UART2 Tx and Rx Pins are not pulling down to "0"

Hi Team

I have designed im8mp custom board. While debugging through UART2 the Tx and Rx pins are not pulling down during the debug as in EVK because of this I am getting the prints on the terminal but unable to stop at UBOOT. The processor is able to receive the signal but unable to respond.

 

With Regards,

Suresh Gondi

Hello @Suresh123 

 

It appears a device tree issue. Please refer to:

imx8mp-evk.dts - chosen

imx8mp-evk.dts - uart2 node

imx8mp-evk.dts - pinctrl

 

You can refer to IMX8MPLUS  software because you are using the same UART for CORTEX-A debug.

 

Best reagrds.

 

Salas.
