ZynqMP Petalinux Boot Generation

ZynqMP Petalinux Boot Generation

Note: enable xlnk module.

Prerequisite

​ source /media/embedded/d/lsq/petalinux/settings.sh

Create the Petalinux Project

​ petalinux-create --force --type project --template zynqMP --source /media/embedded/d/lsq/bsp/xilinx-zcu104-v2018.2-final.bsp --name proj1

Configure the Petalinux Project

​ cd proj1

​ petalinux-config --get-hw-description=path to your Vivado project sdk folder

This will bring up a configuration menu. Make the following changes.

* Under "Image Packaging Configuration" -> 
    "Root filesystem type" -> 
    Select "SD Card"
* Under "DTG Settings" -> 
    "Kernel Bootargs" -> 
    Un-select "generate boot args automatically" -> 
    Enter "user set kernel bootargs" -> Paste in the following line
        earlycon clk_ignore_unused earlyprintk root=/dev/mmcblk0p2 rw rootwait cma=1024M
* Save and exit the configuration menu. Wait for configuration to complete.

Note: “cma=1024M” means that the size of Contiguous Memory Allocator(CMA) is set to 1024M.

Patch a Bug

vim project-spec/meta-user/conf/petalinuxbsp.conf

Add the following line:

​ IMAGE_INSTALL_remove = "gstreamer-vcu-examples"

Build the Bootloader

​ petalinux-build -c bootloader -x distclean

Configure the Kernel

​ petalinux-config -c kernel

Enable xlnk module

• Enable staging drivers:

  Device Drivers → Staging drivers (ON)

• Enable APF management driver:

  Device Drivers → Staging drivers → Xilinx APF Accelerator driver (ON)

• Enable APF DMA driver:

  Device Drivers → Staging drivers → Xilinx APF Accelerator driver → Xilinx APF DMA engines support (ON)

Turn off CPU Idle and Frequency Scaling

• CPU Power Management->CPU idle->CPU idle PM support (OFF)
• CPU Power Management->CPU Frequency scaling->CPU Frequency scaling (OFF)

Modify the Device Tree for APF Driver

​ gedit project-spec/meta-user/recipes-bsp/device-tree/files/system-user.dtsi

Add the following entry at the bottom:

/{
 xlnk {
 compatible = "xlnx,xlnk-1.0";
 };
};

Build the Project

​ petalinux-build

Create the Boot Files

​ petalinux-package --boot --fsbl images/linux/zynqmp_fsbl.elf --u-boot images/linux/u-boot.elf --fpga images/linux/system.bit

Copy to SD Card

​ cp images/linux/BOOT.BIN /path to you boot partitation/

​ cp images/linux/image.ub /path to you boot partitation/

Note: BOOT.BIN contains the ATF, PMUFW, FSBL, U-Boot.
image.ub contains the device tree and Linux kernel.
