So that's the difference, thanks for the info, much appreciated. To sum
up SWD on the Raspberry Pi probe only good enough for rp2040s and

What do you suggest I use on raspberrypi instead? It is indeed the boot
process I need to debug. It is working OK in Qemu 9.x but does not boot
on real rpi hardware, either rpi3 and rpi4.

I'd maybe try a second RPi running OpenOCD and the GPIO to drive the JTAG
pins on the first RPi:
