Petalinux in the QuadFlash

Former Member

Hi Everybody,

I'm new to Xilinx and Petalinux and I'm feeling a little confused about the images i can create with the Petalinux Utilities and which is the way i should download it to the flash in the Microzed 7010.

This is what i have done:

1. Install Petalinux
2. Create a petalinux project based in the 7010 bsp

Now in the .../image/linux/ folder i have a lot of images:

- image.elf
- image.ub
- rootfs.cpio
- rootfs.cpio.gz
- system.dtb
- System.map.lynux
- u-boot.bin
- u-boot.elf
- u-boot.srec
- u-boot-s.bin
- u-boot-s.elf
- u-boot-s.srec
- urootfs.cpio.gz
- vmlinux
- zImage
- zynq_fsbl.elf

My intention is to download and image or images to the quadFlash memory in order to start the linux that I already test in QEMU.

So, would you please guide me in the process to create the images i need to download to the board?

And about the bit-stream image, i also create a project for this specific board and exported the .bit file so i can use it for my system. Is there anything else i need to export to create the entire system images?

Thanks,

    Hi,

      You can use the petalinux-package command ( - - help or UG1144 or UG1157 for details) to create a BOOT.BIN image, which contains the first-stage bootloader, bitstream (optional) and u-boot.elf files.   This file and the image.ub  (which is a FIT image containing the kernel, device tree blob and ramfs) are all you need for booting PetaLinux on the target.

    By default, the PetaLinux configuration is targeted to SD card, so if you are targeting the BOOT.BIN and image.ub files to QSPI, you need to change the build configuration using the petalinux-config command to target the primary flash for the bootloader and kernel.  Then you can program the images to flash using the SDK, or u-boot sf commands if you prefer.
