I am currently migrating from F2012 to FR5720.
My interpretation of the MSP430F2012 datasheet leads me to believe that there is no bootstrap loader code in this device and that when the JTAG fuse is blown the firmware and all internal memory is no longer accessible. Is this true or false?
The MSP430FR5720 has a bootstrap loader and I need to provide optimum security for the device firmware.
I know that there is a disable code and various methods of password protection but I have been given this link http://events.ccc.de/congress/2008/Fahrplan/attachments/1191_goodspeed_25c3_bslc.pdf that indicates the BSL can be hacked.
Can you comment on this BSL hack?
Is there a way of erasing or corrupting the BSL code?
What are the security measures in place or available for this device?
Any direction here would be very much appreciated.
