Hi,
We use nrf52840 and SDK 17.0.2 with Softdevice S340
We have a very strange problem and need help from Nordic. Below is my source code.
uint32_t bootloader_start_addr = 0xF2000;
static void power_manage(void)
{
#ifdef SOFTDEVICE_PRESENT
(void) sd_app_evt_wait();
#else
__WFE();
#endif
}
void wait_for_flash_ready(nrf_fstorage_t const * p_fstorage)
{
/* While fstorage is busy, sleep and wait for an event. */
while (nrf_fstorage_is_busy(p_fstorage))
{
power_manage();
}
}
static void fstorage_evt_handler(nrf_fstorage_evt_t * p_evt)
{
if (p_evt->result != NRF_SUCCESS)
{
return;
}
switch (p_evt->id)
{
case NRF_FSTORAGE_EVT_WRITE_RESULT:
{
} break;
case NRF_FSTORAGE_EVT_ERASE_RESULT:
{
} break;
default:
break;
}
}
NRF_FSTORAGE_DEF(nrf_fstorage_t fstorage) =
{
/* Set a handler for fstorage events. */
.evt_handler = fstorage_evt_handler,
/* These below are the boundaries of the flash space assigned to this instance of fstorage.
* You must set these manually, even at runtime, before nrf_fstorage_init() is called.
* The function nrf5_flash_end_addr_get() can be used to retrieve the last address on the
* last page of flash available to write data. */
.start_addr = 0x31000,
.end_addr = 0xFFFFF,
};
void update_bootloader_func()
{
volatile uint8_t iap_update_flag = 0;
uint32_t err_code = 0;
uint8_t i = 0;
uint32_t data = 0xF2000;
nrf_fstorage_api_t * p_fs_api;
p_fs_api = &nrf_fstorage_sd;
err_code = nrf_fstorage_init(&fstorage, p_fs_api, NULL);
APP_ERROR_CHECK(err_code);
nrf_fstorage_erase(&fstorage,bootloader_start_addr,1,NULL);
wait_for_flash_ready(&fstorage);
}
int main(void)
{
ret_code_t err_code;
uint32_t temp = 0;
update_bootloader_func();
while(1);
}
I don't have any Bootloader and My application flash range is 0x31000 - 0xF1ffff
After I build and download by IAR. Everything is OK. I can erase internal flash 1 block form 0xF2000
But If I click option -> Debugger -> Use flash loader and Override default .board file
I go to run the same source code. Erase action will cause Hardfault in below function
/* Erase flash page(s). */
static uint32_t erase_execute(nrf_fstorage_sd_op_t const * p_op)
{
return sd_flash_page_erase(p_op->erase.page + p_op->erase.progress);
}
Why? We don't have any idea how to debug this problem. Can you help me to try this problem using my source code?
Thank you.
John.
