1. Yes this is normal. The Bootloader only does uploading it doesnt handle the Serial USB (thats handled inside the sketch binary)petronel wrote:Probably I was expecting Download from and Upload to .. it makes more sense to me.
I have 2 other questions now:
1. After a sketch is uploaded and the STM32 is resetting, the Serial connection drop for a second, and I have to close/open the Serial Monitor. Is that normal ?
2. Uploading a sketch that compile ok but crash when running (like my test with RFID) make the DFU / com disappear and getting again "Unknown device". I can still reset the STM32 and upload an working sketch.
2. If you crash the sketch it will crash the USB serial, (see item 1)
