This sets the CPU clocks to 925MHz and DDR to 400MHz, and the correct CONFIG_HPS_MAINPLLGRP_VCO_NUMER should be 79.
Didn't various CV SX run at 800MHz only ? I think only some of them ran at 925MHz, not all of them.
Ah yes, I think I'm lucky to have a 925MHz devkit on my desk. But I think CONFIG_HPS_MAINPLLGRP_VCO_NUMER should be 79, as I cannot get a correct baudrate without it.
Yep, you and me are both lucky. The AV is also 925MHz part.
I have some SoCrates and MCV SoMs which are 800 MHz parts, so I'd like to keep those parts operational, but I think I'll just have to figure something out on a per-board basis.
I'll check the subsequent patch and see if I can pick it up now. Thanks!
