AM5728: GP evm/RTOS/USB3.0

Part Number: AM5728
Other Parts Discussed in Thread: TUSB8041

I am using AM5728 GP evm board.
I am using RTOS and the version is processor_sdk_rtos_am57xx_5_02_00_10.

I want to use USB3.0 on GP evm board.
I have checked the examples provided by the RTOS SDK.
And I found that the 'USB_HostMsc_idkAM572x_armExampleProject' example supports USB3.0 on the idk board.

Can I test USB3.0 by modifying the source code of the example on the GP evm board?
I saw that this is not possible with GP evm board. However, does the TUSB8041 chip on the GP evm board support USB3.0?

I wonder whether it is impossible because of the hardware design of the GP evm board, or because there is no content in the source code of the example.

If there is a way to test USB3.0 on GP evm board, I would appreciate it.
Finally, i plan to use USB3.0 in device mode.

I would appreciate your reply.

Thank you.

wonjune,

The EVM supports USB3.0, as documented in https://www.ti.com/lit/pdf/spruig1 in section 9.3.2:

AM572x USB1 (USB3.0 Host) - P13, P15 (Processor Module)

The AM572x USB1 port supports USB3.0 speeds and is connected to a 4-port USB3.0 hub. Three are accessible on the USB3.0 Host ports while the fourth is located in the eSATA/USB combination port and is therefore limited to USB2.0.

As you note, the Processor SDK RTOS package includes USB3.0 host mode support, validated on the IDK only. We do not have examples for device mode under RTOS for USB3.0, only USB2.0.

Examples on the EVM are based on the Processor SDK Linux as detailed in http://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Foundational_Components/Kernel/Kernel_Drivers/USB/DWC3.html

Best regards,
