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} som...

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 the...

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 chi...

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/st...

Ok... for those interested. I still wonder how I can change the size of memory segments in Arduino (if possible at all). The solution for me right now is declaring members of a class as pointer types instead of typed variables, and then initializing them in runtime with new or malloc() etc. Some are...

I have a project that is compiled and run with no problems when target is ESP32S3, but won't compile when I set ESP32. It sais c:/users/x/appdata/local/arduino15/packages/esp32/tools/xtensa-esp32-elf-gcc/esp-2021r2-patch5-8.4.0/bin/../lib/gcc/xtensa-esp32-elf/8.4.0/../../../../xtensa-esp32-elf/bin/l...

I allocate buffers using malloc(), but only once per global init, so I doubt this to be an issue. After that I use pointer arithmetic to access these arrays. The matter is when I use heap_caps_malloc( BUF_SIZE_BYTES , MALLOC_CAP_INTERNAL) then it works fast enough, but this obviously limits the size...

I use ESP32-S3 for audio processing, and wonder if I can improve performance. As I can figure out, the bottleneck now is caching mechanism for PSRAM. Am I able of doing something around it within Arduino? Can I turn caching off, and do all the memory stuff in-app, cause actually I operate block-wise...
