pi plus 2se

dhester

I have just got am oramge pi plus 2se and the upgrade button has fallen off. The board still boots and is usable but will the loss of the button mean I can't load an os to the emmc?

unixwise

This is how I manage to write the OS to eMMC

hope it helps

Hi, you could use the following command to write OS into EMMC. Hope it could help you.
