I tried to read more about MeP architecture but there is very little "conventional" info about it
- GCC 3.4 port abandoned http://people.redhat.com/dj/mep/ http://people.redhat.com/dj/mep/ , what compiler is commonly used?
- Wikipedia page https://en.wikipedia.org/wiki/Media-embedded_processor https://en.wikipedia.org/wiki/Media-embedded_processor , well, compare it to RISC-V that contains assembly and microarchitecture details
- guedou 7y agoYes,the idea is to use the Ghidra decompiler to ease reversing new parts of the FlashAir firmware. The MeP-c4 datasheet is available at https://www.datasheetarchive.com/pdf/download.php?id=6693e804e3df834cc0ce6f53df8c5cf03850f3&type=P&term=MeP%2520c-4 https://www.datasheetarchive.com/pdf/download.php?id=6693e80... I had success compiling GCC with MeP support using git and the commit before the removal. Yet, I believe that FlashAir are not compiled with gcc.
