    Hi,

    BLOCKED state is state of device before security initialization is done and device goes into this state after every reset. Apart from this, DCSM and hence the device goes to BLOCKED state if any of the zone's CSM password gets loaded as all 1's from USER OTP. 

    Thanks & Regards

    Hi,

    Can I use RAM OPEN function to access a inaccessible RAM sector which is configured by OTP.GRABRAM?

    No. The RAMOPEN will not open any inaccessible RAM which is configured through the GRAMRAM OTP config. 

    Also, I would suggest to kindly open a new thread if there is a related question. There is high probability that your query may go unanswered as the current post is already resolved and closed,  

    Thanks & Regards
