The Renesas board I am using behaves as a USB to UART adapter through /dev/ttyACM0 at 115200bps. Created the board instance in device dictionary file as:
{% extends 'rza1h.jinja2' %}
{% set board_id = '0000000000001' %}
{% set console_device = 'ttyACM0' %}
{% set baud_rate = baud_rate|default(115200) %}
{% set usb_mass_device = '/dev/serial/by-id/usb-Renesas_Electronics_Corporation_Renesas_RSK_USB_Serial_Port_0000000000001-if00' %}
{% set connection_list = ['usb0'] %}
{% set connection_tags = {'usb0': ['primary', 'telnet']} %}
{% set connection_commands = {'usb0': 'telnet localhost 2000'} %}
With the above configuration, Dispatcher(Remote worker) flashes the board through JLink.And I can see flashing log in the Job console.

But Even i specified the UART connection like (/dev/ttyACM0, 115200bps). I am not getting the u-boot logs on /dev/ttyACM0. Did i miss any other configuration to add in device dictionary???.
Manaually, I can able to see uboot prints on the console through minicom with /dev/ttyACM0 with 115200bps.

Attaching logs for reference.

Thanks
