That will still work, but we need to extend the board identification to "board-name" + "board-revision", as the Green choose the "A335BNLT" board name in the eeprom to remain compatible with older 3.8.x images from last year.. (most of the clones i've talked too want to support the old image too)... So with the 1st byte of the board-revision: All BeagleBone Black's have: 0x30 Seeed's using 0x1A (with the potential to increment the A) Regards,

SeeedStudio BeagleBone Green (BBG) is clone of the BeagleBone Black (BBB) minus the HDMI port and addition of two Grove connectors (i2c2 and usart2).
