UART device identification in SPSDK

Devices connected to host PC using UART could be identified by name identifying serial port COMx and speed defining baud rate, e.g. 9600, 57600, 115200.

UART detection using nxpdevscan

UART under Linux

Several steps need to be performed before nxpdevscan and SPSDK can list and use NXP devices connected to the host PC under Linux.

By default on Ubuntu tty serial devices are only accessible to users in group dialout. The permissions for /dev/ttyACM0 can be permanently solved by adding the user to the dialout group:

sudo usermod -a -G dialout $USER

Then the user has to perform logout and login from the system for the group changes to take effect. Afterward, the UART device is shown in nxpdevscan and ready for use.
