TE0726-03-07S-1C and reference designs issues
« on: November 26, 2021, 01:19:29 PM »
Hi,
I'm trying to follow the TE0726 Test Board example https://wiki.trenz-electronic.de/display/PD/TE0726+Test+Board with TE0726-03-07S-1C board. When I create my PetaLinux project with exported .xsa-file, after the command
> petalinux-build
I receive an error:

---------------------
How to solve the problem?
Vivado, Vitis, Petalinux - 2020.2. I found the similar eror on xilinx site - https://support.xilinx.com/s/article/76575?language=en_US, but it is for Versal device.

Hi,
it looks like you use our template correct?
Did you run hw import of the XSA file before you run build?
Do you use a supported Linux version for petalinux built enviroment? Did you  install all neccesary packages? See: https://wiki.trenz-electronic.de/display/PD/PetaLinux+KICKstart#PetaLinuxKICKstart-PetaLinuxInstallation.1
Can you try out one time prebuilt xsa from a dual core variant (we generate linux files with a dual core variant, this should work also on the single core.) So you can check if single core xsa is the problem.

Yes

Yes

I use openSuse, but I installed all the same necessary packages

I tried for TE0726-03-41C74-R and the build was successful, no any errors. Then I again tried to build for TE0726-03-07S-1C and again the same error.

So the problem is in the single core. Can you please fix it?

In this case it's bug from on xilinx xsa import. I can't fix it. Check automatically generated part from device tree.
Sometimes Xilinx published patches, sometimes you must generate your own one.
I found an single core problem for older versions:
https://support.xilinx.com/s/article/70402?language=ja

or

https://support.xilinx.com/s/question/0D52E00006hprmh/petalinux-20201-build-error-device-tree?language=en_US

both looks like the same problem.

I tried to use the patch from https://support.xilinx.com/s/article/70402?language=ja
I placed 0001-Update-the-logic-to-check-if-cpu-is-present-in-the-d.patch file in the <plnx-proj-root>/project-spec/meta-user/recipes-bsp/device-tree/files and changed <plnx-proj-root>/project-spec/meta-user/recipes-bsp/device-tree/device_tree.bbappend file:
device_tree.bbappend:
Code: [Select]
SRC_URI_append = "\
     file://0001-Update-the-logic-to-check-if-cpu-is-present-in-the-d.patch \
"

FILESEXTRAPATHS_prepend := "${THISDIR}/files:"

SRC_URI += "file://system-user.dtsi"


python () {
    if d.getVar("CONFIG_DISABLE"):
        d.setVarFlag("do_configure", "noexec", "1")
}

export PETALINUX
do_configure_append () {
<------>script="${PETALINUX}/etc/hsm/scripts/petalinux_hsm_bridge.tcl"
<------>data=${PETALINUX}/etc/hsm/data/
<------>eval xsct -sdx -nodisp ${script} -c ${WORKDIR}/config \
<------>-hdf ${DT_FILES_PATH}/hardware_description.${HDF_EXT} -repo ${S} \
<------>-data ${data} -sw ${DT_FILES_PATH} -o ${DT_FILES_PATH} -a "soc_mapping"
}
Still can't build.

I looked into 0001-Update-the-logic-to-check-if-cpu-is-present-in-the-d.patch. It modifies the file /device_tree/data/device_tree.tcl. Where is this file located? Can I modify it manually?

Hi,
this patch from xilinx was for older petalinux version.I think it's not longer compatible.

Can you add this one to your device tree for your single core variant and try again:

Quote
&amba {
   ptm@f889d000 {
      cpu = <&cpu0>;
   };
};

John,

[INFO] Successfully built project.
I successfully started Linux on the device and can use Linux shell.

Thank you!

Oh, I successfully got linux shell only with your boot.scr and image.ub. With my boot.scr and image.ub I just have:
Zynq>
Maybe it is because I did nothing when configured PetaLinux project. Do you have any documentation how to configure? Or any scripts that configure it the same way as you do?

Hi,
https://wiki.trenz-electronic.de/display/PD/Distro+Boot+with+Boot.scr

or use simple our boot.scr from the reference design
