Hi Anatolij,
Thank you very much for solving the problem. After commenting out the line within /etc/fw_env.config the fw_printenv tool now works as expected.
Regards, Robert

The content of /etc/fw_env.config is as follows: cat /etc/fw_env.config # Configuration file for fw_(printenv/setenv) utility. # Up to two entries are valid, in this case the redundant # environment sector is assumed present.
The above statement is a hint.
# Notice, that the "Number of sectors" is ignored on NOR and SPI-dataflash. # Futhermore, if the Flash sector size is ommitted, this value is assumed to # be the same as the Environment size, which is valid for NOR and SPI-dataflash
# THIS IS VALID FOR TQMa6x eMMC-card only! # eMMC Block device access /dev/mmcblk00x1000000x2000 # if using with redundant env /dev/mmcblk00x1020000x2000
Comment out the above line and try again.

hexdump -C -s 0x100000 -n 8192 /dev/mmcblk0 00100000 95 fc 63 38 61 64 64 63 6d 61 3d 73 65 74 65 6e |..c8addcma=seten| 00100010 76 20 62 6f 6f 74 61 72 67 73 20 24 7b 62 6f 6f |v bootargs ${boo|
It looks like this U-Boot configuration does not use redundant environment, so you must have only one entry in /etc/fw_env.config.
