TPS25750: TPS25750 I2Cs_IRQ

Pablo,

Have you configured the IRQ in the advanced tab of the GUI?

It will be disabled by default until you enable the Events.

Chuck

Hello,

Pablo

Pable,

Have you changed the Mask settings in the Advanced Tab?

You will also have to clear the IRQ register after boot and connection because default enabled Interrupts will occur on type C connection.

Regards,

Chuck

I haven't change the mask settings.

Yes. I have clearer the interrupts. I can see the effect of clearing by reading int_even1 register. Also pluging the USB cable changes bits in int_event1 as expected.

Pablo,

I commited to other tasks until early next week, but based on what you are describing, I will need to address this on our EVM.

Are you able to post either you configured binary or the JSON file that you are using for configuration for me to use with my testing.

Regards,

Chuck

Here's the .JSON. Also tried to have GPIO 1 and 2 pullup&&pulldown enabled so that GPIO1 would be pulled low and GPIO2 would be pulled high. GPIO2 seems to be high and GPIO1 low.

Pablo,

I will look into this tomorrow.

Pablo,

I lost this message in my stack of support items.  I apologize for the long delay.

Are you still having issues with our IRQ configuration?

I still have the problem.

ps. It would be nice to know how to decode the Multiplexing for GPIO Pins.

Pablo,

Which I2C_IRQ are you attempting to work with?

The GPIO events are defined in the TPS25750 Host Interface Technical Reference Manual.

You can also find them in the Advanced tab of the GUI.

Regards,

Chuck
