PetaLinux 15.4 and MicroZed BSP

Former Member

Hi,

I'm trying to build with petalinux 15.4 and your bsp file (from http://microzed.org/support/design/1519/10).
I'm getting the build error:
[ERROR] ERROR (phandle_references): Reference to non-existent node or label "usb_phy0"

It only happens if I run "petalinux-config".
This sequence works:
$ petalinux-create -t project -s mz_7010_2015_4.bsp
$ cd mz_7010_2015_4/
$ make

This sequence doesn't work:
$ petalinux-create -t project -s mz_7010_2015_4.bsp
$ cd mz_7010_2015_4/
$ petalinux-config
$ make

Note that I do not change any configuration, I only open the petalinux-config tool and close it again.

As side note: doing a config of rootfs works
$ petalinux-config -c rootfs

I run petalinux on a virtualbox with ubuntu 14.04.

Best regards
/Fredrik

    Hi fredrik,

    Looking at your console output, it looks like PetaLinux is re-running device tree generation which is likely overwriting system-conf.dtsi or system-top.dts or BOTH.

    In 2015.4, we needed to add the following entries to the device tree in the respective files in order to get USB host mode working:


    In the system-top.dts file:

    &usb0 {t
    tstatus = "okay";
    tdr_mode = "host";
    tusb-phy = <&usb_phy0>;
    } ;

    In the system-conf.dtsi file:

    usb_phy0:phy0 {
    ttcompatible="ulpi-phy";
    tt#phy-cells = <0>;
    ttreg = <0xe0002000 0x1000>;
    ttview-port = <0x0170>;
    ttdrv-vbus;
    t};

    Can you take a look at either of those files and see if one or both of the entries above is missing after running petalinux-config?

    If you do not need to use USB mode, you can simply remove these entries from your device tree files in the folder subsystems/linux/configs/device-tree/ folder within your PetaLinux project folder.

    Regards,

    -Kevin

    Thank for your quick response.

    It is system-conf.dtsi that gets changed by petalinux-config.

    The changed part is:
    Before config:
    / {
        model = "picozed_2015_4";
        aliases {
            serial0 = &uart1;
            ethernet0 = &gem0;
            spi0 = &qspi;
        };
        chosen {
            bootargs = "console=ttyPS0,115200 earlyprintk";
        };
        memory {
            device_type = "memory";
            reg = <0x0 0x40000000>;
        };
            
        usb_phy0:phy0 {
            compatible="ulpi-phy";
            #phy-cells = <0>;
            reg = <0xe0002000 0x1000>;
            view-port = <0x0170>;
            drv-vbus;
        };
    };

    After config:
    / {
        model = "mz_7010_2015_4";
        aliases {
            serial0 = &uart1;
            ethernet0 = &gem0;
            spi0 = &qspi;
        };
        chosen {
            bootargs = "console=ttyPS0,115200 earlyprintk";
        };
        memory {
            device_type = "memory";
            reg = <0x0 0x40000000>;
        };
    };

    Do you have any suggestion how to fix this? I do need the USB functionality.

    Best regards
    /Fredrik

    Hi Fredrik,

    That question is actually for you to decide.  If you don't need USB for your end application, it is fine to leave it out for now.

    If you do decide to leave it out, then remove the following lines from the system-top.dts file:

    &usb0 {
    status = "okay";
    dr_mode = "host";
    usb-phy = ;
    } ;

    That way you can eliminate the USB worries altogether.  If you decide later that you need USB, then add those sections described in my first post to the respective device tree sections before rebuilding.

    Regards,

    -Kevin

    (I don't know what happened to my previous comment/reply, so I'll try again.)

    Thanks for your replies.

    I diffed the device-tree files and it's system-conf.dtsi that changes during petalinux-config.
    It goes from:
    / {
        model = "picozed_2015_4";
        aliases {
            serial0 = &uart1;
            ethernet0 = &gem0;
            spi0 = &qspi;
        };
        chosen {
            bootargs = "console=ttyPS0,115200 earlyprintk";
        };
        memory {
            device_type = "memory";
            reg = <0x0 0x40000000>;
        };
            
        usb_phy0:phy0 {
            compatible="ulpi-phy";
            #phy-cells = <0>;
            reg = <0xe0002000 0x1000>;
            view-port = <0x0170>;
            drv-vbus;
        };
    };

    To:
    / {
        model = "mz_7010_2015_4";
        aliases {
            serial0 = &uart1;
            ethernet0 = &gem0;
            spi0 = &qspi;
        };
        chosen {
            bootargs = "console=ttyPS0,115200 earlyprintk";
        };
        memory {
            device_type = "memory";
            reg = <0x0 0x40000000>;
        };
    };

    I do need the USB functionality. So I tried re-adding the original part with usb_phy0:phy0{..} and now petalinux-build runs ok again.

    (While this is an acceptable work-around, I would've been nicer if I could rerun petalinux-config without manually patching afterwards.)

    Thanks and best regards
    Fredrik

    Hi,

     

    I'm having a similar issue, but adding the usb_phy0: phy0 block to my system-conf.dtsi is causing a syntax error.

    Any help would be greatly appreciated.
