DFU Bootloader Porting from SDK 6.0.0 to SDK 6.1.0.

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.

Over flow error was due to allocating more memory of RAM in make file, I solved it, but didn't help much, so I later tried to port the Dual Bank Project to Single bank by replacing the .c files from Single bank as you advised, Worked fine but not as expected, Total flash Size is 256Kb, in that ->88K is for S110 (v7.1.0), ->Bootloader of 40KB(altered the Bootloader Start Address to 0x00036000), ->To store Bootloader settings 1 KB is allotted, ->Application Data of 4KB(Assumed). So remaining space is for Application ie, (256 - (88+40+1+5) ) which is equal to 122K, which means I can load the application of max size 122K, I have 2 application files of size(BIN File Size) 55474 bytes and 59300 bytes, 55474 bytes size file was successfully getting uploaded where the other (59300 bytes Bin file) was not. Is it that still I am using Dual Bank mode DFU, I didn't include the Dual Bank c file in make file. So why the 59300 bytes Bin file didn't successfully get uploaded ?, Is there anything to change in the DFU Project? or is there anything to change in the application part?.
