Hello,

I have some questions regarding OCDS

1 - I understood that the Debug System is disable by default and in case  I enable it, it  is mandatory to insert a password,  is that correct  ?

2 - The password mentioned is it valid ony for debug puposes or also blocked me to reflash the uC ? I meant I CANNOT flash a firmware again  in case I lost the password ? If I lost the password the uC is bricked ?

3 - I understood that the advantage of BROM and flash OTP is that is those are the only way to prevent  my code to be ovewriten, for instance a critical part of my boot, is that correct ?

Thank you so much in advanced,

Antonio

Hi,

1. Correct
2.Correct, if you have some other way that will take care of flashing through Application firmware then you can, provided you haven't enabled RPRO bit of pFlash.
3. BROM can't be flashed nor erased by user. Understanding about OTP is correct.
