Compile kernel /Android and can't detect SDHC from Kernel
(01-03-2018, 12:55 AM)spbrain Wrote: Hello?

I found how to compile compile pine64 android 5.1.1 from

I modified some parameters (LPDDR3 define from uboot) and I made sun50iw1p1_android_Baomi-db1000_uart0.img and write to sdcard using Phoenix program(Start Up Option).

Then finally confirmed the boot screen.

But Strangely, system.img was not mounted.

console output is

  30.041548] fs_mgr: __mount(source=/dev/block/by-name/system,target=/system,type=ext4)=-1
[   30.050642] fs_mgr: Failed to mount an un-encryptable or wiped partition on/dev/block/by-name/system at /system options: (null) error: No such file or directory

And I found problem log from kernel message.
As Image from offical site "", 
Linux Kernel found "mmcblk0".
Log is 
9.929729] mmc0: new high speed SDHC card at address 59b4
9.930831] mmcblk0: mmc0:59b4 USD00 29.5 GiB
But compiled linux kernel can not found SDHC card.

I tried 8GB SDHC Card but it same.
What do I modify bootloader config or kernel ??
How do I fix this problem?

SD Card Init Log is below from kernel and no detect SDHC card
