5 years ago This was fixed by commit whitequark/libfx2@a06b7f573f71abe6e. Did you run git submodule update?

5 years ago Ahh, this commit wasn't present on the commit pointed to in the revC0 tag.

5 years ago Actually, I don't see how this could be fixed by that commit. The fx2 library appears nowhere in the backtrace. It looks to me like this issue just exists independently in software/glasgow/device/hardware.py.

I just built
firmware.binon 8ae10d25574f583828203a85be58edfd92cbc8c7 and found that it contains over 10 kBytes of text:This seems problematic given that the FX2 has only 8kB of RAM.
As one might expect, attempting to load this firmware onto the device fails:
