how can i start OTA-Bootloader firmware update application for nrf51822 QFABB00 (0x004c)

[jignesh]

i am already use sdk10 and Eclipse gcc tool chain set-up.. but when i am programming on nrf51822. so, it's not work. also, it's working on nrf51422 QFACAB0(0x0071)..

GIVE ME ANY HEX FILE... FOR BOOTLOADER, FOR NRF51822

As i already answwered in your different topic, you are using nrf51822 with only 128kb rom and 16kb ram, and it is revision 2 chip. you should switch to revision 3 chip to use SDK10 and newest softdevice. But for development purpose you could try compiling single bank bootloader or modify dual bank to fit in your memory layout.

but i have no choice for change my chip. so, please any another way...

[Wojtek]

You can try using single bank bootloader, as i mentioned before.

[jignesh]

i can do it.. by change on linker file. and dfu_type.h file..
