According to https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/1641152513/Kria+K26+SOM#Boot-FW-via-xmutil initial KV260 boards were shipped with a firmware that requires an update for xmutil tools to work appropriately. The corresponding firmware can be fetched from https://www.xilinx.com/member/forms/download/xef.html?filename=XilinxSom_QspiImage_v1.1_20210422.bin.
In Vitis 2020.2 there's a bug which limits the emulation capabilities with KV260. The current images are able to boot only up until the ramfs and end up in something like:
...

dtc -I dtb -O dts -o system.dts system.dtbEdit system.dts and add the following:

petalinux-build -c <package> # e.g. petalinux-build -c dfx-mgrthe resulting package will be built and archived, resulting in an .rpm file which you can often find at build/tmp/deploy/rpm/aarch64/dfx-mgr*.rpm.

echo $(($(fdisk -l /home/xilinx/ros2_ws/acceleration/firmware/xilinx/sd_card.img | grep 'img2' | awk '{print $2}') * $(fdisk -l /home/xilinx/ros2_ws/acceleration/firmware/xilinx/sd_card.img | grep 'Units' | awk '{print $8}')))
1024458752!!! note The offsets need to be calculated first.
Raw image files contain several partitions. The first one is often the boot partition and the second one typically contains the file system. The following two commands will help mount the first two:
# mount boot partition
mkdir -p /tmp/sdcard_img_p1 && sudo mount -o loop,offset=1048576 /home/xilinx/ros2_ws/acceleration/firmware/xilinx/sd_card.img /tmp/sdcard_img_p1

sudo umount /tmp/sdcard_img_p1 # or *_p2, as appropriateSee [^32] for more details:

sudo ./mkinitramfs.sh /tmp/sdcard_img_p2 test.cpio.gzIt's been observed that sd_card.img files get sometimes corrupted but neither ddrescue nor testdisk helped recovering them. The typicaly behavior observed in a corrupted image can be reproduced by trying to mount its second partition:
mkdir -p /tmp/sdcard_img_p2 && sudo mount -o loop,offset=1024458752 /home/xilinx/ros2_ws/acceleration/firmware/xilinx/sd_card.img /tmp/sdcard_img_p2
[sudo] password for xilinx:
NTFS signature is missing.
Failed to mount '/dev/loop1': Invalid argument
The device '/dev/loop1' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around???? warning "Reproduce this behavior with KRS hypervisor functionality"
```bash
cd ~/ros2_ws/xilinx/firmware
tar -xzf sd_card.img.tar.gz # decompress the image
cd ~/ros2_ws/
colcon acceleration hypervisor --dom0 vanilla --domU vanilla --ramdisk initrd.cpio # this works just fine, can mount afterwards
colcon acceleration hypervisor --dom0 vanilla --domU vanilla --ramdisk initrd.cpio.gz # this works just fine, can mount afterwards
colcon acceleration hypervisor --dom0 vanilla --domU vanilla --ramdisk rootfs.cpio.gz # this works just fine, can mount afterwards
colcon acceleration hypervisor --dom0 vanilla --domU vanilla --ramdisk test.cpio.gz
```
The current solution for this issue is to discard the sd_card.img file and create a new one from the sd_card.img.tar.gz file.
!!! note This might be related to the fact that p1 in the sd_card is filling and overloading p2.

To set up Xen hypervisor in PetaLinux, follow the Confluence instructions.
To set up XRT in PetaLinux, follow these instructions.
There're different ways to do. See PetaLinux Command Line Reference UG1157 for more details:
petalinux-buid -c <component> -x <verb>wherein <component> corresponds with one of the recipes, e.g. u-boot.
| verb | Description |
|---|---|
clean |
Cleans build data for the target component. |
cleansstate |
This removes the sstate cache of the corresponding component. |
distclean |
This removes the sstate cache of the corresponding component. |
cleanall |
This removes the downloads, sstate cache and cleans the work directory of a component. |
mrproper |
Cleans the build area. This removes the <plnx-proj-root>/build/ and <plnx-proj-root>/images/directories |
The following command builds SDK and copies it at <proj_root>/images/linux/sdk.sh:
petalinux-build --sdkThe following is the equivalent bitbake command bitbake
petalinux-user-image -c do_populate_sdkPress Ctrl-aaa twice.
xl console domU0 # or whatever the domain name isThe default FS built with PetaLinux may contain a wrong configuration. Make sure that the following is set appropriately in /etc/inittab
#PS0:12345:respawn:/bin/start_getty 115200 ttyPS0 vt102
X0:12345:respawn:/sbin/getty 115200 hvc0
By default, VMs created with the Imagebuilder tool (e.g. uboot-script-gen) through configuration scripts are dom0less at the time of writing. For example, in the following piece, Dom1 is Dom0less:
MEMORY_START="0x0"
MEMORY_END="0x80000000"
DEVICE_TREE="system.dtb"
XEN="xen"
DOM0_KERNEL="Image"
DOM0_RAMDISK="initrd.cpio"
NUM_DOMUS=1
DOMU_KERNEL[0]="Image"
DOMU_RAMDISK[0]="initrd.cpio"
UBOOT_SOURCE="boot.source"
UBOOT_SCRIPT="boot.scr"Through the xl tooling. For example:
# create config file and launch VM
cd /etc/xen
cat << EOF > example-minimalistic.cfg
name = "guest0"
kernel = "/media/sd-mmcblk0p1/Image"
ramdisk = "/media/sd-mmcblk0p1/initrd.cpio"
memory = 256
EOF
xl create -c example-minimalistic.cfg
You can exit Xen pressing Ctrl-] and then check that the VM is running:
root@xilinx-zcu102-2020_2-ros2-foxy:/etc/xen# xl list
Name ID Mem VCPUs State Time(s)
Domain-0 0 1024 1 r----- 206.3
guest0 2 255 1 r----- 9.0When VMs are dom0less, they will get presented as follows:
root@xilinx-zcu102-2020_2-ros2-foxy:/# xl list
Name ID Mem VCPUs State Time(s)
(null) 0 1024 1 r----- 722.6
(null) 1 512 1 r----- 722.6One way to attempt to access these VMs is by switching between serials/consoles as described above.
Press Ctrl-]. That'll exit from the DomU console.
It's been observe that PetaLinux creates file systems that miss some Xen-related folders. This leads to issues initiating DomUs:

mkdir /var/lib/xen
rebootWhen facing the following error:

Chances are that your Xen tree doesn't include https://github.com/Xilinx/xen/commit/ab9054b8e902b0fa80af02ad1e0a8c4d383e90e1 which fixes a bug with PV drivers that causes that error. Make sure you rebuild Xen including that commit.
colcon acceleration extensions enable emulations which forward ports between the guest/host machines. Particularly, the following flags are passed to QEMU: hostfwd=tcp:127.0.0.1:2222-10.0.2.15:22 (among others). To ssh into the emulation:
ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -p 2222 root@localhostHow do I scp files from/into an emulation launched through KRS tools (e.g. colcon acceleration emulation)?
colcon acceleration extensions enable emulations which forward ports between the guest/host machines. Particularly, the following flags are passed to QEMU: hostfwd=tcp:127.0.0.1:2222-10.0.2.15:22 (among others). E.g., to copy files from the emulation into the host machine:
scp -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -P 2222 root@localhost:/ros2_ws/lib/accelerated_vadd_publisher_once/*.csv .Just add --cmake-args -DNOKERNELS=true to the build command. E.g.:
colcon build --merge-install --mixin zcu102 --install-base install-zcu102 --build-base build-zcu102 --cmake-args -DNOKERNELS=true!!! note
This flag persists so if you wish to change it afterwards and re-build kernels, you'll need to set it to false --cmake-args -DNOKERNELS=false.
- Build firmware artifacts in
acceleration_firmware_*
- If your board is based on a Xilinx adaptive SoC (e.g. Versal, Zynq Ultrascale+, Zynq 7000), we recommend you to clone acceleration_firmware_xilinx and create a new branch for your board replacing all artifacts as defined in the ARTIFACTS.md file. Afterwards, submit a pull request.
- A minimal rootfs should be created including:
- ROS 2 Foxy (at least bare bones)
- Xen hypervisor capabilities
- Xilinx Runtime (XRT)
vanillaandPREEMPT_RTpatched kernels including:- LTTng kernel support
- U-boot with PXE support
- Create a sysroot (or an SDK that produces such sysroot) for the target rootfs. NOTE that this sysroot might differ across different file systems (e.g. Ubuntu-based vs Yocto-based).
- Add custom mixins in
acceleration_firmware_*for the new board. Seexilinx.mixin.templatefor an example.
The current implementation of KRS leverages Vitis Unified platform and compiler which expects to build one accelerator at a time. If two are being built simultaneously, undefined behaviour is triggered and typically, only one of the accelerators will finalize while the other one won't (and thereby no xclbin file will be generated as a result).
The solution to this is to serialize the generation of acceleration kernels using colcon arguments as follows:
colcon build --executor sequential --merge-install --mixin kv260 --install-base install-kv260 --build-base build-kv260For more, review this ticket.
KRS relies on imagebuilder which employs /dev/mapper. This Linux interface is a bit sensitive and if not disabled properly in past runs will lead into:
colcon acceleration linux --install-dir install-kv260

Tracing and benchmarking capabilities in KRS are available from *beta* release, and on.
*Check the `official releases <https://github.com/Xilinx/KRS/releases>`_ for more*.
Tracing is enabled by default in KRS provided LTTng (>=2.11.1) is found installed in the file system and the TRACETOOLS_DISABLED option is not set.
To disable, either uninstall LTTng or pass the -DTRACETOOLS_DISABLED=ON CMake argument while building the ROS 2 workspace as follows:
# while building packages for the workstation
colcon build --merge-install --cmake-args " -DTRACETOOLS_DISABLED=ON"

The Xilinx® boot image layout has multiple files, file types, and supporting headers to parse those files by boot loaders. Bootgen defines multiple attributes for generating the boot images and interprets and generates the boot images, based on what is passed in the files. Because there are multiple commands and attributes available, Bootgen defines a boot image format (BIF) to contain those inputs. A BIF comprises of the following:
- Configuration attributes to create secure/non-secure boot images - Bootloader - First stage boot loader (FSBL) for Zynq® devices and Zynq® UltraScale+™ MPSoCs - Platform loader and manager (PLM) for Versal™ ACAP - One or more Partition Images
To learn more, refer to:
Let's assume:
xilinx@xilinx:/tmp/latebinding$ ls
arm-trusted-firmware.elf fsbl-zcu102-zynqmp.elf tsn.bit
bootgen.bif pmu-firmware-zcu102-zynqmp.elf u-boot-zcu102-zynqmp.elfwhere bootgen.bif contains:
cat bootgen.bif
the_ROM_image:
{
[bootloader, destination_cpu=a53-0] fsbl-zcu102-zynqmp.elf
[destination_device=pl] tsn.bit
[destination_cpu=pmu] pmu-firmware-zcu102-zynqmp.elf

[destination_cpu=a53-0, exception_level=el-2] u-boot-zcu102-zynqmp.elf
}Building boot.bin can be accomplished with:
bootgen -arch zynqmp -image bootgen.bif -o boot.bin

The bootgen_utility is a tool used to dump the contents of a Boot Image generated by Bootgen, into a human-readable log file. This is useful in debugging and understanding the contents of the different header tables of a boot image. More at the documentation.

!!! note
The part listed in datasheets is sometimes different from the one that can be used in Tcl scripts. E.g.:
- ZCU102:
- datasheet: XCZU9EG-2FFVB1156
- part: xczu9eg-ffvb1156-2-e
To figure things out, use vivado “get_parts” command and match the closes. E.g.:
get_parts xczu9eg*
xczu9eg-ffvb1156-1-e xczu9eg-ffvb1156-1-i xczu9eg-ffvb1156-1L-i xczu9eg-ffvb1156-1LV-i xczu9eg-ffvb1156-2-e xczu9eg-ffvb1156-2-i xczu9eg-ffvb1156-2L-e xczu9eg-ffvb1156-2LV-e xczu9eg-ffvb1156-3-e xczu9eg-ffvc900-1-e xczu9eg-ffvc900-1-i xczu9eg-ffvc900-1L-i xczu9eg-ffvc900-1LV-i xczu9eg-ffvc900-2-e xczu9eg-ffvc900-2-i xczu9eg-ffvc900-2L-e xczu9eg-ffvc900-2LV-e xczu9eg-ffvc900-3-e
