[U-Boot-Users] AT91SAM9260-EK: Trying to load U-Boot env from NAND

[Destrukto <simon.bielmann@gmx.ch>]

Yes! I get it work, the problem was, that it had a problem to accept the
crc32-Checksum. So I just erased the sequence where this happens. Here the
patchfile:

@@ -247,13 +247,7 @@ void env_relocate_spec (void)

-		return use_default();
-	else if(crc1_ok && !crc2_ok)
-		gd->env_valid = 1;
-	else if(!crc1_ok && crc2_ok)
-		gd->env_valid = 2;
-	else {

 		/* both ok - check serial */
 		if(tmp_env1->flags == 255 && tmp_env2->flags == 0)
 			gd->env_valid = 2;

 	if(gd->env_valid == 1) {
 		env_ptr = tmp_env1;

Maybe it isn't the best solution but it works ;)
Thanks for you help!!
