Re: Invalidate cache

Which IDF version and which chip are you using? We have added an API "esp_cache_msync" in IDF v5.1, but it only works on ESP32-S2 and later chips. ESP32 doesn't have a hardware feature to write back all the cache contents. (It can invalidate the cache, but invalidating cache when the program is runn...

Re: Soft reset to second stage bootloader

You probably can't jump directly into the 2nd stage bootloader because it is not present in RAM when the application runs. (Keeping it present there would waste RAM.) Therefore the boot process has to go through the boot ROM, which would copy the 2nd stage bootloader code into RAM (overwriting part ...

Re: Compile error: API components not found

To troubleshoot this, you can try the following: 1. Identify the source file where the issue occurs. If the error is reported in a header file, then also find the header file. 2. Open build/compile_commands.json and fine the compiler command line which corresponds to the said source file. Does it ha...

Error: esp_usb_jtag: could not find or open device! this indicates that OpenOCD wasn't able to find the device in the system. Could you try to open Device Manager and check which device appears in the system when you plug in the development board? What are its VID and PID? Do they match the expecte...

Re: Does anyone have a good solution for measuring a continues PWM signal?

I haven't tried with PWM, but I did use RMT peripheral on the ESP32 to receive a multi-channel PPM signal from an RC receiver. I guess with PWM it should be even easier. Can you describe the issues you ran to when trying to use RMT to receive PWM?

Seems correct, all releases <=v4.x have used -std=gnu++11. So to summarize,

- IDF v4.4.x and lower — C++11
- IDF v5.0.x — C++20
- IDF v5.1.x — C++23
- (future) IDF v5.2.x — C++23 (expected)

Re: ESP32 S3 Auto detect PSRAM speed

Unfortunately there is no autodetection for this, you'd have to select the interface used by SPIRAM yourself.

Re: esp-matter LoadProhibited error when updating attribute

Are you sure you aren't overflowing the stack of the task where Matter callbacks are dispatched? Perhaps you could try to send a notification to another task from matter callback, and invoke IR related functions from that other task?
