Hi Alice,
I am using the standard LPCXpresso 45608 board from NXP but I discovered that my "some issues" are related to the program I'm debugging.
Without FreeRTOS I don't see a problem but with FreeRTOS it suddenly becomes unstable.
It seems like I can view/watch standard variables but no structures.
I took the lpcxpresso54608_freertos_generic example program from the SDK (SDK_2.x_LPCXpresso54608 version 2.5.0).
This example works but when I add some lines of code I can reproducethe same error as in my own application.
To the prvQueueSendTask I added just two lines of code. See the changed function:
static void prvQueueSendTask(void *pvParameters)
{
TickType_t xNextWakeTime;
const uint32_t ulValueToSend = 100UL;
TaskStatus_t task_list;
/* Initialise xNextWakeTime - this only needs to be done once. */
xNextWakeTime = xTaskGetTickCount();
for (;;)
{
/* Place this task in the blocked state until it is time to run again.
The block time is specified in ticks, the constant used converts ticks
to ms. While in the Blocked state this task will not consume any CPU
time. */
vTaskDelayUntil(&xNextWakeTime, mainQUEUE_SEND_PERIOD_MS);
task_list.pcTaskName = "bla";
/* Send to the queue - causing the queue receive task to unblock and
increment its counter. 0 is used as the block time so the sending
operation will not block - it shouldn't need to block as the queue
should always be empty at this point in the code. */
xQueueSend(xQueue, &ulValueToSend, 0);
}
}TaskStatus_t task_list; and task_list.pcTaskName="bla"; , on lines 5 and 17, are added.
This just adds a structure to trigger my debugging problem.
When I place a breakpoint in the code to stop in this function (FreeRTOS task), I can view the variables used and continu the program. But as soon as I hover over "task_list", the debugger is corrupted. When I press Resume (F8), the program does not continue and I get an error message from MCUXpresso:
This problem only seems to pop up when I debug FreeRTOS tasks and try to view structures or arrays of structures.
Regards,
Rob
Hello Rob,
Please choose "All-Stop" at the IDE Debug Mode:
And about debug FreeRTOS project on MCUXpresso IDE, please refer to "MCUXpresso_IDE_FreeRTOS_Debug_Guide.pdf", I attached it for you.
Hope it helps,
Have a great day,
TIC
