Dear Eric, Daniel,
I see. Indeed if the INFO section contains only "useful" data and not
"critical" data, then I can safely erase the device.
Sorry for asking silly questions, but though being an electrical engineer I
come from the analog side of the world. I guess cannot achieve the
mass-erase using the Launchpad-like FET, right? It has to be done with real
JTAG programmer? Even more (mspdebug manual page) from non-USB one?
Regards,
Kuba

All the data continuously generated in your IT infrastructure
contains a definitive record of customers, application performance,
security threats, fraudulent activity, and more. Splunk takes this
data and makes sense of it. IT sense. And common sense.
