Hi,
....
Testing with A10 Gemei G9 Tablet, FEL mode is broken:
a) With usb-boot via fel:
I get following error/warning: Loading Environment from FAT... Card did not respond to voltage select!
=> mmc list mmc@1c0f000: 0 ### All commands below stalls for a bit (~2 seconds), but return nothing => mmc info => mmc dev 0 => mmc part
Similar issue with A20 Olinuxino Lime2 revk with SPI.
a) Fel mode usb-boot failure (cannot properly initialize sd / emmc) b) SPI boot failure (cannot properly initialize sd / emmc)
c) Regular SD-card boot works ok! d) eMMC boot works ok!
Can you please try whether the patch below fixes this? At least it worked for me with FEL booting my Pine64-LTS.
Not totally happy with it, but it seems like we do a similar trick for I2C anyway, so ...
Yes, it fixes it.
Tested on A20-Olinuxino-Lime2-emmc.
PS. Comment regarding i2c looks a bit odd..
Cheers, Andre
