I use LPC2148 with FreeRTOS and I want to test xSemaphoreGiveFromISR function. I try to use only external interrupt it work but when I use FreeRTOS it doesn’t work. I guess this problem is happen because startup file. I use one startup file with one project it can run freeRTOS but I use another startup file is cannot run freeRTOS but can run external interrupt. I check the different between 2 files I found this
ISR_Stack_Size EQU (UND_Stack_Size + SVC_Stack_Size + ABT_Stack_Size +
FIQ_Stack_Size + IRQ_Stack_Size)
in the project that can run external interrupt but FreeRTOS doesn’t work.
How can I do with startup file?
I use Keil IDE
Thank you
