B-L072Z-LRWAN1 Arduino Sketch Uploading Error

ChaseYoDream commented 3 years ago

I'm having issues getting the Arduino sketch to upload. I followed the instructions and my device shows up as COM( B-L072Z-LRWAN1). Here is the error report I'm seeing:

the selected serial port

Any help would be appreciated.

Is your board using the CMWX1ZZABZ-078 module? Did you put the board into boot mode before trying to flash?

It uses the CMWX1ZZABZ-091 module. I am not sure how to put this dev board into boot mode. I read something about toggling reset while pressing down boot. The only other button is User.

Yes, you can hold boot to GND while powering on or hold boot to GND and press reset. But it needs to be in boot mode to accept new programming as far as I know.

Maybe switch to this https://www.tindie.com/products/tleracorp/grasshopper-loralorawan-development-board/ ?

No luck with holding Boot0 to GND, and powering up or pressing RESET. I have two of these DEV boards free from work so naturally I'm going to try them out.

kriswiner commented 3 years ago

No idea, maybe ask at the ST forum then?

What board is it? What board variant are you using? Via SWD or USB?
