Error of nRF52832 memory map

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
