When a platform project is selected, or if it is in an empty workspace, the Vitis IDE will show the wizard with no initial values.įrom the Architecture drop-down list, select Zynq.Ĭlick Browse next to the Output BIF file path field. When a system project is selected, the Vitis IDE tries to generate an initial BIF for that project. You might see a different initial screen for the Create Boot Image wizard. The following table shows the memory address layout you will create in this example. Petalinux-package command uses 0x00520000 by default, you can keep using this address. However, because ZC702 has only 16 MB QSPI Flash, boot.scr needs to be modified to load it from around the 5 MB area. Assign boot.scr to this address during packaging.īy default, it is programmed in boot.scr that if the boot mode is QSPI, image.ub should be read from Flash offset 0x01000000 (16 MB). U-Boot reads boot.scr from Flash offset 0x00FC0000 by default. After the bootROM loads FSBL, FSBL can load bitstream and U-Boot properly and give control to U-Boot. The normal boot components can be packaged continuously. The device tree (read by the Linux kernel) The flat image image.ub which contains the Linux kernel In this example, you will not only package normal boot components, such as FSBL, bitstream, and U-Boot into BOOT.BIN, but also the The only difference is the BOOT.BIN packaging contents. The Linux kernel image and rootfs can be stored in the same QSPI as this example, or stored in another non-volatile form of storage such as an SD card, NAND Flash, or eMMC. QSPI Flash on a board normally has less capacity than an SD card or eMMC because of its relatively high price.

In this example, you will make a Linux boot image for QSPI Flash, write it into Flash, and let it boot. Itįinishes booting Linux on the target platform.Įxample 10: Booting Linux from QSPI Flash ¶ The U-Boot loads and starts the execution of the kernel image, the root file system, and the device tree from non-volatile RAM to DDR. Loads and executes the Linux U-Boot image from non-volatile memory to DDR memory The FSBL does the following:Ĭonfigures the FPGA with the hardware bitstream (if it exists)

The on-chip ROM code is responsible for loading the first stage boot loader (FSBL). The boot process is initiated by one of the Arm® Cortex™-A9 CPUs in the processing system (PS) and it executes on-chip ROM code.

Refer to the Zynq-7000 SoC Technical Reference Manual ( UG585) for more details. In this method, the master boot method is further divided into secure and non-secure modes. Different kinds of non-volatile memories such as QSPI, NAND, NOR flash, and SD cards are used to store boot images. In the master boot method, the CPU loads and executes the external boot images from non-volatile memory into the processor system (PS).
