Boot from usb with an usb microsdreader and emmc (microsd)


I have a strange setup, an emmc with microsd interface that I use with raspberry. Being bulky I wanted to connect it via microusb / usb3 adapter in the internal connection. Unfortunately the system does not seem to allow booting, I tested the adapter on a PC and it works fine. From the boot of the raspberry it seems the GTP table is not recognized. Obviously I set up boot from usb but it didn’t help.

Try this article it helped me.
Particularly the last third of the article on booting.
