ESP32-P4 RV32IMA Emulator (Running Linux)

https://github.com/Epiczhul/esp32p4-rv32ima

Hey,
Ive been working on porting the uc-rv32ima emulator
from the ESP32-C3 to the ESP32-P4.

So far, the emulator itself is running great!
Ive successfully booted a prebuilt nommu RV32IMA Linux image on it!

The only issue Im currently facing is getting input over UART/JTAG to work. Everything else seems solid.

If anyone has experience with ESP32-P4 peripherals or JTAG/UART input handling in this context, I'd really appreciate any insights or suggestions!
