Just to verify, did you test with the entire series applied? (especially the PLL1 clk application changes) You may try dropping the highest operating point, it's probably overly optimistic for Orange Pi One. Is the power supply/cable you're using hard enough? Where during the boot process does it lock up? regards, Ondrej > Thanks > > Michal > -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
