Error of nRF52832 memory map

Youngjun

Hi,

I was in a strange situation using nrf52832QFAA.

I'm using nRF52832 and nRF52840 evaluation board.

When i download code using Programmer(nRF Connect), the memory map of my nRF52832QFAA is full of 1byte code.

Does anyone have this kind of situation?

Regards,

Youngjun.

    Hi Youngjun,

    Which firmware did you flash on your device ? 

    Have you tried to read out the flash content after you flashed ? 

    I would suggest to try testing with nrfjprog.exe tool to erase, program and read flash content in addition to the nRFConnect Desktop tool. 

    If you simply flash a normal example from the SDK do you have the same issue ?

    Hi Hybg Byu,

    I tried read out memory.

    If i read the memory, it comes out as above.

    I used dfu and softdevice(6.1.1).

    I found 10ea of these symptoms on my chips.

    I used nrfjprog.exe (nrfjprog -f NRF52 -–recover).

    But, the memory didn't erase.

    I tried to clean nrf52832 using nrfjprog, and download softdevice using uvision.

    I got below message.

    Hi Youngjun,

    Please use nrfjprog.exe to flash the softdevice and the application. I attached the hex files that you can test. 
    Please call the following scripts on the nRF52832 DK: 

    nrfjprog --eraseall
nrfjprog --program s132_nrf52_7.2.0_softdevice.hex
nrfjprog --program ble_app_hrs_pca10040_s132.hex
nrfjprog -r

    It should blink and advertise after flashing. 

    If error occurs, please take a screenshot .

    ble_app_hrs_pca10040_s132.hex

    4760.s132_nrf52_7.2.0_softdevice.hex
