@ESP_iggr that was a little bit stupid of me :shock: :lol: , i changed it and voila it worked! Thank you! With my SD or eMMC at 40mhz, 4-width com I can achieve 0.8 MB/s... Put MSC fifo size at 8192 (bigger not possible -> then it will automatically step down to 512). Do you think it could be faster?

Yes, it should be very similar to that example, except that you would call sdmmc_write_sectors instead of wear_levilling functions. Hi ESP_iggr, I'm stuck with the SD connection with TinyUSB. After usb_init() I mount and connect the SD card (first tested with the SD card sample if I can access) and...

@ESP_igrr That would be awesome! Do you think it's possible to use an attached sd-mmc card or chip to redirect to USB? I'm looking for a nice solution to put data on a card or chip and read out by USB. Was also looking at a hardware solution like the MAX14500/14502, but it seems this chip is outdate...

It is possible if you know how to use assembly. Otherwise use the ESP32-S3, it can use a C orientated ULP to measure ADC and I2C.

Did you enable bluetooth in menuconfig?

I don't understand why the example is reading/writing to an USB stick and not acting like an USB stick / device? Would be awesome to just drag/drop to the ESP and preferably also to connected flash/emmc.

Hi jmadsenee, We don't have an example of USB device MSC class yet, sorry about that. I happen to have something similar in this personal project: https://github.com/igrr/esp32s2-wasm-demo/tree/main/firmware/main If you ignore the WebAssembly parts of that application, essentially it allows using a...

Hi, I bought a ESP32-S3 development board to test the USB connection for flashing/debugging and I can flash to the board, but am stuck debugging it. The documentation only mentions steps for eclips and the command line to work. I am working on a Mac, updated to the latest master IDF. (ESP-IDF v5.1-d...

Every week I do a:

git pull

git submodule update --init --recursive

If I change the bt.c, it will give a message that it won't change the file (previously never needed to do), now i just remove that file, update and then add the esp-timer.h
