TPS55288EVM-045: I would like to know how to operate the EVM.

Hi Nomura,

See from the left-bottom reminder, the firmware of USB2ANY needs to be updated, please follow the below steps:

The steps to upgrade the firmware are as follows:

1. Close the TPS55288 GUI Software;
2. Connect USB2ANY to the USB-A port of the laptop, use something to hold the small black dot, and then release it after the update is completed;
3. Open USB2ANY Explorer (USB2ANY needs to be connected to open the Explorer software), and it will prompt to update the firmware.
4. Update the firmware.

BRs,

Bryce

Dear　Bryce,

I don't understand the explanation.

1. Close the TPS55288 GUI Software;⇒OK
2. Connect USB2ANY to the USB-A port of the laptop, use something to hold the small black dot, and then release it after the update is completed;⇒I plugged it into a USB port and pressed the little black dot. How long do you press? I don't know if the update is complete.
3. Open USB2ANY Explorer (USB2ANY needs to be connected to open the Explorer software), and it will prompt to update the firmware.⇒Is the USB2ANY EXPLORER pictured on the right?
4. Update the firmware.

Step2: you should keep pressing the black dot, and at the same time, open the USB2ANY explorer, then you will see the reminder of update the firmware. Click update, and when the update is finished, then release the black dot.

The software is right from your screenshot.

Dear　Bryce,

I held down the black dot and opened USB2ANY Explorer.

I pressed OK as it was.

Waited.

Which is the software?
Where's the update button?

Hi Nomura, 

The screenshot 1 and 2 are correct, but at screenshot 3, the press of the black hole may be lost, please check item1 and item2 at the screenshot.

Dear　Bryce,

I've tried many times, but I can't.

Hi Nomura,

When the screenshot3 shows, please try to disconnect the USB from the PC, and plug it again.

Dear　Bryce,

I was able to update.

When I connected the evaluation board and opened the GUI again, the following error appeared.

Hi Nomura,

Have you powered the input supply on? The Vin&EN&VCC needs to be powered on when connecting with GUI.

BRs,

Bryce

Dear　Bryce,

I was able to connect. Changing the output by GUI also works well.
Proceed with the assessment.
Thanks for the support.
