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, -- Robert Nelson https://rcn-ee.com/ -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
