Part Number: TPS65988

Dear Sirs,

I have use PlugEvent_Port in other GPIO(1,14,15,18) is okay. But GPIO15 is invalid.

I also test GPIO15 without Event. High/low is okay.

Please help give me suggestion. Thank you.

Hi Eric,

GPIO14 and GPIO15 are use for PWM. When tried to use as other function will cause the EVM not to recognize a device plugged in causing the GPIO to toggle High/Low. For more information access the link bellow for the host interface reference manual. http://www.ti.com/product/TPS65988/technicaldocuments. Lets us know if this solves your thread.

Regards,

Francisco

Not TI EVM, I use in custom target board.

I have tried PortA PlugEvent in GPIO(14,18) is okay.

I have tried PortB PlugEvent in GPIO(1) is okay.

I have tried GPIO mode in GPIO(15) is okay. but PortA PlugEvent in GPIO(15) is fault.
Please help give me suggestion.

Regards,

Eric

Hi Eric,

You can not have two GPIOs serving the same configuration, since this is not supported you may be getting a fault. If setting two GPIOs for the same even only the lower GPIO would be valid. Let us know if this solves your thread.
