So I'm trying to do some simple store and load from and to my flash memory.
I'm using the nRF51822 with 256 kB flash memory.
My problem looks exactly like this one, but of course no solution was provided.
However, I also do not get to store since I get NRF_ERROR_INVALID_ADDR.
I want to store at 0x3F800.
Below I put down my source code.
Can anyone tell why I get this error and what I'm doing wrong?
#include "mbed.h"
#include <string.h>
extern "C" {
#include "nrf_error.h"
#include "pstorage.h"
#include "crc16.h"
}
pstorage_handle_t pstorage_handle;
uint8_t pstorage_buffer[pstorage_block_size] __attribute__ ((aligned (4)));
Serial pc(USBTX,USBRX);
// Retrieve the handle of a storage page
void PStorage_GetBlockHandle(uint8_t id, pstorage_handle_t *block_handle);
static void PStorage_Callback_Handler(pstorage_handle_t *handle, uint8_t op_code, uint32_t result, uint8_t *p_data, uint32_t data_len)
{
if(op_code == PSTORAGE_STORE_OP_CODE)
{
// Configuration stored reset the system
//wait_ms(100);
//NVIC_SystemReset();
pc.printf("OP Code returned succesfull.\n\r");
}
}
bool PStorage_Init()

return false;
pstorage_module_param_t pstorage_param;
pstorage_param.block_size = 64;
pstorage_param.block_count = 1;
pstorage_param.cb = PStorage_Callback_Handler;
if(pstorage_register(&pstorage_param, &pstorage_handle) != NRF_SUCCESS)
return false;
return true;

And my main file.
pc.baud(115200);
pc.printf("Starting\n");
PStorage_Init();
xacc[1] = 1;
PStorage_Store(0, xacc);
PStorage_Load(0, stored);
pc.printf("Stored = %u \t Load_1 = %u\n", xacc[1], stored[1]);
wait(1);
xacc[1] = 0;
PStorage_Store(0, xacc);
PStorage_Load(0, stored);
pc.printf("Stored = %u \t Load_0 = %u\n", xacc[1], stored[1]);
wait(1);
