I am currently trying to use micropython on an arduino Nano 33 BLE using MacOS. Following the instructions from arduino website I was able to complete steps 1-3. At step 4, I can find the bossac file but when I try to run the provided command:
bossac -e -w —offset=0x16000 —port=usbmodem14201 -i -d -U -R file.bin
the terminal says no device
found on usbmodem14201 which is a port appearing under the nano board in the IDE.
As a sanity check I ran serialportlist in matlab and the same port was returned when the Nano is plugged in.
I even ran ioreg -p IOUSB in terminal and found the nano: ‘’’ Arduino Nano 33 BLE@14200000 <class AppleUSBDevice, id 0x100008674, re$ ‘’’
That 142… number didn’t work either.
What am I doing wrong?
