nRF52810 Secure BLE DFU on IAR - not connecting

skhan80

Dear all members,

I understand that Secure BLE DFU official support is only for SD132, but I am developing a product for nRF52810 which can only run SD112 and I want to be able to update the application via BLE DFU (SD and Bootloader update requries dual bank and there is not enough memory on 52810). I am currently developing on an nRF52832 Development Kit emulating an nRF52810, running SoftDevice 112 v5.1.0, and using the IAR IDE. 

I am trying to change the IAR bootloader_secure_ble example in SDK 14.2 to work on the nRF52810 based on the following link: https://devzone.nordicsemi.com/f/nordic-q-a/27185/52810-how-to-use-dfu

So far I have failed. I have mimicked the link answer exactly and changed the 3 files. The example compiles, and runs (I see "Waiting for events" in Debug mode). The DK advertises as DfuTarg in the Nordic nRF Connect and nRF Toolbox. But when I try to connect to the DK using nRF Toolbox, it hangs and finally says "Error: Device disconnected unexpectedly." The J-Link RTT Viewer shows no new messages. I don't understand why this is happening. I assume that if the link says that the 52810 DFU works for Keil, SES, & GCC then IAR should as well. Can anyone help?

Thank you,

Saad

    Hi Saad,

    I've ported the 52832 bootloader project in SDK 15 to the nRF52810, please see attachment below. Hope this helps.

    Some notes:

    • DWARF format was changed from version 4 to 3 for the uECC build to make it compatible with IAR(build settings will be updated in a future SDK release).  Format version is set by adding "-gdwarf-3" to the list of compiler options. 
    • IAR linker settings were updated to reflect new memory layout
    • Added some ifdefs to comment out API calls not supported by s112 , code changes are listed in the diff file included in attachment.

    Edit:

    , I've updated the example to include support for GCC and SES. This has been done manually, so there's a chance that I have overlooked something.
