Dat file problem in dfu zip pack

[Ferhat]

Hi

Im trying to generate dfu zip package.

Im working on ready hex and zip files in nRF5_SDK_13.0.0_04a0bfd

In examples\dfu\ble_dfu_send_hex\test_images_update_nrf52832, i can load zip file (dfu_test_app_hrm_s132) by nrf toolbox (mobile app) And dfu_test_app_hrm_s132.hex works when loading with nRFGo.

So im trying to make zip file from dfu_test_app_hrm_s132.hex I see bin file is same but dat file differs.

I used nrfutil.exe from python and master control panel.

For example; nrfutil pkg generate --hw-version 52 --application-version 1 --application dfu_test_app_hrm_s132.hex --sd-req 0x98 --key-file private.key dfu_test_app_hrm_s132z.zip

nrfutil pkg generate --hw-version 52 --sd-req 0x98 --application-version 4 --application dfu_test_app_hrm_s132.hex --key-file private.pem dfu_test_app_hrm_s132.zip

I tried many thngs and confused.

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

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

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.

Ok, Can you help me how to run make file in "external\micro-ecc\nrf52_iar\armgcc" I downloaded MinGW and Cygwin64 but i didnt understand how to run Makefile

I didnt understand what to do GCC compiler tootcchain for ARM

Faulty: micro_ecc_lib_nrf52.a
