Upgrade eMMC 4.5 to eMMC 5 any possibility?
« on: February 23, 2015, 04:29:39 pm »
Hi
I have question about that on board memory eMMC v4.5. Do you foresee in the near future to change this eMMC v4.5 which is very slow to a newer type eMMC v5 which bandwidth read/write is several times higher?

emmc seriously bottlenecks the A80 performance in many tests, not just because the emmc 4.5 is slow, but because mmc controller is sort of slow.

The EMMC controller maybe don't support V5.0 spec.
You can refer to the datasheet of A80 here
