I have documentation on some Y-R-CAR-H1-BOARD-EXP board, and I have the R0P7779A00020S board mounted below Marzen. They seem very different as the latter don't have any switches on it. > One of the main changes you have made is adjusting the offset of the > control registers.

Yes, but not all SH4 registers exist on R-Car and the Ether base is 0xFDE00000 according to the datasheet. > Regards > Phil WBR, Sergei
