1.51 CLASSB_FlashCRCTest
Function
CLASSB_TEST_STATUS CLASSB_FlashCRCTest(uint32_t start_addr, uint32_t test_size, uint32_t crc_val, bool running_context);
Summary
This self-test checks the internal Flash program memory to detect single bit faults.
Description
This self-test generates CRC-32 checksum for the given memory area and compares it with the expected checksum.
Precondition
None.
Parameters
start_addr - Starting address of the memory block.
test_size - Size of the memory block.
crc_val - Expected CRC-32 checksum.
running_context - False for startup test. True for run-time test.
Returns
CLASSB_TEST_STATUS - Status of the test.
Example
CLASSB_TEST_STATUS classb_test_status = CLASSB_TEST_NOT_EXECUTED; // Perform run-time test of the internal Flash classb_test_status = CLASSB_FlashCRCTest(0, 0xFE000, *(uint32_t *)FLASH_CRC32_ADDR, true);
Remarks
This self-test can be used during startup as well as run-time. If a failure is detected, this self-test remains in an infinite loop to avoid unsafe code execution.
