How to generate firmware's hash.

[andhakanoon]

Hello Everyone, 

I am a beginner

I am working on a project which requires authentication of the firmware , for this purpose i want to generate the hash of the firmware .

So while searching i cam across this function--> nrf_crypto_hash_calculate()  which uses source address and length, can anyone help me were i can find my firmware start and size of it,

nrf_crypto_hash_calculate(&hash_context,
                          &g_nrf_crypto_hash_sha256_info,
                          (uint8_t*)src_addr,
                          data_len,
                          m_fw_hash,
                          &hash_len);

Hi,

You can use the CODE_START and CODE_SIZE symbols defined in components\libraries\util\app_util.h for this purpose.

Best regards,
