[vineet]

Hi,

I am working on nrf52832 and using SDK 16.

I try to debug the ble_app_buttonless_dfu example, which give error on line 853 in main.c.

err_code = ble_dfu_buttonless_async_svci_init(); this function giving error 4.

further debug inside this function get to know below function giving error

ret_val = nrf_dfu_svci_vector_table_set();

getting error number 4 here.

current memory segment value is mention below

FLASH RX 0x0 0x80000;RAM RWX 0x20000000 0x10000;uicr_bootloader_start_address RX 0x10001014 0x4

please suggest me how to fix this issue.

Hello,

The function is responsible for configuring the async SVCI interface to the bootloader but will fail with the error you mentioned if no bootloader is present.

Hi Vidar,

Thanks for reply.

What do you mean about "no bootloader is present", shall I need to download bootloader separately, if yes please let me know the thing what I need to do so I will able to configure the asyn SVCI interface for bootloader.

Thanks & Regards

Hi Vineet,

Yes the bootloader is a separate FW image. This is covered in the  Getting started with Nordic's Secure DFU bootloader, a step by step guide , see section 1. Combine application, bootloader and softdevice image - Bootloader setting and 3. Buttonless DFU 

Best regards,
