I want to make boot loader project. So, I try to test Flash Read/Write.
1. Use IC : TMS570LC4357
2. Test Code
uint32_t pre_calculated_crc= 0;
uint32_t firmware_size = 0;
volatile unsigned int oReturnCheck = 0;
volatile uint32_t test_size_data = 0x23143;
volatile uint32_t test_crc_data = 0xA58390;
oReturnCheck = 0;
oReturnCheck = Fapi_BlockErase( 1, 0x00300000, 4);
oReturnCheck = Fapi_BlockErase( 1, 0x00300100, 4);
// Return an error if an access violation occurred.
oReturnCheck = Fapi_BlockProgram( 1, 0x00300000, (unsigned long)&test_size_data, 4);
oReturnCheck = Fapi_BlockProgram( 1, 0x00300100, (unsigned long)&test_crc_data, 4);
if(oReturnCheck)
{
// Indicate that the flash programming failed.
}
Fapi_BlockRead(1, 0x00300000, &firmware_size, 4);
Fapi_BlockRead(1, 0x00300100, &firmware_size, 4);;
3. The Boot Loader map
VECTORS (X) : origin=0x00000000 length=0x00000020
FLASH0 (RX) : origin=0x00000020 length=0x001FFFE0
4. I check the Flash write act very well. But, in the Function(Fapi_BlockRead), Abort is occurred.
I want to know how I can to read flash memory.
