[U-Boot] fw_printenv (uboot2011.12) 'Warning: Bad CRC, using default environment'

[Andy Neubi]

hi,
i'm using the uboot-tools (fw_printenv) to readout the env-settings of my beagleboard-XM uboot. unfortunately i always getthe 'Warning: Bad CRC, using default environment' msg
[root at buildroot ~]# cat /proc/mtd dev:    size   erasesize  namemtd0: 00080000 00020000 "X-Loader"mtd1: 001e0000 00020000 "U-Boot"mtd2: 00020000 00020000 "U-Boot Env"mtd3: 00800000 00020000 "Kernel"mtd4: 00800000 00020000 "Kernel Backup Partition"mtd5: 0ed80000 00020000 "File System"

[root at buildroot ~]# fw_printenv Warning: Bad CRC, using default environmentbootcmd=bootp; setenv bootargs root=/dev/nfs nfsroot=${serverip}:${rootpath} ip=${ipaddr}:${serverip}:${gatewayip}:${netmask}:${hostname}::off; bootmbootdelay=5baudrate=115200

- uboot-version of my beagleboard is 2013.04- uboot-tools-version under buildroot is 2011.12- ubuntu 13.04

Q: what i'm doing wrong?




-> IMHO so in most cases 2 different uboot versions are not good, so i tried to build the uboot-tools-2013.04 ... unfortunately i always get

Q: ... i tried to modify the Makefile but without any success - somehow the includepath is wrong?!



Q: what is wrong with my "fw_printenv" setting?Q: why can't i build the uboot-tools later than uboot-2011.12 (all newer versions are broken)

cheers for any suggestions,andy
