This tutorial explains how to install the toolchain and build tools, see GNU toolchain for ARM Cortex-M and GNU make in the 'before we begin section. You may use GNU make from MinGW or Cygwin instead as long as you add the path to GNU make to your env. path.

You can run the build_all.bat script in the micro-ecc directory once you have installed everything (note that Git is required).

I assume it is failing at the pre-validation step (i.e., where validation of version numbers and signature takes place). You can place breakpoints in dfu_req_handling.c->dfu_handle_prevalidate to confirm. Alternatively, use the pca10040_debug project that has logging enabled by default, and check the log for error messages.

Thanks for reply,

I did nrfutil.exe keys generate private.key

nrfutil keys display --key pk --format code private.key --out_file public_key.c

And copy __ALIGN(4) const uint8_t pk[64] = { 0x46, ............... 0x31, 0xd6, 0x2c, 0x22, 0x79, 0x5e, 0x78, 0x6c }; to Project secure_dfu_ble_s132_pca10040-nrf52382_xxaa_s132

Hi, did you update the public key in your bootloader to one that corresponds to your private key? Note that we don't provide the private key used to sign dfu_test_app_hrm_s132.zip
