u-boot starts up it attempts to read the environment variables from

this sector ... but runs a 32-bit CRC to ensure integrity. To get rid of the

warning you can simply issue the 'saveenv' command.

BUT BE CAREFUL ... if you already have something else saved in that sector,

(like uClinux) ... you might want to re-configure the environment address

(include/configs/PK1C20.c -- see the CFG_ENV_ADDR macro).

Best Regards,
