Download a pre-built snapshot image from https://images.solid-run.com/LX2k/lx2160a_build

Those images are built with the suffix of the commit ID of the https://github.com/SolidRun/lx2160a_build  project that you can clone and build by yourself.

You can build your own image using the script in here – https://github.com/SolidRun/lx2160a_build

Plug a micro SD into your Linux PC, the following assumes that the micro SD is added as /dev/sdX and all it’s partitions are unmounted.

unxz lx2160acex7_2000_700_....img.xz
sudo dd if=lx2160acex7_2000_700_...img of=/dev/sdX

Booting the micro SD and flashing to either eMMC, NVME M.2 or SATA drive

1. Make sure that the kernel is booted with the following variables in the command line –

   Code Block
   language bash
   default_hugepagesz=1024m hugepagesz=1024m hugepages=2 isolcpus=1-15 iommu.passthrough=1

   If using the above installation of Ubuntu then the /extlinux/extlinux.conf file should look as follows (the default installation with the addition of isolcpus=1-15 iommu.passthrough=1) –

   Code Block
   TIMEOUT 30 DEFAULT linux MENU TITLE linux-lx2160a boot options LABEL primary MENU LABEL primary kernel LINUX /boot/Image FDT /boot/fsl-lx2160a-cex7.dtb APPEND console=ttyAMA0,115200 earlycon=pl011,mmio32,0x21c0000 default_hugepagesz=1024m hugepagesz=1024m hugepages=2 isolcpus=1-15 iommu.passthrough=1 pci=pcie_bus_perf root=PARTUUID=30303030-01 rw rootwait

2. From build/dpdk directory under the lx2160a_build project, search for dynamic_dpl.sh and testpmd files and copy them over to the LX2160A Ubuntu root filesystem

3. Run the following that will generate 10Gbps traffic on dpmac.10 using only a single core. Can be used to generate traffic on dpmac.1 and other interfaces –

dynamic_dpl.sh dpmac.10export10
export DPRC=dprc.2testpmd2
testpmd -c 0x3 -n 1 -- --txd=1500 --txpkts=1500 --tx-first --auto-start --forward-mode=txonly --stats-period=10
