![]() ![]() ![]() Please refer to this page for more information on how to update the bootloader on your board. #Building u boot codeU-boot.imx can be copied to the tftp root directory /tftpboot/lynx/ with the following command: The development of U-Boot is closely related to Linux: some parts of the source code originate in the Linux source tree, we have some header files in common. Similar to many others, it provides the basic infrastructure to bring an SBC (single board computer) up to a point where it can load a Linux kernel and start booting your operating system. ![]() Edit the config. Building u-boot U-boot is the bootloader commonly used on our Allwinner SoCs. Once compiled, u-boot.bin can be copied to your SD Card. The former command selects the default XUELK configuration suitable for latest SBC Lynx targets (for additional defconfig please refer to the U-Boot defconfigs table above), while the latter builds the U-Boot binary image itself ( u-boot.imx). Now cross compile U-Boot using the Raspberry Pi Model B configuration: make CROSSCOMPILEarm-linux-gnueabi- distclean make CROSSCOMPILEarm-linux-gnueabi- rpibconfig make CROSSCOMPILEarm-linux-gnueabi- u-boot.bin. NOTE: this is the default configuration suitable for latest SBC Lynx target. Please build the dtc tool before proceeding with the steps described below. The API comprises access to block storage, network, and console to name a few. #Building u boot driversIt provides a stable API for the interaction of drivers and applications with the firmware. U-Boot depends upon an externally build device tree compiler (dtc) in order to build successfully. The Unified Extensible Firmware Interface Specification (UEFI) 1 has become the default for booting on AArch64 and x86 systems. enter the source tree directory and run the following commands: Building the U-Boot bootloader is a part of the Xilinx design flow described in Xilinx Open Source Linux.U-Boot depends upon an externally build device tree compiler (dtc) in order to build successfully. For BSPs older than V2. in case of needs you can update your local repository with the following git command Building the U-Boot bootloader is a part of the Xilinx design flow described in Xilinx Open Source Linux.Download 1 Download 2 Once the download is done, extract the tarball to /opt/toolchains/. Please note that this toolchain is for U-boot, there is another toolchain to build Linux kernel. open a terminal window and cd into U-Boot source code Toolchain Click one of the site to download toolchain to build U-boot.start the Linux development VM and login into the system.It is assumed that the development environment has been set up properly as described here.
