Original question:

TPS25750: Source mode. GPIO direct access.

TPS25750: Application Customization Tool doesn't generate consistent binary (bug)

Part Number: TPS25750

Dear TI team,

After pulling my hair on some strange bugs (eg : https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1294435/tps25750-source-mode-gpio-direct-access/4913389#4913389)

I've noticed some strange behavior from your GUI TPS25750 Application Customization Tool 7.0.4.7 (I made sure to download again everything, to be up to date).

If I setup my config from the defaut EVM choice on question 1 (not selecting another choice), or if I select another choice before selecting again the Source/SinkTPS25750D/BQ (EVM config), the generated full-flash binary differs (sometimes, quite a lot).

If the config selected in the end is the same, shouldn't it generate the same binary ? And which one is the good one ??

Maybe you should look into that. I think the thread I linked above is because of that, I've selected the Source/Sink config after having selected a sink-only config, and some of the sink-only config remained so my TPS couldn't switch to source.

Here are some test configs and binary I've done to compare :

source_sink.rar

Feel free to contact me if you need more info.

Thanks and Regards,

Richard

    Hi Richard,

    Thanks for the feedback, let me look into this on our end. If this is the case, it does seem like a bug.

    The project configuration when selecting the initial project configuration is likely the "good one". The safest option when generating fresh projects is to reload the page.

    Thanks and Regards,

    Chris

    Hi Chris,

    Thank you for your answer, that is roughly what I concluded, going from fresh config, straight to what we want, has the best results and works as it should.

    We are progressing forward with our project, slowly, but I hope we'll manage to get a fully working configuration soon.

    We do work a lot with TI chips and need support from time to time, sometimes for troubleshooting, sometimes just for inquiries about a specific feature we are looking for. Instead of opening a thread here every time, is there a contact we could have, like a FAE, that could help us more directly ?

    You can close this thread if you want, now you are aware of it, or keep it open for issue tracking.

    Have a wonderful rest of the day,

    Thanks and regards,

    Richard

    Hi Richard,

    I appreciate the feedback. We are currently working on updating the GUI sometime this year and hoping that will solve some issues we have been seeing with this one. I spoke to a member on the team, and this issue was seen before and should already be fixed in the new version.

    We'll reach out to the local sales team and see if they can get into contact with you.

    Thanks and Regards,

    Chris
