    Unlocking flash after security is enabled.

      Hi,

         

      I need to re-flash devices which have the security activated. How can I erase the flash of an MB9BF321K after I have set the security to active (0x00100000 to 0x0001)? 

         

      Segger J-Link isn't capable of erasing it. The SWD interface seems to be blocked completely by this security feature.

         

      The USBDirect software has the erase functions disabled. From older screenshots it seemed that this function was available before but now has been removed for some reason...

         

      Any ideas?
