Which board is this?

Considering that you're trying this on a custom board, and assuming "P1020RB" is a nickname for a board supported in mainline U-Boot, there are two possibilities: 1) the custom board uses exactly the same U-Boot (source, configuration and binaries) as P1020RB, and the issue is in HW, in which case we can barely help; 2) the custom board uses a custom U-Boot, and we can barely help too, as this issue is not about (recent) mainline U-Boot code. > manukumar > signal-networks Amicalement, -- Albert. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
