[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"

- 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

Next seems to be /etc/fw_env.config

Do you really know the env size is the same as the sector size?
Sometimes one define a smaller space for faster reading.
Have you tried to dd the mtd2 into an file and investigate it (the env
structure is quite simple and should easily be understood when reading
the code).

(re-formatted for better readability)

That's the 'default env' defined in fw_env.h, not the default env of
your board!

That's not true! You can use an older fw_printenv tool to read the
environment of a newer u-boot. The environment format is fix since ages
and will not change cause we want to read an older environment with an
newer u-boot .. so that's obvious.

This means your u-boot is not configured. Somewhere in 2012 a commit
stopped building env target for unconfigured u-boot. There where a lot
of discussion around, unfortunately no solution was found. Maybe your
complaint gives some new input to that.
So a 'make <your board name>_config' before 'make
HOSTCC=${CROSS_COMPILE}gcc env' should solve your issue.
