Program ADKP service error

David2024 — Wed, 28 Aug 2024 08:24:51 GMT

Hi:

There is a HardFault error when I call interface HSE_ProgramAdkp() to set ADKP password, but there is no response, when stop, there is an HardFault error, the pHseSrvDesc and pAttr(debug key password) are all in on-cache, shows below:

from CFSR, it seems that there is a BussFault error in call (*(Gpt_pConfig[coreID]->Gpt_pChannelConfig))[ChannelIndex].Gpt_pfNotification();

but I think the address is correct, so why does this happend?

Because program ADKP is irreversible, that means I can only do this once in one board?

Hi @David2024

it sound like read-while-write issue.

ADKP is stored in UTEST:

But UTEST is in the same partition like code block 0:

So, it's necessary to take care about the synchronization as described in HSE FW RM:

And yes, ADKP is one time programmable only.

Regards,

Lukas

Hi Lukas：

Thanks for your detailed explanation, so that I need to put the command in RAM to avoid execute from flash block 0?

Yes, running the code from RAM should solve the problem. However, it won't be enough to put only HSE_ProgramAdkp to RAM because it calls other functions...

solution：

1. run code from RAM;

2. suspend interrupt;

hope this can help you.
