Re: ESP32-S2 USB-CDC Flashing (Arduino)
OK, I have understood. So, what about "Serial connected to:" option of Arduino IDE? Is it another feature of ESP32 Arduino Core? As far as I understood, the released library of yours and that option are different alternatives, right? Thats right. My library is alternative for espressif library in a...

Re: ESP32-S2 USB-CDC Flashing (Arduino)
CDC flashing will available as long as CDC is running on device, so you have to add it to your code each time.ozgbostan wrote: Thanks for your support and contribution. Now, after uploading the example sketch just one time, the CDC flashing will be always available for the upcoming upload procedures, right?

Re: ESP32-S2 USB-CDC Flashing (Arduino)
I just added persist reboot to my library, which allows to flash without using buttons to enable download mode. My version has small issue, but i think it is better to have it working this way than not having it at all.

In other hand i tested yesterday on windows 10 virtualbox VM and there was issue in OS layer, which was resetting device every few seconds due to slow response (just g...

Re: ESP32-S2 USB-CDC Flashing (Arduino)
By the way, you have just released a library a couple of days ago, does not that library solve the problem that you mentioned about? Yes and no. I am aware that we have issue with tinyusb_init, so i am ignoring return from that function until it wont get fixed in arduino. I also implemented USB per...

Re: ESP32-S2 USB-CDC Flashing (Arduino)
Thanks for the discussion. You have anything in your mind to recommend as a solution? I investigated it a bit today and there is something changed in tinyusb library which is in idf-release/v4.2, since branch esp32s2 works good, and by works good i mean if you have flashed USBSerial example from br...

Re: ESP32 upload failure
This should not be needed, but did you try to enter download mode with buttons?
