• Checked the issue tracker for similar issues to ensure this is not a duplicate.
• Described the feature in detail and justified the reason for the request.
• Provided specific use cases and examples.

Feature description

Stock micropython binaries (esp32s3) are compiled with
tinyusb support (not hardware cdc-jtag) so user-written
micropython source allows creating custom usb devices.

If we want to integrate micropython and usb-jtag-bridge
one option is to compile micropython with hardware cdc-jtag,
other is to have usb-jtag-bridge written in micropython.

Use cases

Intelligent usb-jtag-bridge that is not only JTAG but also
protocol converter/adapter with serial, wifi, bluetooth, etc.

Often debugging needs additional hardware next to jtag,
with jtag programmable in micropython we can have
many-in-one device.

Hi @emard, thanks for the suggestion, but isn't this more like request for micropython team? But if I understand correctly, you would like to have something like esp-usb-bridge, but implemented in micropython?

[emard]

yes yes, something like esp_usb_bridge.py in micropython would be cool to have. But it's not a hurry, I have still various ideas how could I program onboard fpga with usb esp32s3 which runs micropython. You can also close this issue and/or place it in some future todo

I will close this, but I think you might try to take it to micropython repo and suggest it to them with the link to this repo for inspiration. I do not think it makes much sense for us to maintain two repos with the same purpose, sorry for that.
