Unable to debug Marlin (loses SMD during bootload and bootloader is closed source) #162
It appears that the bootloader (closed source) disables the SWD pins.
Is this true? There is no documentation on how to debug MKS Nano V3, not within platformio or anything!
I hope not, because I wish to use this bought to run a delta and the archaic process of transferring the firmware time after time to the SD Card is becoming very tiring for me and the hardware most likely.
