Linux USB problems with TE0720-03-2IF on TE0701

[OK]

Hi,

I am using a TE0720-03-2IF module on a TE0701 carrier for quite some time now. For a new application I need to use the micro-USB port in Host-Controller mode. At the moment I am getting a -99 error code when using lsusb and no USB devices seem to be recognized from the kernel. However, when stopping boot at uboot I can see attached USB devices using "usb start" command and can verify that the USB port is operating in host mode.

Some details about the toolchain:

• Vivado/Petalinux 2019.1 (I would like to refrain from upgrading due to a lot of external IP cores...Never change the Vivado version for a working project)
• FSBL: I use the FSBL from https://github.com/Xilinx/embeddedsw at tag "release-2019.1" and used the FSBL hooks provided here https://wiki.trenz-electronic.de/display/PD/TE0720+Test+Board as a patch which is applied by petalinux-build. I can verify that the custom FSBL is used due to the prints on UART during startup. So the USB reset seems to work.
• The devicetree has the entries as listed for the testboard and USB should be in "host" mode within the kernel. dmesg shows that the EHCI driver is loaded.
• Analog devices linux kernel: https://github.com/analogdevicesinc/linux/tree/2019_R1 at version 2019_R1.

I am out of ideas as the most common cause for this problem seems to be the lack of the custom FSBL hooks but as I have these applied and during uboot USB works just fine, I suspect some issue within the analog devices kernel. The strange thing is just that there absolutely no errors within the logs and USB device drivers and EHCI driver loads fine.

Does somebody have any clue or direction to look into?

Hi,
can you test one time with our reference designs please:
https://wiki.trenz-electronic.de/display/PD/TE0720+Test+Board
binaries for different assembly variants are included.

[OK]

Yes, I have tested that and It works fine. As I would expect...

How to proceed? My deviations from test board are as following:

• U-Boot --> Should be the same, the platform-top.h change is applied by petalinux
• FSBL --> Should be the same, I have integrated the TE hooks as a patch
• Bitstream --> Different but is based on the Test Board Design
• Linux Kernel --> Completely different as it is the Xilinx linux kernel modified by Analog Devices and modified by me with additional custom drivers for IP Cores

I still suspect the kernel/kernel config to be an issue, I just don't know where to start/look for details.

Hi,
check device tree. Unfortunately we document only changes which we must do manually (default device tree and changes from xilinx during xsa import are not included into our documentation):
https://wiki.trenz-electronic.de/display/PD/TE0720+Test+Board#TE0720TestBoard-DeviceTree
For kernel we did not change anything which is related to USB...it's Xilinx default

Xilinx has some documentation here:
https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18842272/Zynq+Linux+USB+Device+Driver
or you check Xilinx device tree git:
https://wiki.trenz-electronic.de/display/PD/PetaLinux+KICKstart#PetaLinuxKICKstart-References

PS: Xilinx Linux kernel is changed very often...see Xilinx petalinux release notes from different petalinux versions, we have some links here:
https://wiki.trenz-electronic.de/display/PD/Xilinx+Development+Tools#XilinxDevelopmentTools-XilinxSoftware-ProductUpdateReleaseNotesandKnownIssues

[OK]

Thanks.

I have your devicetree entries. I'm wondering if the usb reset pin has to be configured. If I see it correctly the USB reset is done via the FSBL which is in turn piped through the CPLD (from the schematics...). Does the linux kernel also has to toggle the reset pin (and if yes which GPIO/MIO Pin does that correspond to?)? I think the problem ist that the EHCI device is never discovered/probed by the kernel. I see a bunch of USB drivers (and also usbfs) loaded in dmesg but it seems the EHCI is never discovered. In the u-boot console everything works fine and the EHCI is working just fine (attached devices are also correctly indentified).

[JH]

Hi,
did you checked, if these settings are enabled on your kernel:
https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18842272/Zynq+Linux+USB+Device+Driver#ZynqLinuxUSBDeviceDriver-HostMode

can you share your whole boot log?

br
John

[OK]

Yes, these settings are enabled.

Here is the boot log captured via UART:

Hi,
I haven't 720 on place at the moment. Can you boot one time with our design and check which drivers are load (and/or share log also here).

you should compare this one. and connect/remove/connect one time usb stick after booting was finished (best case in both design)

Hi,

I've just recorded it. I will check it for differences regarding USB. The problem is directly that the chipidea-usb EHCI controller is never probed/showing up for my image. I have no idea why...

This is the log using the Trenz demo board image:

Hi,
what's your final device tree?

Our wiki show only extensions, not final one with xilinx default setup included....

[OK]

The other part is within the auto-generated part by xilinx. The single parts say:

In the zynq-7000.dtsi:

Code Select Expand


usb0: usb@e0002000 {
compatible = "xlnx,zynq-usb-2.20a", "chipidea,usb2";
status = "disabled";

interrupt-parent = <&intc>;
interrupts = <0 21 4>;
reg = <0xe0002000 0x1000>;
phy_type = "ulpi";
};


Note the status="disabled" which is overriden by the pcw.dtsi.
In the pcw.dtsi:

Code Select Expand


&usb0 {
phy_type = "ulpi";
status = "okay";
};


The system-top.dts defines the order of inclusion:

Hi,
xilinx use other kernel version as you, maybe this is the different...

what you can also try is replace kernel and device tree separately with this one which is generated by petalinux, so narrow down the problem...

sorry I can't help much more at the moment.

br
John

[OK]

No problem, this was already helpful to get closer to the source of the problem.

Unfortunately I cannot switch to the Xilinx kernel as I am relying on the Analog Devices linux kernel which as a modified industrial I/O system and a lot of special drivers within the kernel. This special kernel is actually just a fork of the Xilinx kernel with additions/changes. I will try to find the differences within the USB subsystem. It does not look too different from the Xilinx kernel though.

I have looked at the source code of the chip idea driver (actually quite a short driver code) and there is no debug message if the device cannot find the phy handle. I will modify the driver and add some debug messages/printks ... maybe this will give me some debug output during boot.

[OK]

Hi,

I found the solution but it was a deep dive into the kernel, the usb subsystem and other stuff. In the end the reason for this behaviour ist quite simple.

For weird reasons someone reverted an important commit in the Analog Devices Linux Kernel which originally added the support for the ULPI phy: https://github.com/analogdevicesinc/linux/commit/1f75f645a4e929e9432631ffbb13e8419ed98110
This commit only affects earlier release, namely before and including 2019_R1. It is already fixed for the 2019_R2 release of the kernel. The Trenz demo design is using a newer kernel version closer to 2019_R2. By adding the removed functions from the commit above back into the ULPI driver fixed all of my problems and USB is working fine now.

[JH]

I am glad you found solution and thanks for sharing the information.
