SKR 2 not connecting to usb

[dangerousderek]

Hi!
I used the Web builder to compile for the BTT SKR2. I'm not good enough with code to compile grblhal myself, and no combination of settings on the web builder seems to work. The SKR 2 board works fine with marlin, but as soon as I flash the .bin from the web builder it fails to show up as a usb com port. After a bunch of googling, I found a blog that pointed me to this conversation:
https://community.platformio.org/t/difficulty-with-getting-usb-serial-usb-cdc-working/7501/9
They are discussing the usb not working with this chipset, but once again I don't know enough about coding to compile grblhal and fix the usb issue myself. Is there any way to fix this issue with the web builder?
Thanks!

It could be the USB clock beeing off. Which processor is on the board, a 407 or a 429?

Thanks for the quick reply! It's the 407!

It could be due to the basic version (no bootloader) using an incorrect loader file. If this was the one you tried you may try again now. If not I can compile a bootloader version with Eclipse for you to try.

FYI I do not have a board to verify the code with.

Hi everyone.
I have the same problem. I have BTT SKR2 with 407. I don't know how to distinguish between basic and bootloader version. But from webbuilder I tried both in combination with native and virtual usb. Any progress on the topic?
