TPS65987D: TPS65987EVM: FTDI firmware

Hi Emma,

Thank you.

In my understanding, The TPS6598X-CONFIG GUI is for page 10, U5 MX25L8006EM1I-12G In slvubo9a.pdf, not for U7, 93LC56BT.

May I know where can I download the firmware for U7, 93LC56BT, in page9 of slvubo9a.pdf ?

Hi Emma,

Thank you, I can importTPS65987D settings via Aardvark. But failed at Export Settings to Device RAM, see below pictures:

May I know how to fix this problem?

Hello,

Your photos did not attach. What do you mean export settings to device RAM? 

Thanks,

Emma

Hi Emma,

thanks for quickly response, I uploaded the pictures, could you please check again?

Hi Jack,

Can you explain what you are trying to accomplish with this feature? I think that there is a different method you should use if you are trying to configure your device. I can better help point you to this if you break down what you are trying to do.

Also, can you please try I2C1 and let me know your results? 

Thanks,

Emma

Hi Emma,

I tried to verify the settings for TPS65987D are good or not.

I will try I2C1 later.

thanks,

Jack

Hi Emma,

I2C1 has same result, see below picture.

One more question:

Which document can show the flash allocation?

In TPS659xx_Application_Customization_Tool_User_Guide.pdf, I found it mentioned "low-region" of flash, I would like to know detail.

thanks,

Jack

Hi Jack,

We normally update the firmware using Binary > Flash from current project. 

Your problem may be coming from your 0x3 register. The PD controller should be APP during normal functions. BOOT means that the PD controller is still in its boot mode. Can you try flashing the firmware through the method I mentioned above and let me know your result?

In case you would like more information on our GUI, we have a three part video training series on it:  

Thanks,

Emma

Hi Emma,

I tried:

1, Flash erase, then The PD controller become APP, see below picture

but Export settings to Device RAM still failure!

2, Create a new project with default setting, update the firmware using Binary > Flash from current project

then the Mode Register 0x3 is: BOOT.

3, I used Flash read, and upload the file.

Could you please try in your side with this file?

(Sorry I can't upload the BIN file to here, will failed if I upload BIN file, how to send the file to you?

If it can work in your side, then maybe my HW has problem.

The chiset is TPS65987DDHRSHR.

Hi Jack,

Please send me a pm with your binary file if you are unable to upload it here. 

Thanks,

Emma

Hi Emma,

Attached please find my binary file, could you please help to try in your side?

ti read3.zip

Hi Jack, 

I will try this and update you tomorrow with the results. 

Thanks,

Emma

Hi Jack,

I tried your binary file that you sent me. I received the message "SPI Flash to device successful". Then I cycled power on the EVM and went into debug mode and saw that the mode register 0x3 (in the debug register tab) was in APP mode. 

Please note that cycling power is mandatory after programming the device. 

To check that you have the correct I2C address in the GUI please do the following:

- Go to the Adapter tab in the GUI

- Configure I2C/SPI Adapter Settings 

- Sweep I2C address range for device response

- Start

You should see the following, which tells you that I2C1 has the correct address:

Once you have confirmed your adapter, please flash your device by the following method: Binary > Flash from current project. Power down the device. Then go to the debug mode, and check the mode register. Let me know your results.

Thanks,

Emma

Hi Emma,

Thank you very much for your support.

I try in my side again, still in BOOT mode.

But if I short SPI_MISO to GND, same as press S3 on the EVM, TPS65987D can enter APP mode.

I use Winbond W25Q80DVSNIG, which near W25Q80JVNIQ.

Any idea?

thanks,

Jack

Hi Jack,

Can you flash your project to your device in APP mode using the method described above and then restart the EVM? I was able to verify your project is compatible with an EVM. You should not need to restart the microcontroller or short SPI_MISO to ground for this solution to work. 

Thanks,

Emma

Hi Emma,

Yes, I can flash my device.

I check the SPI bus with oscilloscope, no signal on SPI_CSZ, SPI_CLK, SPI_MISO when power on.

It seems TPS65987D waiting one signal to continue.

May I know which signal I should check?

I shorted SPI_MISO to ground and TPS65987D can enter APP mode, it proves the TPS65987D is good, can work with internal FW.

But just didn't read exteral flash.

Thanks

Jack

Hi Jack, 

If you short SPI_MISO to ground, the flash will never communicate with the TPS65987D. You will need to restore the pull up on the flash. 

Thanks,

Emma
