curtis63 5 Posted May 28, 2016 Share Posted May 28, 2016 I wanted to measure energy usage vi the Code Composer Studio's EnergyTrace feature. Documentation says I needed to get an MSP-EXP430FR5969. So I ordered one from Mouser and then noticed that the documentation on the Energia site said that revision 1.2 of the board wasn't suppported by Energia but that version 2.0 was supported. So, is there any way to update the board from 1.2 to 2.0 apart from just ordering an updated one? Thanks for your help, Curtis Quote Link to post Share on other sites
tripwire 139 Posted May 28, 2016 Share Posted May 28, 2016 That information on the Energia site looks a bit confusing to me. The MSP-EXP430FR5969 board has two different version numbers: One for the eZ-FET and another for the entire board. The version 2.0 board is the one that features EnergyTrace, but the version of the eZ-FET on that board is 1.2. I think the Energia site is saying that if you have the board that says "eZ-FET Rev 1.2 with Energy Trace" then it's probably a V2.0 board. When that documentation page was written Energia didn't support this new board, only the old one without EnergyTrace. This means there isn't a upgrade path as such, because the board with the V1.2 eZ-FET is the latest version. I don't know how long ago that documentation was written, so I'm not sure if it's still correct. Have you tried using Energia on the board you have? Quote Link to post Share on other sites
spirilis 1,265 Posted May 28, 2016 Share Posted May 28, 2016 IIRC the v1.2 "board" isn't supported by CCS either because it's not supported by the MSP Debug Stack software, which also explains why Energia doesn't support it. So you're sure it's a MSP-EXP430FR5969 "v1.2" board? Quote Link to post Share on other sites
tripwire 139 Posted May 28, 2016 Share Posted May 28, 2016 Did TI use V1.2 as a "board" version number for MSP-EXP430FR5969 previously? If so, what's the version of the eZ-FET used on that board? Quote Link to post Share on other sites

IIRC they used 1.2 and the ezFET may have been 0.9 or something. Memory is rusty here though. Quote Link to post Share on other sites
greeeg 460 Posted May 29, 2016 Share Posted May 29, 2016 I went and dusted off my old FR5969 boards. Here they are. From my memory they only ever sold the two? but maybe they have a newer one. The left one is the original with experimental silicon not intended for production use. After they released the production variant of the IC they removed this one entirely from the ezFET code, meaning you cannot debug/program it. The ezFET will still work fine programming external chips. You can check this quickly, the experimental silicon has X430 instead of MSP430. Secondly there are 2 model numbers for each PCB, the Launchpads them selves, 1.6 and 2.0. and then the ezFET 1.0 and 1.2. I very much doubt that mouser still has inventory of v1.6 launchpads with the ezFET 1.0, this was replaced by rev 2.0 with ezFET 1.2 about 2 years ago. TI even offered free replacement upgrades for everyone who bought them at the time. spirilis and tripwire 2 Quote Link to post Share on other sites
curtis63 5 Posted May 29, 2016 Author Share Posted May 29, 2016 Ah!!! Thank you everybody. You are right. I was looking above the JTAG socket and saw rev 1.2. However, the board rev is 2.0 on my board as displayed on the upper right hand side of the board, as pictured in the post above. Thanks for clearing that up for me. I really appreciate it !! tripwire 1 Quote Link to post Share on other sites
