i am using nrf52840 controller.
and in that i have mbe at 0x0000000 location.
i have two bootloader stage. that boot1 and boot 2.
boot 1 i am using to validate the bootloader 2 using signature verfication.
and once control reached to the boot2 then i want to verifiy the signature of my application and also want to check whether need to stay in dfu mode or should jump to application part.
For Boot2 i am using "nRF5_SDK_17.1.0_ddde560\examples\dfu\secure_bootloader" example code.
Can someone guide me to resolve this
No that part i have not tested with my key and signature. because previously i faced some issue while using "nrf_crypto_ecdsa_verify" this API for verification.
After that i contact with nordic team they suggest me to use "nrf_dfu_validation_signature_check" this one. but now i have issue with my hardware , it went bad. hopefully today will receive new hardware and then i will perform DFU operation using my public key and signature .
i have one more doubt but before that i want to test it on the hardware.
