I built a JIT compilation system for ESP32-P4 that eliminates firmware reflashing during development.

PROBLEM IT SOLVES:
Traditional ESP32 workflow: Write code → Compile → Flash → Test = 30-60 seconds
P4-JIT workflow: Write code → Upload → Test = 2-3 seconds

KEY FEATURES:
- Native RISC-V execution ...

ESP32-P4 Cache Preload API Test Results

Summary

Thank you MicroController for the suggestion to use the asynchronous pattern. I implemented your recommended approach and compared it against optimized CPU copy as a baseline. Unfortunately, the results confirm that Cache_Start_L2_Cache_Preload ...

What is the proper way to use Cache_Start_L2_Cache_Preload()
from esp-idf-v5.5\components\esp_rom\esp32p4\include\esp32p4\rom\cache.h
on ESP32-P4 from application code? The function returns
instantly (2-7 μs for 128 KB) and shows unrealistic bandwidth.
Can you provide:
1. Correct usage example
2 ...
