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 following: 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. Run targets to get the list of target processors.Įxample 10: Booting Linux from QSPI Flash ¶ Run connect to connect with the PS section. Open the Xilinx System Debugger (XSCT) tool by selecting Xilinx → XSCT Console. Note: This is the baud rate that the UART is programmed to onĭownload the bitstream by selecting Xilinx → Program FPGA, then Utility with the baud rate set to 115200.

Target board JTAG port with the following SW10 switch settings, as shown in Network or directly to your host machine.Ĭonnect the Windows host machine to your network.Ĭonnect a micro USB cable between the Windows host machine and the Itįinishes booting Linux on the target platform.Ĭheck the following board connections and settings for Linux bootingĮnsure that the settings of Jumpers J27 and J28 are set as described in Example 2: Setting Up the Board.Įnsure that the SW16 switch is set to 00000, as shown in the following figure.Ĭonnect an Ethernet cable from the Zynq-7000 SoC board to your Root file system, and the device tree from non-volatile RAM to DDR. The U-Boot loads and starts the execution of the kernel image, the Loads and executes the Linux U-Boot image from non-volatile memory to DDR The FSBL does the following:Ĭonfigures the FPGA with the hardware bitstream (if it exists) On-chip ROM code is responsible for loading the first stage boot The processing system (PS) and it executes on-chip ROM code. The boot process is initiated by one of the Arm® Cortex™-A9 CPUs in

Refer to the Zynq-7000 SoC Technical Reference Manual In this method, the master boot method is further divided into secure and non-secure Such as QSPI, NAND, NOR flash, and SD cards are used to store boot Images from non-volatile memory into the processor system (PS). In the master boot method, the CPU loads and executes the external boot
