not able to configure crypto chip

Message below:

We weren't able to configure the Crypto Chip. Couldn't configure board at port /dev/ttyACM0. Upload failed with error: Reset before upload: 1200bps Touch: Open port /dev/ttyACM0: Permission denied

what to do now?

Hi @dirknau, this error could show up when your OS user doesn't have the right permissions to open that port. If you are on Linux, maybe you are not in the dialout group. You can verify this running this command on a terminal:


For example, the output of my console when I run that command is: albertian adm dialout cdrom sudo docker and those are all the groups I am part of. If you do not see dialout in your groups, you can add it with this command:

sudo adduser $USER dialout

After doing this, it's possible that you'll have to log out and log in again with your user to make it work. Once you've logged in and again, you should not see that error anymore.
