@richard-damon Thank you for the reply.
I have reduced all the memory configuration, I think, the project now compiles and links. However, when I run the project I get a hard fault exception. The task I have is very simple:
void tasktest(void * param)
{
while(1)
{
vTaskDelay(pdMS_TO_TICKS(1000)) ;
//HAL_Delay(500) ;
}
}
I set a breakpoint on the delay line and start the code. I have tried tracing through the delay call and it appears the exception happens when the context switch is done, with the registers looking like a memory/stack corruption has occurred. If, as a simple test, I use the HAL_Delay call the task runs, but of course does not suspend.
This is my FreeRTOS config:

I have increased memory configuration, but this issue remains.
Any pointers to what is occurring would be much appreciated.
