USB3.0 Test on u-boot

Other Parts Discussed in Thread: 66AK2E05

Hi Community,

Im working on K2E EVM(66AK2E05). I want to test USB3.0 on uboot, i saw uboot env "usb", but i realize i cant test USB3.0 because of usage of this env: "usb test [dev] [port] [mode] - set USB 2.0 test mode".

I read some discussions about USB3.0 can be used with Linux. How can i test USB3.0 on uboot? Can i test USB3.0 on ARM with RTOS, not Linux? I cant Load Linux image to ARM core.

Best Regards,

Srt

    Hi Srt,

    I read some discussions about USB3.0 can be used with Linux. How can i test USB3.0 on uboot?


    You can insert the USB3.0 compatible pen drive on the EVM USB port and can test the read and write test on it using uboot. Please refer below thread.

    Also we recommend you to go through the uboot open source code for test usage. It is not TI specific command/test case.

    Can i test USB3.0 on ARM with RTOS, not Linux?


    If you are using TI-RTOS, please check on TI-RTOS forum for faster response.

    Thank you.

    Hi Raja,

    Thank you for your response. I want to test USB3.0 on u-boot if i can, otherwise i think to test USB3.0 on RTOS.

    I have a USB3.0 Flash Stick. I want to test this on uboot prompt. I try to write 256Mb Data to USB Flash Stick with command: "usb write 0x80000000 0x800 0x80000". All process takes 175sec, its equal to 1.46Mbps. Its very slow.

    How can i test USB3.0 correctly?

    Best Regards,

    Srt

    We are not sure about the limitation of USB on u-boot. I recommend you to understand the UBOOT open source and modify for your purpose.

    Thank you.
