Upgrading to 2024.1

Upgrading to 2023.2

Integrating VEK280/VEK280_es1 option

general:

• Changing dir structure for the upcoming baremetal ps_apps and vitis export flow

general:

• Adding the option to use the xpfm and/or linux pre-builds

general:

• Updated tutoral to 2022.2

platform/hw:

• Added lpddr4 to the base platform

general:

• Updated tutoral to 2022.1

platform/hw:

• Removed some ip and connections to end-up with the bare minimum base platform needed

  • Vitis nicely adds and changes IP and connections as required

• Exposed 1 extra clock via BUFG (clk_out2) next to the 4 exisiting clocks via MBUFGCE (clk_out1_o1-4)

  • id=0 -> clk_out1_o1 -> 500MHz

  • id=1 -> clk_out1_o2 -> 250MHz

  • id=2 -> clk_out1_o3 -> 125MHz

  • id=3 -> clk_out1_o4 -> 62.5MHz

  • id=4 -> clk_out2 -> 333MHz

linux:

• Added Yocto as alternative Linux build tool option with:

  • [project-root]/Makefile - export LINUX_BUILD_TOOL := yocto

  • [project-root]/Makefile - export LINUX_YOCTO_ROOT := ${HOME}/bin

  • Added [project-root]/linux/yocto

• Petalinux and/or Yocto TMP_DIR is now set and can be changed with export LINUX_TMP_DIR := /tmp/linux/${LINUX_BUILD_TOOL}

• Moved [project-root]/petalinux to [project-root]/linux/petalinux

• Moved [project-root]/petalinux/src/boot_custom.bif to [project-root]/linux/src/boot_custom.bif

• Moved [project-root]/petalinux/src/device-tree to [project-root]/linux/src/recipes-bsp/device-tree

• Moved [project-root]/petalinux/init-ifupdown to [project-root]/linux/src/recipes-bsp/init-ifupdown

• Linux build for export LINUX_BUILD_TOOL := petalinux ends up in [project-root]/linux/${BOARD_NAME}-versal

• Linux build for export LINUX_BUILD_TOOL := yocto ends up in [project-root]/linux/${BOARD_NAME}-versal and [project-root]/linux/${BOARD_NAME}-versal-meta

• Sysroot build for export LINUX_BUILD_TOOL := petalinux and export LINUX_BUILD_TOOL := yocto ends up in [project-root]/linux/sysroot

• Updated [project-root]/linux/src/device-tree/files/system-user.dtsi for proper Ethernet PHY configuration

• Added support for offline petalinux-build (Excluding sysroot build!) with:

  • export LINUX_BUILD_SOURCES := local

  • export LINUX_LOCAL_DOWNLOADS_DIR := /tmp/plnx-workspace/downloads

  • export LINUX_LOCAL_SSTATE_DIR := /tmp/plnx-workspace/sstate_aarch64_2022.1/aarch64

platform/sw

• Updated [project-root]/platform/sw/src/qemu/lnx/qemu_args.txt for adding Ethernet connectivity support (ssh/scp/…) for hardware emulation export TARGET := hw_emu

• Removed linux generated images dependencies; since NOT required

bif:

• Added [project-root]/linux/${BOARD_NAME}-versal/images/linux/Image and [project-root]/linux/${BOARD_NAME}-versal/images/linux/rootfs.cpio.gz.u-boot copy to the software platform to keep proper naming when export LINUX_BUILD_TOOL := yocto

• Added some dependencies so its only executed when needed

ip:

• Added vadd streaming kernels: mm2s_vadd_s -> vadd_s -> s2mm_vadd_s

• Renamed vadd to vadd_mm (vadd memory mapped kernel)

• Removed dependency on ${TARGET}; since NOT required

ps_apps:

• Added vadd_s to check the vadd_s streaming kernels

• Renamed vadd_cpp to vadd_mm_cpp to check the vadd memory mapped kernel

• Renamed vadd_ocl to vadd_mm_ocl to check the vadd memory mapped kernel

• Using explicit “kernel:{kernel_id}” for kernel selection

• Streamline print out messages

• Added dependencies on ${SYSROOT} and on ALL source files from ./src/*

vitis:

• counter and subtractor kernels running @ 500MHz (id=0 -> clk_out1_o1)

• vadd_mm (vadd memory mapped kernel) running @ 250MHz (id=1 -> clk_out1_o2)

• mm2s_vadd_s -> vadd_s -> s2mm_vadd_s (vadd_s streaming kernels) running @ 333MHz (id=4 -> clk_out2)

• Disable ILA when building vitis with export TARGET := hw_emu

• Added ${SYSTEM_CFG} as dependency for the Vitis Linker

• Added ${GRAPH_O} as dependency for the vitis linker, since you need to perform extra steps to be able to remove this dependency

• Added ${LINUX_IMAGE} and ${LINUX_ROOTFS} as dependencies for the vitis packager; and those are now taken from the software platform

general:

• Improved dependencies in almost all Makefiles to ONLY rebuild what is needed to be rebuild after a modification

• Added following [project-root]/Makefile commands:

  • make clean_vitis to clean everything (ip, ps_apps, vitis) after the (fixed) platform for the specified TARGET.

  • make all_targets to build everything for ALL TARGETS.

  • make ultraclean to clean everything for ALL TARGETS.

  • make ultraclean_vitis to clean everything (ip, ps_apps, vitis) after the (fixed) platform for ALL TARGETS.

• [project-root]/README.md updated with all new features

  • make all to build everything for the specified TARGET.

  • make clean to clean everything for the specified TARGET.

petalinux:

• Added the option LINUX_ETH_CONFIG to setup static Ethernet Configuration

ip:

• Bugfix for the v++ linker to fail in TARGET=hw_emu when other HLS-kernels (like mm2s) are added later on to the design

general:

• Adding the option to build for TARGET=hw_emu

petalinux:

• Improved petalinux version check

ip/aie:

• Optimized AI Engine Datamovers

general:

• Added more clarifications in the README.md
