Hi,
My imx6q board sometimes can't launched from internal emmc.
At this time i found the launch interface was switched to OTG.
I modified the u-boot under MFG firmware folder and made the launch procedure paused
while the mfg otg runing.
In the u-boot enviroment i got the 0x020d8004 register content was 0x00000000 by md command at this time.
But in the correct emmc launching procedure, this register content should be 0x00003860.
I am confused why this register sometimes changed to 0x00000000 in my board.
Below is the md command results while my board can't launched by emmc:
=> md 0x020d8004
020d8004: 00000000 00000001 00000000 00000000 ................
020d8014: 00000000 0000001f 20000001 00000000 ........... ....
020d8024: 00000000 00000000 00000000 00000000 ................
And below is the md command results while the board work correclty.
=> md 0x020d8004
020d8004: 00003860 00000000 00000000 00000000 `8..............
020d8014: 00000000 0000001f 22000001 00000000 ..........."....
Please give me some advise for this question, thanks in advance.
