Compiling and bugs

[mpiani]

I'm sorry to ask a very newbie question, but given the relevance of the project would someone care to give some hints on how to compile the project? I was able to extract the firmware. Although the firmware version was the same, the checksum was different, fixed that, the compiler asks for breath.Bin and asks if I performed make, which I did without result. Another problem is stubs which says there is no target. How should I proceed, please?

Technically (as far as I understand it) you do not need to make, unless you want breath and graph. For patch-airsense, just comment out patch_code or reference #33

Thank you for the reply. I was able to generate unlocked-stm32.bin by adjusting the hash on the patch, but my understanding is that without breath.bin the cvap and other functions would not become available. Can anyone confirm that? If so, how to compile breath.c or breath.o and the others?

I'm not sure, but I think the compilation requires a xml generated by Ghidra (could try importing it using cortex as the language). Haven't really looked into it too deeply this far. Nonetheless, if you do compile it and generate the firmware, be aware the hex comparisons revealed that the breath.bin offset location for 306 is different than the 401 one, but it may still run (like said, haven't taken the time yet to test this yet).

Perhaps someone with better knowledge can help you with this
