Hello,
I am working to connect to a serial link (USB). In order to do that I
have to write this command:
sudo ../../tools/stm32w/serialdump-linux -b115200 -d10000 (keeping in
mind dat*serialdump-linux*, which is in the path, is not a folder,
it's an executable)
To get to the root, I have used: returncode =
subprocess.call(["/usr/bin/sudo", "/usr/bin/id"])
Then to connect to the USB through the command above I tried the
following:
usb =
Popen(['../../tools/stm32w/serialdump-linux','-b115200','-d10000'],
stdout=PIPE, stdin=PIPE, stderr=STDOUT)
usb.communicate()[0]
But I am getting an error, it's considering that serialdump-linux as
a folder!!
Any help how I can run the command?
Many thanks

I resolved the issue, you can do the following:
First method:
args = ("sudo", "../../tools/stm32w/serialdump-linux", "-b115200",
"-d10000")
usb = Popen(args, stdout=PIPE, stdin=PIPE)
usb.wait()
usb.communicate()[0]
Second method:
cmd = 'sudo ../../tools/stm32w/serialdump-linux -b115200 -d10000'
os.system(cmd)
you can run it using cmd and os or using Popen if you need to use stdout
and stdin in your application (which is my case)
PS. -b115200 -d10000 are two options related to USB so you can change
the whole command and use any option you would like to.
Regards
