The U-Boot env file is generated by mkenvimage, which prefixes the variable data with a 4-byte CRC32 by default. ixpreboot.sh previously imported it with `env import -b` as per uboot docs(-b assume binary format (’0’ separated, “00” terminated).), which treats the buffer as raw binary and does not strip the CRC. As a result the first variable's name is parsed a part of CRC. Later variables import correctly because by then the parser is past the CRC. Switching to `env import -c` as per uboot docs (-c assume checksum protected environment format.) makes U-Boot validate and strip the CRC before parsing, so the first variable imports under its real name.
