MCU / Orin UART Access#

BMC can access MCU/Orin UART over LAN.

ssh root@<BMC IP> -p 2200

If the UART displays Shell>, the MCU UART is connected. Otherwise, the Orin UART is connected.

To exit the console when you are done, do the following:

  1. Press RETURN, then press shift and tilde 2 times.

    RETURN,  SHIFT + ~ ~
    
  2. Press period (.) to complete.

Set General Purpose Input/Output (GPIO) in BMC to Switch Between MCU and Orin UART#

The default UART console is Orin UART. You can switch between MCU and UART by using the following commands.

Set BMC_GPION1 high to change to IGX Orin UART:

gpioset -m exit gpiochip0 60=1

#or

gpioset -m exit `gpiofind "bmc_gpio_n1"`=1

Set BMC_GPION1 low to change to MCU UART:

gpioset -m exit gpiochip0 60=0

#or

gpioset -m exit `gpiofind "bmc_gpio_n1"`=0
