Remote DFU: Operation Failed Error in Secure OTA

[Nilesh Bhavsar]

Hi,

I am trying to secure OTA in nrf51822 board.

For that trying to build bootloader file available in SDK 12.2.0 version at location nRF5_SDK_12.2.0_f012efa\examples\dfu\bootloader_secure\pca10028_debug\arm5_no_packs. But it is building perfectly and give me error of micro_ecc_lib_nrf51.lib file not found error.

i have already installed 4.9-2015-q3-update of the GCC compiler toolchain for ARM and put uECC.h file in external/micro-ecc/micro-ecc file.

Dear Sir,

As per your Suggestion, i am trying to find out my problem using nRF Logger application. In that i found Remote DFU Operation failed error. I have airedy install latest version of the nRFconnect Application.

I am using external tool for flash programming in keil. In that, Command is nrfjprog.exe and Arguments is --reset --program "#H".

My internal Ram setting for bootloader: [Read/Only Memory Areas: IROM1- start: 0x3AC00 Size: 0x500][Read/write Memory Areas: IRAM1- start: 0x20002C00 size: 0x5380]

As of now i am trying to simple example program which is available in SDK at examples\ble_peripheral\experimental_ble_app_buttonless_dfu\pca10028\s130\arm5_no_packs.

My internal Ram setting for Program: [Read/Only Memory Areas: IROM1- start: 0x1B00 Size: 0x25000][Read/write Memory Areas: IRAM1- start: 0x20001FE8 size: 0x6018]

Please suggest me.
