Set up debug UART

jreh — Tue, 01 Mar 2022 05:31:36 GMT

Brand new to NXP and their tools, sorry. Using the Xpresso GUI can set up gpios and FlexComm7 as an UART, hopefully for the PRINTF function. This is for a custom product board and the h/w designer chose the pins. The pin configuration is good. When I open Utilities/DebugConsole and set the UART Conf/Peripheral to Flexcomm7 they both, (Flexcomm7 and DebugConsole), go red, with errors.

For the Flexcomm Interface USART-CMSIS the peripheral box, Flexcomm7, is red.

For the Debug Console the peripheral box, Flexcomm7, is red along with Clock source freq.

Any help would be appreciated.

I see you create private case, I will reply you on that place.

Hi,

The DebugConsole component does not use the FlexComm component, it initializes (and allocates) the FlexCom peripheral on it's own. That's probably why you see the problem there. The problems details are shown in the tooltips and in the problems view.

I suggest to use the following steps:

- Remove the FlexComm component that uses the FlexCom7 (using context menu 'Remove' in the Components view) and keep only the DebugConsole

- In the DebugConsole, in the Serial port configuration, ensure you have selected the FlexComm7

- If there is disabled clock, use the context menu (right click the green bulb icon) and select 'Enable FXCOM7 clock' to simply enable the clock:

Please let us know if you'd need more help.
