Cannot enter upgrade mode when write SD image to eMMC

VIM3

Hello, I have tried these methods (except serial mode) according to https://docs.khadas.com/vim3/HowToWriteSDImageToEmmc.html.

When I press the function keyboard, I have seen blue light. But it turn to white light soon.

The MRegister Mode also has no response.

@cencen if the white light comes you should have successfully booted linux from the SD card, did it not boot ?

Best of all, I think, if the stock Android will initially be on eMMC, and then you try to do it again.

@cencen if it won’t boot into Linux on the SD card if you have the 4.9 kernel image and uboot on the eMMC, this is a known thing.

I used U driver not SD card. it would have an impact?

It is better to follow strictly the instructions you refer to! Good luck to you!
