Arduino IDE version

1.8.19

Board

Feather ESP32-S3, Feather ESP32-S3 Reverse TFT

ArduinoCore version

Sketch & compiled Log (as attached txt files)

Sketch used: examples/MassStorage/msc_external_flash.ino

Upload settings (Note: I have also tried the TinyUSB partition)

What happened ?

The feather hangs after uploading this example. The USB does not re-enumerate and an MSC USB drive does not appear.

How to reproduce ?

Upload msc_external_flash.ino to an Adafruit ESP32-S3 Feather such as the new Adafruit ESP32-S3 Reverse TFT.

I just did an test with Feather eps32s3 and it seems to work well. There is a few gotcha though

after uploaded, S3 need manual pressing reset button. It is hw issue from espressif
msc_external_flash use FAT file system, you will need to select the partiion scheme with FATFS (not SPIFFS as screenshot)
if flash is not fomartted, you need to format it either using your host PC or with SdFat_format in Adafruit_SPIFlash example as mentioned in the sketch https://github.com/adafruit/Adafruit_TinyUSB_Arduino/blob/master/examples/MassStorage/msc_external_flash/msc_external_flash.ino#L21 . I will make it clearer with the example

Let me know if doing all of above changes work for you.

@hathach This did not work for me. I formatted the flash, used the FAT partition scheme and re-uploaded msc_external_flash. Upon hitting restart, my USB mouse stuttered the serial port never opened nor did the volume mount.

Are you on BSP 2.0.7?

I am using arduino-esp32 at master, it should already included 2.0.7. Can you try

running msc_ramdisk example, it does not use any additional library to check if usb work
if msc_ramdisk does not work on your machine, maybe try to plug it into other machine e.g windows/linux.

Meanwhile I will try to use the exact release version of 2.0.7 to test with.

@hathach Same issue with msc_ramdisk on 2x machines at 2.0.7.

just switch to branch https://github.com/espressif/arduino-esp32/tree/release/v2.x to test, and it indeed has issue with TinyUSB lib, ESP32 repeatedly reset with both S2 and S3. Apparently there is difference between master and branch 2.x. I will try to llook more closely to find the root cause

@brentru v2.0.0 should fix this issue, please give it a try

@hathach Thank you for resolving this issue via v2.0.0! Working for me.
