ANT DFU-OTA Update Fail

[Roshan007007]

Hello,

I am trying the ANT-OTA DFU Update using an ANT Stick and the nr51422 pca 10028 board. The ANT Updater shows that the Image Upload is completed. I am uploading the s210 OTA Tester Application. But the application is not being loaded because the ANTWare II isn't detecting the ANT broadcast from the board. Also, the size of the application, when seen from the nrfgo Studio stays the same. I'm using the SDK 10 version.

File_before_OTA.hex : This is the Hex when the experimental_ant_bootloader is loaded on the board.

File_after_OTA.hex :This is the Hex after the ota_tester is loaded on the board via OTA Updater 1.4 (via application bar) .

File_after_BootloaderOTA.hex :This is the Hex after a custom file with boootloader is loaded on the board via OTA Updater 1.4 (via bootloader bar) .

nrf51422_xxac.hex: Application to be uploaded via OTA Updater.

Thank You.

Hi Roshan,

Sorry for the late response.

We found that it was a bug that if you enable "Enable softdevice protection" when flashing the softdevice in nRFgo Studio , then the DFU bootloader won't be able to start the application.

So could you please test flashing the softdevice with the option "Enable softdevice protection" unchecked and let me know the result ?

afterOTA.hex

Bootloader: bootloader.hex

@Roshan: It's a little bit strange. You sure you haven't modified the bootloader ? And you are using the latest OTA Updater, which is version 1.4 ?

You can update the hex file in your question, please click edit and add the file. I would suggest to get a hex file before you do DFU (when you only have softdevice and bootloader) and then after you do DFU. Also maybe send me a hex file after you do DFU with the setting that work for you (using the bootloader textbox)
