TPS25750: task reject when period read from i2cm

Walker Wei

Part Number: TPS25750
Other Parts Discussed in Thread: BQ25792, BQ25790

We are using tps25750 + bq25792

I want to period check the bq25792's REG[0x1b]

As the logs below, "task reject" will happen after read some time, it seems like the bq25792 will enter suspend mode or something like that after booting up awhile.

Could you help to confirm?

Hi Jacob:

Thank you.

"...give us until ..."

You mean wait?

OK.

Hi Wei,

Yes please wait. I will have another engineer cover for this thread. Please ping us by Friday morning if you don't hear anything.

Wei,

We have identified this as a bug in the current code release and have a patch in place, but not yet released.

If you can provide me with your JSON from the export function in the configuration GUI, I can build a binary for you with the patch in place.

Regards,

Chuck

Hi~Chuck:

Well ,thank you, it's very kind of you.
We currently need 2 modules. One support PD 20V max, another one support PD 15V max.
Both are sink only and 2s battery.
Please build based on the attachments.
Thanks again.

So could you please provide the release date?
Some battery charger configuration parameters may be changed again because of our productions are still in developing.
I mean if we want to customize some parameters before the release date, should I send you a private message to get the full flash binary?

Thanks Wei. I will be able to work on this on Monday 3/7

Hi~Chuck:

Sorry to bother you.

Any updates please?

0 Chuck Branch over 3 years ago in reply to Walker Wei

TI__Mastermind 32661 points

Wei,

I am working with a new release candidate gui that is supposed to address one of these failures and if it works, you will be able to generate updates on your own without me doing it with our development GUI.

Chuck

Thanks.

Will there be a notification when the release is done?

I've found the TPS25750 Application Customization Tool is updated in 2020.3.7, but the version is still 7.0.2

gcruntime is updated to ver10.0.0

So that means I can use them by now?

0 Walker Wei over 3 years ago in reply to Walker Wei

Prodigy 150 points

I have used the TPS25750_Application_Customization_Tool-7.0.2.setup-win_10.0.0.exe and gcruntime-10.0.0-windows-installer.exe to install

But the tool can not be lunched. Have you tested before release?

0 Chuck Branch over 3 years ago in reply to Walker Wei

TI__Mastermind 32661 points

Wei,

This was tested, so you should not see this issue.

I am passing this ticket over to our GUI team to help you get it running and he will pass it back to me once the GUI is operational.

Chuck

Hello~GUI team:

Really need help here.

I have installed TPS25750_Application_Customization_Tool-7.0.2.setup-win_10.0.0.exe and gcruntime-10.0.0-windows-installer.exe in 2 PCs, one is win10, the other is win7.

But there is nothing happend when I clicked the launcher.exe

Please give me some advise ASAP when you see this message. We really need this tool running. This issue has been blocked nearly 2 weeks.

Hi~Chuck:

The development GUI tool can not be lunched, so I use the web GUI tool insead.

But the i2cr issue still happen.

If you have fixed this issue, so I guess maybe the binnary generated by web GUI is incorrect.

So could you help build the binary please?

The json.zip is already uploaded, please check the history comment.

0 Chuck Branch over 3 years ago in reply to Walker Wei

TI__Mastermind 32661 points

Wei,

The GUI team is planning to deliver me a GUI to test late this evening. I will use it and your JSON to create a binary for you and we will release the updated GUI as soon as possible.
