Android 9 from eMMC with ayufan SPI uboot - octavian - 08-17-2019
Hi guys and gals,
I was wondering if anyone managed to boot the already compiled Android 9 image from eMMC. I am using ayufan's SPI flash U-boot and I get strange errors like:
{code}
switch to partitions #0, OK
mmc0(part 0) is current device
Failed to mount ext2 filesystem...
** Unrecognized filesystem type **
Card did not respond to voltage select!
mmc_init: -95, time 9
{code}
or timeout when trying to read from the mmc.
The SD version works fine, I have not issues.
Furthermore, not even the older Android versions work from eMMC and the SPI U-boot (same errors) but in this case, if I disable the SPI flash, they will boot correctly as opposed to Android 9 which won't boot from regardless.
I'm going to try a linux image on the mmc next, see if I get any different results.
Has anyone encountered this before? please let me know about your experience.
Thanks,
Octavian
PS. I have tried 2 versions of the SPI flash image, the latest and this one https://github.com/ayufan-rock64/linux-u-boot/releases/tag/2017.09-rockchip-ayufan-1037-gf9f19116f1
Edit: Yes, Linux works perfectly

I was only able to get one of the emmc android 7.1.x images to boot, but the browser kept crashing during use.
