initializing SDRAM Fail on Pine A64+ with 2GB RAM
#1
I've flashed Android 5.1.1 image (March dd image) to a micro SD card, and after spending some time to find a power supply + USB cable combination that would actually boot the board, I get the red LED always on with the following log looping in the serial console:


Code:

set pll end

rtc[4] value = 0x00000000
rtc[5] value = 0x00000000

initializing SDRAM Fail.
It looks like some hardware issue with the RAM on the board. Is there a way to set lower DRAM frequency to see if that fixes it?
