Re: [Mspgcc-users] Problems with erasing MSP-EXP430FR5739 and then Security fuse blown error
I had the same thing happen to one of my FRAM boards. I programmed a Launchpad to invoke the FRAM's Flash Boot-Strap Loader and give the Mass Erase command. It's worked on two boards that I am aware of: Directions and code are here: http://dbindner.freeshell.org/msp430/fram_bsl.html Don -- Systems Optimization Self Assessment Improve efficiency and utilization of IT resources.

Dear Daniel, Thanks a lot! I understand now better how this works. I will try to mass-erase and report to the group later on.

the offendig code is executed. It helps if it is not really the fuse but a code problem.

Re: [Mspgcc-users] Problems with erasing MSP-EXP430FR5739 and then Security fuse blown error
Hi Daniel, Thanks for the info. That sounds a bit better than the chip replacement (though I will try that if nothing else works, thanks Crazy Casta). Did you come across an instruction to follow this procedure? Can it be done with mspdebug? As far as I read this morning about BSL operations, the mass erase deletes both program and information data. Isn't loss of information data going to bring me more trouble? :) Best regards, Kuba On Tue, Nov 22, 2011 at 1:04 AM, Daniel Beer dlb...@gmail.com wrote: On Sun, Nov 20, 2011 at 02:34:05PM +0100, Kuba wrote: I am new to the list, trying to dive into the world of MSP430 and I already thank you for the great work around mspgcc/mspdebug.

Isn't loss of information data going to bring me more trouble? :) INFO is really just set aside flash. It isn't really all that special. At least that is true on the older parts, x1, x2, x5 families. I suspect that is still true with the FR parts but haven't looked. For example what is in one of the INFO sections for the 2618 is calibration constants. But these constants are determined by TI for 3.0V, such and such a frequency, and such and such a temperature. Usable for sure but not necessarily the ambient that one will actually be using the beast at. For example, we are using a 5438a and there are also calibration constants but we can't use them because we are running the chip at 1.8V, 38 degrees F, and 4 MHz. So the constants are crap for us. Bottom line is it depends on what is the INFO area. But most likely it won't hurt you. eric Best regards, Kuba On Tue, Nov 22, 2011 at 1:04 AM, Daniel Beer dlb...@gmail.com wrote: On Sun, Nov 20, 2011 at 02:34:05PM +0100, Kuba wrote: I am new to the list, trying to dive into the world of MSP430 and I already thank you for the great work around mspgcc/mspdebug.

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?
