Thanks. Not been able to find a definitive answer by googling, and unfortunately, although that is an interesting discussion thread, it still seems to be based upon opinion and not indisputable fact.

Thanks, anyway.

As always, my interests lie in barebones assembler from the restart vector onwards, probably trying to relive my first such experiences on a PDP11/20 50 years ago this summer :-)

You might do better with an RK3399 based board as full documentation is openly available for that SOC unlike any of the Broadcom SOCs used in Raspberry Pis.
