TE0820: dr_mode not found

[martin]

When loading the u-boot a few error message occurs.

First one is "ERROR: usb dr_mode not found"

The system-top.dts is

Code Select Expand

/dts-v1/;
/include/ "zynqmp.dtsi"
/include/ "zynqmp-clk-ccf.dtsi"
/include/ "pl.dtsi"
/include/ "pcw.dtsi"

chosen {
bootargs = "earlycon clk_ignore_unused";
stdout-path = "serial0:115200n8";

aliases {
ethernet0 = &gem3;
serial0 = &uart0;
spi0 = &qspi;
};
memory {
device_type = "memory";
reg = <0x0 0x0 0x0 0x40000000>;
};
};


The usb0 part of the pcw.dtsi is

&usb0 {
status = "okay";
xlnx,usb-reset = <0x2faf080>;
};

The hole U-Boot messages are...

In Vivado 2017.3 -> Zynq Ultrascale+ IP -> Clock Configuration -> GT Lane Reference frequency -> USB0 is "Ref Clk3" with 100MHz
In Vivado 2017.3 -> Zynq Ultrascale+ IP -> I/O Configuration -> High Speed -> USB -> USB 0 -> USB 3.0 is enabled to "GT Lane0"

Hope somebody have me a hint what I can try next.

Thanks,

Hi,
do you test with prebuilt files from reference design? Does it work?

Hi John,

with the BOOT.bin from the prebuild files "te0820-test_board-vivado_2017.1-build_04_20170821162153-1.zip\test_board\prebuilt\boot_images\te0820_2eg_1e\u-boot\" I get following output.

U-BOOT for petalinux


I2C gets an error, but it seems that USB is working or ignored...

But know I see  you also using the ZynqMP ZCU102 rev B deconfig files to build u-boot

[JH]

Hi,

uboot i2c error can be ignored.

I2C is available on linux.

"ZynqMP ZCU102 rev B" is from petalinux generation. Xilinx petalinux used this as default template. Settings will be overwrite by HDF import, Device Tree and platform-top.h.

There is a petalinux template project on <reference design>/os/petalinux
Usage:

PS: I will upload 2017.2 design with wiki description tomorrow.

Hi,
short info: TE0820 2017.2 Reference Design is online:

Hi John,
thank you for the hint.
Is it enough to replace the board files or how can I update a existing project with the new settings?
Thanks,
Martin

[JH]

Hi,

depends on changes you has done on the design and what you need to update.
Did you change PS setting? Did you use Vivado Project with TE-Scripts or only Boart part files?

br
John

[martin]

Hi John,

no, I hadn't changed the PS settings.
And yes, I used the test_board 2017.1 with the TE scripts to generate the initial project.

Thanks,
Martin

[JH]

Hi,
best way is, add your changes from old project to new one.

But you can also try following:

• Make a backup copy of your project
• Open your Project with Vivado 2017.2 and use Vivado IP Upgrade Function.
• Save and close Vivado Project
• Replace "board_files" folder with new one from 2017.2 reference design
• Replace "console" folder with new one from 2017.2  reference design
• Replace "scripts" folder with new one from 2017.2  reference design
• Remove all bash files from main directory(_create_win_setup.cmd, and generated one like design_basic_settings.cmd....)
• Copy "_create_win_setup.cmd" from 2017.2 reference design into this folder
• Create Bash files with "_create_win_setup.cmd"
• Set correct board part on "design_basic_settings.cmd"
• run Bash files vivado_open_existing_project_guimode.cmd
• On Vivado Block Design:
• Remove PS IP
• Add new PS IP
• Run Board Automation and connect IPs, if not done
• Check one time, if PS is configured

Hi,
some note:

"dr_mode not found" for Vivado 2017.3 or newer.

Add:

Code Select Expand

&dwc3_0 {
  status = "okay";
  dr_mode = "host";
};
to device tree.

2017.4 reference design for TE0820 is in process (will be come after TE0808,TE0807 and TE0803 update). Also special FSBL to program QSPI Flash, if boot mode is not JTAG.
