Support needed for NXP KL25Z Freedom board
-
Hello,
I've been practicing ARM programming over NXP's Kinetis series KL25Z board. Unlike the kinetis HAL approach, I am practicing entirely using baremetal coding with Keil U vision. I am facing problems in coding the UART programme of this board. If anyone has any prior experience over this board please do help me out guys. I have attached the link for the datasheet of this board FRDM KL25Z Datasheet LinkThanks in advance

Hi @kowshik1729 ,
Could you please specify what problem you are facing while using UART in KL25Z? it will be more helpful to understand your situation. also, try to attach some useful error log.

BaseType_t xQueueSendFromISR ( QueueHandle_t xQueue, const void *pvItemToQueue, BaseType_t *pxHigherPriorityTaskWoken );I was trying to pass a pointer. That was the issue.

Here is my code. I did some modification in this.
Check 70th line of this location.
