Hi,
I am playing with raw repl, and this is a so good tool.
But if I run two time this file :

import sys
from rshell import main
from rshell import pyboard

pyb = pyboard.Pyboard('COM4')

pyb.enter_raw_repl()
sys.stdout.write(pyb.exec("print(1+1)"))
pyb.exit_raw_repl()

I get a error : raise PyboardError('failed to access ' + device)

PyboardError: failed to access COM4

if I run twice the script.
I need to reset the Pyboard to have the script running right again.

Any information about this ?

I wonder if you need to explicitly close the connection at the end of the script?

Code: Select all

pyb.close()

(I would have assumed Windows would do this for you on termination, but worth trying)
