I bought a generic "EMMC module" meant for Nano Pi.
To be honest it was a trial to see if I can use it as general memory and boot from it with the attached SD module.
The image to it was written from RPi Imager, with first RPi OS 64bit, then 32bit lite.
However, while it was starting, there is no other function than 4 short green LED blinks which means some start*elf file is not found. I remember Rpi is doing some disk magic when it has fresh new media, however, it did not seem so as there was no other LED activity.
The image seems to be written correctly, I see files in windows.
Is it even possible to boot from such modules? Any ideas on how to make it work?
At first, I thought I bricked it, but I was able to boot from the old SD card. I thought it would work like a normal SD card, but guess I am wrong...
