An even better, answer, look on side of the board, there is a bar code with the coded: BWA5***** that's what the device tester was supposed to write to the eeprom. ;) > This (non-functioning) BBBW was purchased in Dec 2018 (just now putting it > into service).

Well, you did have this old version of u-boot installed to the eMMC: bootloader:[eMMC-(default)]:[/dev/mmcblk1]:[U-Boot 2016.11-rc3-00002-g73df7f]:[location: dd MBR] So the overide probably just didn't work..
