Dear Igor
thanks for your quickly reply
i test the register which you mentioned the result as below.
SRC_SBMR1(0x020d8004) = 0x0000c860
SRC_SBMR2(0x020d801c) = 0x02000001
and we try to catch the signal for CMD and CLK on EMMC ,we think that is right , there is a lot of signal when the board start up ..
below is our DDR info tested by test tool.
and below is the log info for download(i bypass to burn the rootfs due to that spend a lot of time ,and if i download rootfs into emmc ,that is the same).
