Use case #1

In this use case, the CRC module is configured for:

• Performing CRC on an address range in flash
• Using CRC-32

This use case shows how to calculate the checksum for an address range in flash.

Setup steps

Example code

An address in flash must be defined:

#define FLASHADDR      0x0300

Add to application initialization:

sysclk_init();

Workflow

1. Initialize system clock:

   • sysclk_init(); 

Usage steps

Example code

uint32_t checksum;
checksum = crc_flash_checksum(CRC_FLASH_RANGE, FLASHADDR, 4);

Workflow

1. Calculate the checksum of 4 bytes in flash from FLASHADDR

   • checksum = crc_flash_checksum(CRC_FLASH_RANGE, FLASHADDR, 4);
