Yeah, I've tried to keep the original bootloader that came on the first SD card image that was used on that device. But am starting to think that it's time to stop my bootloader independence jihad, since appended DTB booting is so broken - have seen similar problems on SoCs from other vendors as well :-( > And yeah, I feel your pain about power cycling BeagleBone-White.

Here I use a USB cable with VBUS sliced and then connected to an Ethernet-controlled DC relay. But there's a power delivery issue where, under some conditions, supplemental power has to be supplied through the DC jack also, requiring two separate contacts to be switched :-( - Paul -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
