problem testing DFU functionality w/SDK14 SoftDevice v5

[Allen]

Hello,

I am trying to update our application with DFU support but it will not work for me. One of 2 things happens:

1. Programming the bootloader and softdevice by programming the hex image bootloader_secure_ble/hex directory. Then I download the application using Keil. It appears the bootloader gets erased. This appears to be the case because in nrf_dfu_svci_vector_table_set(), NRF_UICR->NRFFW[0] == 0xFFFFFFFF
2. Using nRFgo to program the bootloader, softdevice and our application, it powers up into the bootloader not the application.

How can I test the DFU integration in our application using the bootloader images provided?

Thanks

Hello ajc

Please try to follow the DFU example documentation here. Are you able to correctly program and update your application when you follow the example?

Best regards
