NUCLEO-F767ZI Mac OS connection issues

Post by sungkhum » Mon Jul 29, 2019 5:39 pm

I'm having trouble transferring files to my NUCLEO-F767ZI on Mac OS. I can connect via REPL fine using:
screen /dev/tty.usbmodem1413 115200

But when I try to use rshell or uPyLoader neither can succeed in getting past just connecting (rshell waits on checking if ubinascii.unhexlify exists ... and if I manually check in REPL the test returns True). And uPyLoader can't transfer the needed "Init transfer files".

I can use uPyLoader on my PC without any issues.

Anyone have success with the NUCLEO-F767ZI on Mac OS?

Similar issue was reported for my IDE (

I solved it by flushing the target file after each written block. This can be useful for rshell as well.
