Depois de algum tempo, inicializei meu Cubox i4 Pro. Este microcomputador usa U-Boot, ou pelo menos deveria fazer isso. A caixa não inicializa, no entanto.
Quando conecto meu Mac por micro-USB ou um monitor por HDMI, vejo o seguinte:

E mais alguns. Suspeito que o Error: "autodetectfdt" not definedseja o culpado por não conseguir inicializar. Existe uma maneira de restaurar isso autodetectfdt, de preferência sem piscar todo o cartão SD? Há alguns dados sobre ele que eu gostaria de preservar...
