Part Number: BOOSTXL-BUCKCONV
Other Parts Discussed in Thread: SYSCONFIG

team,

I'm trying to get BOOSTXL-BUCKCONV to work together with a f280049c launchxl following documentation. I feel i get everything right to the point when I run the project and shoud sense Vin at 0V then toggling the SW1 on the boostXL should get me my input supply voltage. but before and after the switch I get about 0.4V all the time. and obvisouly no Vout. please help

Olivier,

I'm currently looking into this, the primary owner of this kit is currently OOO so I will need a few more days to research. Appreciate you patience here.

Best,

Matthew

Matthew,

thanks sure. Are you looking at trying to duplicate on your side? I have a customer sync up next Monday, for which I would need to have this to work. Don't hesitate to plan a debug session if you dont have the buck converter boostXL handy. the issue arises so early in the process that it has to be a noticeable mistake that I do on my side.

We found that the default setting of this project/sysconfig is to use site1 booster pack headers for the compile. All the user guide's/examples assume use of site 2. I have filed a bug to correct the default setting. Picture below of the sysconfig GUI and the area of interest that need to be changed to site 2.

Best,

Matthew
