There aren’t enough details in your post for us to help you. While we are happy to assist you with any concerns you may have with peripherals in our device, we regret we are unable to assist you with external peripherals like LCD modules.

Drishti,

Which board are you trying to run the example on? Is it a custom board or the Launchpad (Launchxl-f28379d) or the Control card (TMDSCNCD28379D)?

What is the end application of the board ?

Which pins are the USB DM and USB DP connected on the MCU side?

Siddharth,

We want to use usb as pen drive for battery charger and the pins are GPIO 42 and 43 respectively.

Drishti,

Can you do a trace of the USB pins using a USB analyser?

That would help to narrow down the cause.
