The dfu_dual_bank.c is a part of the bootloader, which is a separate project that you must compile and flash to your device, see this Infocenter page. You need to replace dfu_dual_bank.c with dfu_single_bank.c in the bootloader project, not in the application. The files you add in your application only provides the ability to jump to the bootloader which actually receive the firmware image and replaces the old firmware with the new firmware.

ya i am followed the same step as u mention. but in that step they are not selecting dfu_single_bank.c file or dfu_dual_bank.c file. Only bootloader_util_arm.c ,dfu_app_handler.c, ble_dfu.c these three files. Then how it work as dual bank dfu

You should not add dfu_single_bank.c file to the ble_app_hrs example if you want to add DFU support. If you want to add DFU support to an application then you need to follow the steps given on this Infocenter page.

Ok, then just edit the following line in the Makefile under C_SOURCE_FILES += \ from

$(abspath ../../../../../../components/libraries/bootloader_dfu/dfu_dual_bank.c) \

$(abspath ../../../../../../components/libraries/bootloader_dfu/dfu_single_bank.c) \

I am using GCC compiler i referred ble_app_hrs example code to implement dfu in my application . single_bank or dual_bank which one they are using in ble_app_hrs example code

You can convert a dual bank bootloader to a single bank bootloader by replacing dfu_dual_bank.c with dfu_single_bank.c. Are you using Keil or gcc to compile your projects?

Thanks for ur response. That i know i can flash ota file size maximum 74kb. But my file size is 112kb how its possible to flash this large file through OTA.

The S110 v8.0.0 needs 0x18000 bytes of Flash and the bootloader should start at 0x3C000, which means that you have 0x3C000-0x18000 = 0x24000 bytes = 144kB left for the application. The application space will be divided into two banks of 72kB, i.e. the maximum application size is 72kB. Therefore, an application of only 58kB should not be an issue. Can you upload the hex file and the zip file of the application`?

i think issue is , now i am using dual bank DFU, in dual bank dfu we cant able to flash large files. so instead of dual bank i want to use single bank dfu. pls tell me how to add single bank dfu.

in my project have both dfu_dual_bank.c and dfu_single_bank.c file

i am using GNU arm eclipse software using SDK v.10 and Softdevice S110 s110_nrf51_8.0.0_softdevice.hex

Which SDK and SoftDevice version are you using? How did you create the firmware image ( i.e. zip file) you used to perform DFU? Can you upload the the zip file?
