simulator does not work

make unix compiles without errors. make simulate finishes without errors until it tries to start bin/micropython_unix simulate.py.

Is this supposed to work?

I didn't test on arm, but I think it should work. I have a pi4 somewhere so let me check tomorrow and report back.

Thanks a lot! I also tested on rpi2,1gb and rpi3,1gb using raspbian based on bullseye and on cubox. No success. But those two are armv7 and have very little memory. A CuBox-i 4X4 (armv7, 4GB, debian bullseye image provided by NXP) didn't make a difference. I would have tested on a rpi4,8gb if I would have had a hdmi-micro cable at hand.

To really run the simulator on one of those sbc I'd prefer the rock64 or the rpi2, because both of them just have an ethernet an no further wireless communication.

Maybe such a setup could make a good compromise for an (temporary) air-gapped wallet, given that the used storage (and maybe the spi flash) are erased/destroyed properly to prevent data leaks.

I successfully build and ran the simulator on a Pinephone running mobian(bullseye).

Installed armbian focal (based on bullseye) on the rock64 - works.

The problem seems only to show on armv7 or armv8 running old software.
