Tool/software:
Hi,
I am following SDL demo application but my project also uses FreeRTOS. I don't understand how to use SL_CRC_Calculate() function, how to calculate ulFlashEndAddr?
Is there some connection between .cinit and ulFlashEndAddr?
crcAtInit_FLASH = SL_CRC_Calculate((uint64 *)((uint32)&ulFlashStartAddr), ((((uint32)&ulFlashEndAddr)-((uint32)&ulFlashStartAddr)) >> 3));
Here is my linker script. Is there need to change something in linker script?
