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.

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
