[U-Boot] USB1 Fastboot

Other Parts Discussed in Thread: AM3354

Hi all,

in our custom board, we use the AM3354, we want to use USB1 as peripheral to use fastboot.

In the U-Boot (U-Boot 2013.01.01) I changed the USB Base Address to 0x47401800, after loading U-Boot SW and starting fastboot, Windows don't recognize any new Hardware.

My Question is, do I need to change anything else to use USB1 as peripheral and use fastboot? Maybe I need to change something in the fastboot sources?

Thanks for the help.

Best Regards,

Markus

    Hi Markus,


    Where exactly in code you are doing this change?

    Macros for USB0 and USB1 are already defined in am335x_evm.h file.  Can you try with the following patch.

    diff --git a/include/configs/am335x_evm.h b/include/configs/am335x_evm.h
    index a0f843d..88f28a0 100644

    Hi Pankaj,

    I made the same changes, with no success.

    If I start fastboot I get the following Output:

    U-Boot SPL 2013.01.01 (Jan 07 2014 - 11:01:32)
    CCxyzModem - CRC mode, 0(SOH)/151(STX)/0(CAN) packets, 3 retries

    fastboot serial number = 78c5e5be6b3078c5e5be6b31
    Fastboot entered...

    Everything looks fine, but on windows site nothing happens.

    Thanks for your Help.

    Best Regards,

    Hi,

    I tried today to run fastboot over USB1 on the AM335X Eval Board and got the same behavior.

    Do I need to disable the ID Pin Logic or something else to get it working?

    [Update]

    Here is the fastboot log:

    U-Boot# fastboot

    Hi,

    I got it working.

    To use Fastboot on USB1 on the Eval Board, I had to modify the USB1MODE register at usb-initialization.

    Set the IDDIG Field to B type and IDDIG_MUX Bit to 1.

    Best regards,

    Markus
