Sorry my English is not good.
I'm using LPCLINK2 as LPC4370 evaluation board.
I try to rewrite SPI Flash memory ,after boot from SPIFI.

Debugging below code, LPCSPIFILIB library use model example

(main() located on SRAM.)
int main(void)
{
SystemCoreClockUpdate();
Board_Init();

// spifi initialize
/* Initialize LPCSPIFILIB library, reset the interface */

spifiInit(LPC_SPIFI_BASE, true);

/* Register the family for the device */
spifiRegisterFamily(spifi_REG_FAMILY_CommonCommandSet);

/* Return the number of devices this library supports */
int idx = spifiGetSuppFamilyCount();

/* Get required memory for detected device, this may vary per device family */
uint32_t memSize = spifiGetHandleMemSize(LPC_SPIFI_BASE);
if (memSize == 0) {
/* No device detected, error */
}

uint32_t *lmem = malloc(memSize);

/* Initialize and detect a device and get device context */
SPIFI_HANDLE_T * pSpifi = spifiInitDevice(&lmem, sizeof(lmem), LPC_SPIFI_BASE, SPIFLASH_BASE_ADDRESS);
if (pSpifi == NULL) {
/* Error initializing device */
-->while(1);
}

It has entered the while(1); loop. Why?
In addition.Oddly all memory looks as 0x2000c000

Original Attachment has been moved to: memory_test.zip

Can you debug this project?
Then it would be good to step into the function spifiInitDevice() and find out where it fails. There are several action which can return an error.
The map file of your project looks rather ok, it seems that all relevant objects are in RAM.

I don't know what you mean with "all memory looks as 0x2000c000".
