I have a GPT-formatted USB hard drive with Arch Linux ARM and am trying to boot to it from my TonidoPlug (v1). I've seen indications that the stock U-Boot on the TonidoPlug (dates from 2009) doesn't support USB drives with GPT-formatted partitions. Is this true?
Next question is, does the Marvell Kirkwood U-boot mentioned here support the TonidoPlug hardware? If so, it seems that I can simply upgrade my U-boot to get GPT support, in order to boot from my USB HD.
Thanks.
