DFU Bootloader Porting from SDK 6.0.0 to SDK 6.1.0.

[Raghu GS]

Hi,

I want to add DFU OTA feature for my project, I use SDK 6.1.0 and S110 7.1.0, I found a sample Bootloader code for different version of SDK (SDK 6.0.0), from Github [https://github.com/NordicSemiconductor/nrf51-dfu-bootloader-for-gcc-compiler] , The changes I have done is changing the board (to PCA10001) and changing the I/O's, but it seems to not even advertise, finally found that Pstorage register function returned "invalid Parameter Error" , so requested extra bytes(~2 bytes) of memory and the device was advertising as DFUTarg, but when I select my application hex file, uploading status goes halt, and DFU Timeout occurs and gets disconnected, Is there anything changes to be made to port to SDK 6.1.0 and also I need it to be ported to support Single Bank mode, How is it done, is there any procedure to be followed to port. I use Eclipse IDE, nRF Tool Android app.

Hi Raghu,

I assume you have updated the makefile to include the dfu_single_bank.c instead of the dfu_dual_bank.c. Anyway, I have tested and made a project based on the 2 examples on Github, please test and let me know if it works. The project is attached in the answer.

nrf51822_v6.0.0 - GCC_Bootloader_singlebank.zip

Thanks for the time working on that, I correctly included dfu_single_bank.c in Makefile, I was using hex file of my application, where sometimes nrf Tools Android App(Version 1.15.1) was not accepting all time, later tried with BIN files of the same project and was taking all time without fail and was uploading the application successfully, also tested with the max size of ~127KB application size, and was OK. Thanks for your assistance.
