Arduino ESP32 core 3.3.8 shows ~55kB less available internal RAM comparing to 3.3.7

For my project (audio) it is critical to fit as much data as ...

Hello,
I have a WT9932P4-TINY devboard which carries just ESP32P4, no C6. I try to port some of my projects to P4, and here are some troubles that I have.
The board has 2 USB-C connectors, one FUSB (full-speed) used for powering, uploading and debugging (connected thru IO24, IO25), and the other ...

ESP_Sprite ESP_Me-no-dev thank you!

In 2.x.x it was a mandatory to specify the port number in most setting and operating functions, but in the new 3.x.x API I don't find where to specify if it is I2S0 or I2S1. Is it no longer possible at all, or do I have to use lower level access to specify the port number?

This must have been my corrupted setup. Reinstalled plugin, rebooted, and it worked.

What partition scheme are you using?
I tried almost every one that would fit the files. Which one should I choose? It feels like there's not a lot 16MB schemes, is it?
About the errors, as I can remember, on start the example app was telling about wrong directory pair or tuple or whatever {0,1 ...

Thanks for your reply, I've already tried that example, and it works fine as well as my app, when it comes to operating with LittleFS from within an app. But when I upload files thru the IDE, they just won't be there and the apps don't see the FS. So I wonder if it's just my corrupted setup, or the ...

Within an Arduino project I have a 'data' folder, and if I use ESP32 board, 'data' contents is freely uploading to the flash memory via 'Tools'->'ESP sketch data upload'. But when I use ESP32S3 board, this same tool doesn't do the job. It shows that it's ok, and progress goes from 0% to 100% and ...

Hello, I also get confused when dealing with COM ports of S3. I use these ports with MIDI library, and I haven't yet made it clear nor found a universal solution for different versions of ESP Arduino core. But here's what I've found for now:
Core 2.0.17
When a board doesn't have a dedicated UART ...

The ESP32's RAM is somewhat 'segmented' in hardware (see e.g. here ); there's Instruction RAM (IRAM) and Data RAM (DRAM), where 192kb of IRAM are not available as general data storage, and there's a limit of 160kb for static allocations according to https://docs.espressif.com/projects/esp-idf/en ...
