Package for BLE Secure DFU bootloader step by step guide for S132 PCA10040

[inghowe83]

Hi There,

I was trying to understand the step to create a test app for dfu bootloader update via BLE for PCA10040. Below is the documentation I read.

http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v14.2.0%2Fble_sdk_app_dfu_bootloader.html

I'm interested to further explore the Testing part by create my own firmware package for testing, and I not sure which example I could use for putting public key and generate the programming zip package.

Can I use the below package?

By the way, I tested flashing the dfu bootloader firmware which i have my public key place before generate the hex file.

Guide: https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk52.v0.9.2%2Fbledfu_example_running.html

Example: 

I received flashing error as below.

Mind to share similar document as the following link for S132 PCA10040? It would be much appreciated.

Hi Bjørn Kvaale

Thanks. But where can I obtain Jlink v6.12a? The seggar website only provides the latest Jlink.

By version, click on "older versions" & you should easily be able to find the correct Jlink to download.

Hi Bjørn Kvaale

I can flash the hex now but the ble blinky cannot detected/appear if I flash using the generated hex file(it only works if I use Build and Run only). Mind help test out my generated hex file? Thanks

Just tested your hex file. I received a weird error when I flashed the softdevice with nrfjprog (ERROR: The file specified could not be open for read.). Where you able to flash the softdevice to your device with nrfjprog?

The steps I took were: nrfjrprog --eraseall (erases all flash, including UICR)

flash sdk 14.2 softdevice with nrf go studio

nrfjprog --program secure_dfu_ble_s132_pca10040.hex --verify

Then, LEDs 1 & 3 turned on, indicating that the device is in bootloader mode. The nrf52 dk also started advertising as DFUTarg on nrf connect, so it seems everything worked like it should. If you are having difficulties with this, it seems there might be something wrong with nrfjprog (like mentioned before, maybe you are using the wrong JLINK version).

Hi Bjørn Kvaale

Thanks for the update. I have check my jlink version. BLE DFUTarg still not working, do you think its caused by segger project compiler setting? I use the default DFUTarg project.

Here is the programming step

nrf Connect on my phone with BLE enable, no DFUTarg appear.
