Launchpad as external programmer

Recommended Posts

The upper limit for RST capacitor is 2.2nF.

Do you have a source for this information handy? I've been battling similar problems with the interesting twist being SugarAddict seeing kinda-sorta different behaviour on the exact same (production run) board. Smallest I tried was .1uF I think (also the LP schematics indicate LP uses 1nF, not really sure what was I thinking, but I'd like to read up on this now :)).

 

Yes. FET430 wire pinout(SBW) explain that ;)

BTW I have tested with 1nF capacitor too. Works ;)

It works (well, for me) without that cap too (used that as a workaround). My jumper wires are 8-ish inches.

This capacitor (C14 - 1nF) is part of LaunchPad. If you connect programming wires to connector J2 connected to socket, you not need it.

Of course, if You use J3 or mini - connector J4 then 1nF capacitor is recommended (but not absolutely must-have...).

The 1nF cap has nothing to do with programming. It is just there to prevent an MSP from resetting due to external effects like ESD. I never use it on a bread board, and of course it works, but I would always include it in a final design... a lesson I learned the hard way ;)

Well, I am trying about 3 days for the issue of programming of F5438A device... :x

I think this problem is also considered a hard-way-lesson for me ;)

I can also confirm that the Launchpad V1.4 and V1.5 will program external devices (F5510)... Even in CCS (No more Device not supported, etc...). Only drawback is that SBW is quite slow... I have also been able to program a few devices with 16" jumpers...

I have both of v1.3 and v1.4 version LP's and I have found a wiki page about updating eZ430.

I've updated my LP's using FET430 UIF and now both of LP's, programing F5x devices too fast.

And after the programming Flash(Quick Download in IAR, without Debug) the Reset button is works. In the older revision, I have to unplug and plug the LaunchPad for running the downloaded code.

I strongly recommend it ;)

Hello,

 

There is some good news from my side that I would like to share in this same context.

 

I have tested MSP430 LaunchPad to successfully program MSP430F5310, MSP430F5418 and MSP430F5438 over SBW!! :thumbup:

I would detail the setup in my blog.

 

These are all bigger microcontroller and have lots of features.

They are the ones I use to make embedded products at work.

Some of them can give a battery lifetime of 5years on 2.4G Wireless networks.

 

Well now I can use them at home too. Thanks to TI , MSP430.

And a Big Thanks to the 43oh Community :clap:

 

I have new board coming up that I have developed using MSP430F5310.

Hope that this would enable more advanced projects.

 

This is great News! Did it need any special procedures to get done?

 

regards,

--to
