PetaLinux开发流程

1. Create a new project

petalinux-create -t project --template zynq -n $(project_name)

or

petalinux-create -t project -s $(bsp_file)

2. Import hardware information

petalinux-config --get-hw-description=$(path_to_hdf)

The .hdf file is usually in $(project_name).sdk folder.

3. Create a new application

petalinux-create -t apps -n $(app_name)

4. Configure kernel

petalinux-config -c kernel

5. Configure rootfs

petalinux-config -c rootfs

Select modules/apps to be enabled.

6. Build

petalinux-build

7. Create BOOT.bin

petalinux-package --boot --fsbl images/linux/zynq_fsbl.elf --fpga images/linux/system.bit --u-boot --force

or

create a file, e.g., boot.bif, with

image : {
        [bootloader] images/linux/zynq_fsbl.elf
        images/linux/system.bit
        images/linux/u-boot.elf
}

And then, run command:

bootgen -image boot.bif -o i BOOT.BIN -w on

8. Boot file system from SD card

a) Change configuration

When reading hardware configuration

petalinux-config --get-hw-description=xxx

Select Image Packaging Configuration Root filesystem type (INITRAMFS) SD card

Or when configuring:

petalinux-config

Select Image Packaging Configuration Root filesystem type. Select SD card as the RootFS type.

petalinux-build
petalinux-package --boot --fsbl images/linux/zynq_fsbl.elf --fpga images/linux/system.bit --u-boot --force

b) Prepare SD card

cp /tftpboot/BOOT.BIN /media/username/BOOT/.
cp /tftpboot/image.ub /media/username/BOOT/.
sudo cp -a /path-to-compiled-rootfs/* /media/username/rootfs/.
