+# Configuration file for fw_(printenv/setenv) utility.
+# Up to two entries are valid, in this case the redundant
+# environment sector is assumed present.
+# Device offset must be prefixed with 0x to be parsed as a hexadecimal value.
+# On a block device a negative offset is treated as a backwards offset from the
+# end of the device/partition, rather than a forwards offset from the start.

+# Colibri iMX6/Apalis iMX6
+# U-Boot environment is stored at the end of the first eMMC boot partition
+# hence use a negative value. The environment is just in front of the config
+# block which occupies the last sector (hence -0x200)
+# Note that /dev/mmcblk0boot0 by default is read only
+# To use fw_setenv you have to first make it writeable, on the cmdline e.g. by
+# $ echo 0 > /sys/block/mmcblk0boot0/force_ro
+
+# Block device name	Device offset	Env. size
