Yes, I think they have to have separate builds positioned at well known
locations in flashThe only issue is where would you share any common,
pico2-specific drivers, Some code duplication would be the easiest way.There
are other multicore, asymmetric architectures.What did they do?Sent from my

RP2350 port Thanks for getting it working! I'd like to try out NuttX on the new
Picos,so I'm excited development has started so quickly!Not much advice for the
other questions, but for number 2 maybe there couldjust be a raspberry-pi-pico2
board and the selection between ARM and RISCVis done via Kconfig?Either
preprocessor statements or conditionally including the ARM/RISCVsource files in
Make.deps depending on the configuration settings?MatteoOn Mon, Aug 26, 2024,
