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.

Board Support
The board support for an architecture always starts with Qemu support,
this is what each linux_defconfig at the very least sets up. Then
each $BR2_ARCH has additional BSPs, e.g., Banana Pi BPI-R3.
The board/ directory is matched with the configs/*_defconfigs and
the only execption is board/common/, which holds all shared files for
Infix builds.
Each board/$BR2_ARCH/ can then have vendor/product sub-directories
for the BSPs which may contain "fixups" to the base kernel config and
any additional device tree files that should be included as well.
To rebuild a board-specific package, e.g. NanoPi R2S:
