Testing other frequencies I noticed that I made a mistake.
The value set by u-boot in "PLL_DDR Control Register" is 1344MHz:
=> md 0x01C20020 1
01c20020: 90001b10
The "DRAM configuration register" has CLK_SRC_SEL set to PLL_DDR
and the divider M set to 1 (DRAM_DIV_M = 0):
=> md 0x01C202F4 1
01c
Hello,
I found the problem with this board: the DDR frequency. U-boot is
setting it to 648MHz and somehow it is creating instability. I
reduced it to 576MHz and all the problems are gone. I added an opp
table to the dtb and I've tested the board at maximum freq, playing
online videos in chromium (
