Non MSD boot on Pi4-CM #75

Closed tetofonta closed 2 years ago

tetofonta commented 3 years ago

I cannot figure out how to boot a kernel from rpiboot. As mentioned in README file, I've copied the boot partition and run rpiboot with -d option without any joy. I had to include the bootcode4.bin from the msd directory, which is what seems the only bootcode available online.

Any suggestion or can anyone point out what I'm doing wrong?

In any case, this is the output of rpiboot:

sudo ./rpiboot -v -v -d boot

You need to add the -l server so that it keeps on running after starting the GPU firmware.
