Hi.
I modified the fstorage example to create the project.
I split Flash into three areas as shown below.
*Flash Area(0x26000 ~ 0x2ffff) : Bootloader
*Flash Area(0x30000 ~ 0x4DFFF) : Application 1 (written 34858 byte)
*Flash Area(0x4E000 ~ 0x6BFFF) : Application 2 (Empty)
I have written code to copy the App_1 area to the App_2 area for testing, but it doesn't work.
nrf_fstorage_write return 0x10(NRF_ERROR_INVALID_ADDR).
static void start_Update_Firmware(void) {
flash_Erase(fData.tFirmPage);
for (uint8_t wSEQ = 0; wSEQ < fData.tFirmPage; wSEQ++) {
flash_Read(wSEQ, rFData);
flash_Write(wSEQ, rFData, sizeof(rFData));
}
}
