Part Number: PROCESSOR-SDK-AM335X
Other Parts Discussed in Thread: AM3357

Tool/software: TI-RTOS

I used the example code of USB_DevMSC_evmAM335x_armExampleProject. And i set the usd number to USB_1.

However, when I plugged in the computer, it didn't respond.

Through debugging, I found that I only have a Suspend interrupt.Other interruptions have not been generated.

I usd a AM3357 development board. It`s based on icev2AM3359.

Hi,

The USB_DevMsc_evmAM335x_armExampleProject is for AM335x GP EVM, USB instance 0 is the USB device port we used for test with a PC. The GP EVM has also a USB host port, it is USB instance 1, we used USB_HostMsc_evmAM335x_armExampleProject for testing with a USB memory thumb drive. We didn't see any issue.

You mentioned "I usd a AM3357 development board. It`s based on icev2AM3359." AM335X icev2 card doesn't have any USB port. Is this a board you developed your own? Do you have any hardware test proving the USB is working?

Hi,

Please clarify what exact board you used for test?

"It`s ok by change a board."=========> do you mean you are able to change to a TI AM335x GP EVM? Or you found the USB 1 was working now using your own board?

What is the new issue?
