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:
Press RETURN, then press shift and tilde 2 times.
RETURN, SHIFT + ~ ~
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
