Which board is this? Neither "git grep -i P1020RB" nor "find . iname
'*P1020RB*'" yield any result.

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.
