Hi,all
I have a problem about the lockbox with the custom board.
I can enter into the secure mode by using the emulator without any problem.
if generate the ldr file and program to the inner-spi-flash,the led can blink,and the secure authentication goes fail.
Could someone tell me the reason,thank you.
best regards!

 

// custom board.
// CPU: BF512F,REV0.1
// ldf: USE_DATA_A_CACHE,USE_SCRATCHPAD_STACK,USE_SCRATCHPAD_HEAP, secure overlay
// initcode: see init dir
// didn't use the preboot para. in the otp memory and the public key have write into the otp correctly.

 

// the problems are:
// 1. the system can enter into the secure mode by using the emulator without any problem.
// 2. if generate the ldr file and program to the inner-spi-flash,the led can blink,and the boot seems correct.
// 3. it seems can't enter into the secure mode, and the authentication was failure.

// my questions are:
// 1. the preboot page int the otp was necessary if I want to use the lockbox?(I use the init code)
// 2. why the boot was ok, but the secure authentication goes fail?
// 3. the default ldf was changed by I for target board use.it can effect the secure authentication?
// 4. does the hardware can effect the result(system can boot cottectly)?
