Incompatible version of LPUART Driver

rajtend — Tue, 05 Nov 2024 16:10:47 GMT

Hi,

I am using imxRT1050 EVKB. I want to use LPUART Driver from FreeRTOS.
However, I get a warning as shown below.
If I compile the code and execute it, I get a data bus error.

Can someone tell me how to get compatible version of LPUART driver?

Thanks!

Hi @rajtend ,

Thank you so much for your interest in our products and for using our community.

Please let me know if your project with FreeRTOS.

I use MCUXPresso IDE, the version is same as you.

I import a SDK demo "evkbimxrt1050_freertos_hello", add LPUART3 driver, There are no problem and warning.

Please use a project with FREERTOS ,then add LPUART3.

Wish it helps you.
If you still have question about it, please kindly let me know.

Best Regards

mayliu

Can you change the Mode from Polling to FreeRTOS?
You will see the warning immediately.

Hi @rajtend ,

Hi rajtend, Thank you for your updated information.

Can you tell me how and where you call LPUART_RTOS_xxx functions?

I will verify your modification on my MIMXRT board.

Wish you a nice day~

Best Regards

I was able to resolve this. The receive call expects global buffer and not one allocated on stack. This ways, the UART driver in FreeRTOS is working fine, without crashing.
