Flash Signature Generation for LPC5410x

Have any of you been able to successfully generate a signature for the flash on LPC5410x using the flash signature generator?

Using the following code snippet...

typedef struct { __I uint32_t RESERVED1[8]; __IO uint32_t FMSSTART; __IO uint32_t FMSSTOP; __I uint32_t RESERVED2[1]; __I uint32_t FMSW0; __I uint32_t FMSW1; __I uint32_t FMSW2; __I uint32_t FMSW3; __I uint32_t RESERVED3[1001]; __I uint32_t FMSTAT; __I uint32_t RESERVED4[1]; __IO uint32_t FMSTATCLR; } LPC_FMC_Type; #define LPC_FMC ((LPC_FMC_Type *) LPC_FMC_BASE) ... uint32_t signature[4]; // 128-bit signature LPC_FMC->FMSTATCLR = (1 << 2); // SIG_DONE_CLR LPC_FMC->FMSSTART = (0x00000000 >> 4) & 0x0001FFFF; LPC_FMC->FMSSTOP = (0x00067FFF >> 4) & 0x0001FFFF; LPC_FMC->FMSSTOP |= (1 << 17); // SIG_START while ( ! (LPC_FMC->FMSTATCLR & (1 << 2) ) ); LPC_FMC->FMSTATCLR = (1 << 2); signature[0] = LPC_FMC->FMSW0; signature[1] = LPC_FMC->FMSW1; signature[2] = LPC_FMC->FMSW2; signature[3] = LPC_FMC->FMSW3; ...

I always end up with a value of 131077 for each of the signature values.
