AM5728: USB XHCI problem in U-boot

Part Number: AM5728
Other Parts Discussed in Thread: PMP, , BEAGLEBOARD-X15

We are working towards our own board based on the AM572x EVM. I am having problems with XHCI USB devices in u-boot. All tested devices work fine in linux but if "usb start" is run during u-boot, the XHCI controller fails and u-boot aborts and reboots. EHCI and other devices all work fine, but something as simple as an XHCI hub or XHCI thumb drive causes this issue. The issue is identical on all 3 USB ports on the EVM and occurs regardless of whether or not other USB devices are plugged into other ports on the EVM.

I saw this link https://e2e.ti.com/support/interface/f/138/t/592829 which may or may not be related, but it stated that a different version of u-boot resolved the problem. I am wondering if this could be the case with the AM572x and if so where I might find the allegedly magic code.

The condensed part of the error message in u-boot is

Device not responding to set address.

    Hi,

    It sounds like the issue happens on the AM5728 GP EVM, not your custom board, correct?

    The issue happens even if no any USB device is attached to any of the 3 USB ports behind the hub. is it correct?

    Which Processor SDK version do you use?

    Yes, this problem happens on the AM5728 GP EVM.

    I am using platform SDK 5.02.00.10, which uses u-boot u-boot-2018.01+gitAUTOINC+313dcd69c2-g313dcd69c2.  

    The issue happens if no other USB device is attached to any of the ports. All I need to do is insert an XHCI usb drive, such as the Samsung 32GB BAR metal, into any one of the ports on the EVM and start the board. u-boot will fail and reset as I described below as soon as the command "usb start" is issued.

    This message doesn't look right, it misses board information. What version of the EVM do you have? Any label do you see on the board?

    Hello

    Sorry, I snipped that out by mistake.

    CPU : DRA752-GP ES2.0
    Model: TI AM5728 BeagleBoard-X15
    Board: AM572x EVM REV A.3A
    DRAM: 2 GiB
    MMC: OMAP SD/MMC: 0, OMAP SD/MMC: 1

    I switched back to using the prebuilt MLO and u-boot.img which came with the PLSDK and USB is working properly in u-boot. To help troubleshoot, I have found that if I do

    git checkout 313dcd69c2

    and rebuild u-boot USB is back to working.

    git reports that this is now a detached head so this commit 313dcd69c2 does not seem to correspond to any known branch. I have done a diff of this vs. the master branch (commit d73d81fd85e4a030ade42c4b2d13466d45090aa3)  and found that every single file has changed because somebody modified the copyright notices in every file, and therefore it is nearly impossible to determine what the difference might be.

    I have made almost no changes to the u-boot source code so it is easy for me to create a new branch from this working 313dcd69c2 commit and port over my changes.

    This seems likely to be a git problem, possibly due to my error when I set up my own git repo for making my own local u-boot modifications.

    Thanks for the help, but for the time being this appears to be resolved.

    Hi,

    I am glad the issue is solved. Thanks for the update.
