"cannot use" Define "cannot use"? If you mean the PSRAM that sits on the same bus in e.g. the Wrover modules; it's accessed via the same mechanism XIP uses so outside of the times you need to do something bypassing that mechanism (specifically flash erases and writes, in which case most code is sus...

Well, if you build your program using esp-idf, it always uses XIP for most of the code because otherwise most programs wouldn't fit in memory. But if you want specifics, run 'idf.py size', the part where it says 'flash code' will be executed as XIP. (Something similar goes for 'flash data' but it's...

ESP-IDF already uses XIP for the large majority of the code generated. Is there anything specific that you want to achieve with this?

Thank you for replying. How to detect that XIP is enabled?

Hello. I have seen that esp32 support XIP ( https://open4tech.com/execute-place-xip-memory-model/ ). And I also found that some changes to the linker script can enable it ( https://github.com/zephyrproject-rtos/zephyr/pull/30424 as it was done here). I am interested how to do this with esp-idf. Mayb...

I have ported custom graphic library for lcd displays on esp32, I am using hw spi as in the example provided with esp-idf. The speed(not freq) of filling screen is super low. I tried 26MHz and 10MHz config, the esp32 seems to be the slowest mcu I tried for my lib. Can't figure out what is happening!
