Thanks.

I tried but the python driver still does not find OpenRTK330LI.

Thanks.

Then the green LED will just flash rapidly, no orange or red LED.
I used ST-LINK to program OpenRTK330L_Bootloader_v1.1.1.bin, it is successful, but still green LED flashes rapidly.
Python driver can no longer connect.
I tried python main.py -b 115200 and setting switch to "ST program"

1. uploading the 23.06 prebuilt app on the website,
2. uploading a 23.xx bin or a VSCode OpenRTK330LI project bin via the online bin upload tool,
3. using the python driver command line to upload a 23.xx or custom project bin file,
4. Using PlatformIO within VSCode to upload a custom project bin file)
   do not result in a new firmware being successfully uploaded to the EVK board ("sync failed" error or "upgrade operation failed" error). Some support would in being able to upload firmware to this product would be greatly appreciated.
