General issue report

Hi team,

this example works good with S3, how about P4?

https://github.com/espressif/esp-iot-solution/blob/master/examples/usb/device/usb_uart_bridge

In theory it should be straightforward, assign pins and let it run, but:

• code seems to run correctly
• monitor other devices, all kind of esp32 devkits, works good
• there is problem to flash devkit on our custom PCB with it
• the same setup (wires, PCB etc) just with esp32-S3 instead of P4 works fine, i can flash and monitor

i am using always esp-idf master branch

Thanks

this example should update esp_tinyusb version which support p4.

I am using esp_tinyusb which supports P4.

Like i said, the code seems to work, i can connect and see logs, but i cant flash other esp32 due to timeout in esptool, which cant communicate properly with esp32.
