USB-PD-CHG-EVM-01: TPS25750 Application Customization Tool still broken

Hello,

We will get back to you by next Monday.

Thanks,

Mike Emanuel

Hi, I have been having the same issue as Thomas: I generate a binary file in the TPS25750 Application Customization Tool, download the file and flash the EEPROM using the Aardvark. When I power cycle the board and connect the battery, I get the blinking fault LED. I use the USB2ANY to check the registers of the BQ chip, and the configuration is different than the one I set in the Customization Tool. If I manually adjust the BQ settings, it becomes possible to get PD working and to charge the battery.

My questions are as follows:
- Do you know what the timeline is for fixing the bugs with the Customization Tool?
- Is there an alternative way to generate the binary file? Is it possible for someone from TI to generate the correct binary given a specification?

Thanks for your help! Our company plans to use the EVM in one of our future products, so I hope we can get it working soon!

Boris,

This current target releae date for the GUI is Dec 9th.  We are addressing a few confiugration issues.

If you share the JSON file generated by the current WEB GUI, then I can generate a configured binary to get you working early next week,

Hi Chuck,

Thank you for your reply.

Here is the JSON file: {"questionnaire":{"version":"7.0.1.3","answers":[0,4,4,1,3,0,1,null,1,null,0,14.8,3,0.2,0.2],"options":{},"configID":"0000","vendorID":"0000"}}

If you can generate a binary for me, that would be great!

Regards,

Boris

{"questionnaire":{"version":"7.0.1.3","answers":[0,4,4,1,3,0,1,null,1,null,0,14.8,3,0.2,0.2],"options":{},"configID":"0000","vendorID":"0000"}}

Boris,

Attached is your JSON saved as a file and the corresponding full flash JSON.  

I have to do a lot of transposing of data, so if any of the values are off, please let me know.  It is likely a copy error on my part from the calculator to the developer tool.

Hi Chuck,

Thank you for the file. The only thing I can see that is different is the charge current, set to 1A. We can still use it though.

Is there a way to generate a more "advanced" binary? In this case, we would be interested in:

1) Setting EN_EXTILIM = 1. I want to set the input current limit to the BQ25792 via the external voltage divider and ILIM_HIZ.

2) Ignoring TS and leaving it NC, so setting TS_IGNORE = 1: The battery that I'm using has its own protection, so TS is not needed. Also, I would like to minimise component count as much as possible.

Could you generate one more full flash JSON with the following configuration: {"questionnaire":{"version":"7.0.1.3","answers":[0,4,4,1,3,0,1,null,1,null,0,16.8,5,0.2,0.2],"options":{},"configID":"0000","vendorID":"0000"}} . If it is possible to include the points above, that would be great!

Thanks again,

Boris

Boris,

We do not have a method to support the changes that you have requested in questions 1 and 2.  We only provide a basic control profile for the BQ25792 and do not have a method to update it currently.

If you have a MCU in your system that is connected to the I2Cs bus of the TPS25750, then I can help you with a method to allow you to update settings on the fly

I can generate the new Binary based on your JSON next week.

Regard,s

Chuck

Hi Chuck,

Thank you for your reply. We are considering adding an MCU for more in-depth programming, so any advice you could share will be useful!

I look forward to receiving the new binary.

Thanks for your help,

Boris

Boris,

I will be able to create the binary for you tomorrow.

Borris,

I just noticed I missed creating this for you.

I am in the middle of testing the new GUI release candidate today and I wont be able to address this until Monday.
