Dear Sir ,

I have designed two sets of Type A USB2.0 . The SoC_USB1 (J15 port) works , however SoC_USB0 ( J16 port) failed that I noted this port was used for Type C in EVM board. Do I need to change any setting ?

Please review my schematics as the attached file .

Hi Jack,

Can you please attach the Linux boot log?

What is the output of 'lsusb' command on the Linux console?

Did you set "dr_mode = 'host';" for usb0 node in your board device tree?

Dear Bin ,

1 . Can you please attach the Linux boot log?

how to see the log ?

2. What is the output of 'lsusb' command on the Linux console?

How to check ?

Did you set "dr_mode = 'host';" for usb0 node in your board device tree?

We didnt make any change that I directly use the tisk-default-image (am62xx-evm-08,03,00,19 version) , is it been set already ?

This is likely the problem. The defaule SDK image for the EVM set dr_mode to "org", because the EVM usb0 port works in dual-role mode through the type-C connector. However, your board designs usb0 to be in host-only mode, so you need to set USB0 dr_mode to "host" in your board device tree.
