TPS6594EVM: Regarding setup for TPS6594EVM

Hello Kotaro,

If you click the circling arrows in step 1 of that pop-up are there any COMM ports listed in the drop down menu?

Can you confirm jumpers J47 and J37 are set to "Master"? I know this is a bit confusing since the '1111 is typically a slave device, but the jumpers are connecting I2C lines to the USB.

If trying to power EVM via USB, use the jumper connecting VSYS and V3V3.

Hello Michael san

COMM port is not displayed.
I have also set J37 and J47 as masters, but the devices are not recognized.
Are there any other possible problems?

Thanks

Can you try a different USB-to-USBC cable?

When you make the connection to the USB, which of the on board blue LEDs turn on?

Dear Michael san

I tried a different cable , but situation is not changed.

In the following , I tried a both conditions,

LED turn on : D3 , D5 , D6  or D4 , D5 , D6 

Thanks

In Device Manager do you see "ACCtrl" listed like below?

Instead of using the Quick Start Page, could you try using the register map page for the TPS6594x?

I can't see "ACCtrl" .

Yes , I am using the register map page for TPS6594x

Althogh I tried another PC , but situation is not changed..

Thanks

Kotaro,

Do you have another TPS6594x EVM you could try? I am beginning to wonder if there is something wrong micro controller on that particular EVM.

1111  has an I2C address of 0x4C to the default 0x48 

Hello Nimrod,

Mike should be able to look into this by Thursday. Thank you.

Alex

Kotaro,

Have you had the chance to try another EVM?
