Function Documentation

FLASH_benchmark_erase_write_read()

uint8_t FLASH_benchmark_erase_write_read	(	uint8_t	chip_num,
		uint32_t	test_data_address,
		uint16_t	test_data_length,
		char *	response_str,
		uint16_t	response_str_len )

Benchmarks the erase/read/write operations on the flash memory module.

Parameters

chip_num	Chip number to use.
test_data_address	Address to erase, write, and then read back from.
test_data_length	Must be <= 512. Otherwise, the verification will fail.
response_str
response_str_len

Returns

0 on success. 1 if erase failed. 2 if write failed. 3 if read failed. 4 if verify failed.

This function will erase the flash memory, write test data to it, read it back, and verify the read data. The test data is a sequence of bytes from 0 to 255. The response_str is valid whether or not there are errors.
