USB 2.0 host mode in AM572x EVM

takashi machida

I hava a query about AM572x EVM.

According to the AM572x General Purpose EVM HW User Guide( http://processors.wiki.ti.com/index.php/AM572x_General_Purpose_EVM_HW_User_Guide ),

"The AM572x USB2 port has its USB_ID pin (GPIO7_24) pulled high for client, or device, mode. By default, the USB2 port is routed to a microUSB client port (P7) on the Processor Module. Alternatively, the AM572x USB2 signals are also available on the expansion connectors for use with an expansion board. To route the USB2 port to a custom daughter board on the expansion connector, remove R210 & R211 and populate R314 & R315 with 0-ohm resistors. To support host mode or OTG, VBUS 5V must be supplied by the custom daughter board."

I would like to run the USB2.0 for host mode.

Expansion Board as above, where can I get it ?

Or I must create the it ?

Thanks

Hi,

Please see page 14 of the AM57X EVM Processor Module Schematics. The signals USB2_DPEX, USB2_DMEX and USB2_ID are routed to expansion connectors P16 and P17. However these signal are not used on the expansion board, which comes as part of the AM57X GP EVM. The GP EVM schematics can be found in the "Design Files" section here: www.ti.com/.../tmdxevm5728 Documents

These signals were included on the EVM for internal testing purposes. There are currently no plans for TI to create+provide an expansion board that enables USB Port 2 Host functionality on the AM572x EVM.

Thank you for prompt response.

Apparently, I have to create the expansion board for USB2.0 host mode.

Thanks
