Hello.

kmh48301_0-1600040669058.png

this is from RM 36.4.4.1.4.4 (820p)

 

"In the secure state, the MCU limits access to FTFC module resouces."

In this papragraph, what does exactly mean "limit access to FTFC module resouces"?

 

I don't rember why. but somehow I understood in the secure state, 

All FTFC commands won't be excuted.

 

But my coworker thinks "no".

 

And I can't check this out because I worry board is locked.

 

Please help me

 

 

Thansk

Best regards,

phillip

Hi Phillip,

it can be explained by this description:

So, the restrictions are related only to SWD/JTAG access.

Regards,

Lukas
