RE: bootloader DFU buttonless

Cy — Thu, 31 Dec 2020 19:25:24 GMT

Having gone through the instructions again carefully I have had success utilizing these tutorials. I have made a couple of changes:

1. in the sdk.config I set the

NRF_BL_DFU_ENTER_METHOD_BUTTONLESS 1

2. In Nordics tutorial I see a difference the format private.key or private.pem. I used gamnes private.pem format to create the application zip.

3. both the secure bootloader buttonless soft device and the ble_uart application use the SD 7.2.0, and therefore the sd -req is 0x101.

I primarily followed the Nordic based tutorial based on SDK12 with the above changes.

I am in need of some help, love to chat most often, but I have a problem I need to solve. I am working with the armgcc toolchain within SDK17.02 with command line and nrfutil. I want to create a secure bootloader within the 17.0.2 SDK and the applications would also be developed to first run standalone with the same SDK.

I have tried to follow the two tutorials above to fit the SDK17.0.2, but the tutorials are written for SDK15.0.0 and I think I have some things right, but obviously I have some things wrong.

Has anyone ported the bootloading tutorials into SDK 17.0.2 and if you were successful do you have any suggestions? Thank you!

Hello,

You can also find the FWID from the Softdevice release notes ("nRF5_SDK_17.0.2_d674dde\components\softdevice\s132\doc\s132_nrf52_7.2.0_release-notes.pdf"). FWID for s132 v7.2.0 is 0x0101.

I wrote the table many moons ago based on this github link; it doesn't actually cover v7.2.0, I just used the sd call to find out what was used in that case.

Where did you find this list, SD specifications, where?

Thank you! I have tried it both ways.

In case this helps, I found the SD v 7.2.0 was 0x101, not 0x102:

    {0xB7, "s132_nrf52_6.1.1"},
    {0xC2, "s132_nrf52_7.0.0"},
    {0xCB, "s132_nrf52_7.0.1"},
    {0x101,"s132_nrf52_7.2.0"},

I have been following gamnes' tutorial located at github. The batch files utilize nrfutil to generate the hooks between an application and the bootloader. I have utilized the armgcc command line tool chain to program the dfu secure_bootloader pca10040_s132_ble_debug. The system can be identified on the PC through nRFconnect and connect to the USB dongle PCA10059 loads a fw.zip and begins to transfer, or validate, but the debug output, text included below, line 52 SD req not met.

I have scrounged around the dev zone and found that the SD req for the s132_nrf52_7.2.0_softdevice.hex is 0x102 and 0x101 and edit this inside the batch file 03 inside gamnes's tutorial which creates the FW.zip with SD merged to app, and 03b without SD merged.

echo "## Creating a FW.zip package that can be used to update the FW on the DK"
nrfutil pkg generate --application app.hex --application-version 1 --application-version-string "1.0.0" --hw-version 52 --sd-req 0x102 --sd-id 0xA8 --softdevice s132_nrf52_7.2.0_softdevice.hex --key-file private.pem FW.zip
echo.

One thing to note is gamnes' 03 batch will not find s132_nrf52_6.0.0_softdevice.hex, when the batch file calls:

echo "## Creating a FW.zip package that can be used to update the FW on the DK"
nrfutil pkg generate --application app.hex --application-version 1 --application-version-string "1.0.0" --hw-version 52 --sd-req 0x101 --sd-id 0xA8 --softdevice s132_nrf52_7.2.0_softdevice.hex --key-file private.pem FW.zip
echo.

I have set the S132=s132_nrf52_7.2.0_softdevice.hex within the batch, but I wonder if the nrfutil is the latetest version on my machine?

version 6.1.0
