Hi Pedro,

Yes, indeed. It looks like the "bootm fc0c0000 - fd800000" is not
evaluated properly. In v1.3.1 code the code lines were
(common/cmd_bootm.c:622)
#if defined(CONFIG_OF_FLAT_TREE) || defined(CONFIG_OF_LIBFDT)
/* Look for a '-' which indicates to ignore the ramdisk argument
*/
if (argc >= 3 && strcmp(argv[2], "-") == 0) {
debug ("Skipping initrd\n");
len = data = 0;
}
else
#endif
So The upstream v1.3.1 config for TQM5200 also has CONFIG_OF_LIBFDT
defined:
$ git-show v1.3.1:include/configs/TQM5200.h | grep CONFIG_OF_LIBFDT
#define CONFIG_OF_LIBFDT 1
So if you did not change that, my last explanation is that you have
hidden escape characters in the definition of bootcmd_flash. Check with
'md' on the environment sectors to find out.
Cheers
Detlev
