General • Using Picotool with a multi-CDC setup

Hi all,

I am using a setup with multiple CDC ports, based on the example here: https://github.com/Noltari/pico-uart-bridge
This works really well and I have expanded this to use 5 virtual serial ports. I now found out that picotool cannot be used anymore to reset the RP2040 into BOOTSEL mode. I have tried to add code to my usb-descriptors.c file as in the files in the pico_stdio_usb directoy in the original SDK, but this breaks the operation of all USB interfaces, and I have no working VCP's anymore.
Does anyone have experience with this can can helop me with a solution?

Code added is:

• TUD_RPI_RESET_DESCRIPTOR(USBD_ITF_RPI_RESET, USBD_STR_RPI_RESET)

with the macro and including the pico/stdio_usb/reset_interface.h file, and adding 1 additional device.
