Zero - USB Boot Button gone
Are you trying to boot from the eMMC?
If so, you can boot from sd card first, then dd the image to eMMC, and then you can boot from eMMC.
The USB button is used to flash eMMC.
i tried like this. but it fails and ended with a boot loop
dd if=/dev/mmcblk0p1 of=/dev/mmcblk2p1 bs=1M status=progress
also tried with if=Dietpi…img
ok, i did it with dietpi-imager
