Serial via USB
toogooda opened this issue · comments
Got it to upload but then com port disappears is there supposed to be serial support when using this boot-loader?
After flashing boot loader with stlink
It does not show as a com port but does not error.
Output of upload

does not exist or your board is not connected
No issues using serial/stlink or maple bootloader
It uses the HID interface, not serial.

Yes thanks, my question is does that then mean I can't get my serial debug output via the usb because it is being used as a HID or is this part of the bug that then stops all other uploads after the first one?
If you use this bootloader, then you need to use the HID uploader. Once your sketch is running, it will enable the serial port.
(This is my recollection, I haven't actually used this device for a while.)

Great thank you that is what I wanted to know. I am using the ST uploader HID option so there seems to be a bug with it. As it does the upload but then the COM port fails and there is no serial output.
Is this still active? great idea but looks like its not actively being worked on.
what core did you use?
it work so what you want to add/change?

Upload works first time only but then no serial is possible which is a show stopper. Further uploads all fail until i flash the bootloader again.
Tried it in multiple devices.
Used latest version and Win10 and arduino IDE
ok but what core you use for it?
