I noticed that the mmc only runs at 100mhz 8 bit ddr clock instead of 200mhz
due to a corruption bug so max interface bandwidth is 200 before overheads and such instead of 400
I seen some talk about rockchip chipsets bumping that to 150mhz as the corruption doesnt seem to show its self
to maximize performance and not get the corruption bug
is this something that could be done with the s912 as in the long term i would like to move to mmc
As far as I can tell eMMC clock is determined by Amlogic driver depending on what is supported by eMMC chip. So far it works, I am geting decent R/W rates. I will not touch that code to not break anything.
For example on one of my devices it runs at 200MHz, 8-bit:
