Getting started: Uploading design: Permission denied (Linux)

[philtomson]

I followed the following steps for uploading the design from the Getting Started doc:

Uploading your design (Mac/Linux) For Linux:

In first monitor terminal:

sudo bash stty -F /dev/ttyACM0 raw cat /dev/ttyACM0

Then in another programming terminal:

sudo cat chip.bin >/dev/ttyACM0

However, when I do that last step I see:

$ sudo cat chip.bin >/dev/ttyACM0 bash: /dev/ttyACM0: Permission denied

Checking the permissions:

$ sudo ls -lart /dev/ttyACM0
crw-rw---- 1 root dialout 166, 0 Mar 1 21:07 /dev/ttyACM0

I'm running on Ubuntu Linux 17.10 if that makes any difference.

Sorry for the delay Phil the documentation has been updated, the relevant part is:

sudo bash
usermod -a -G tty yourUserName
usermod -a -G dialout yourUserName
stty -F /dev/ttyACM0 raw
cat /dev/ttyACM0
