This board is based on the TI AM335x ARM Cortex-A8 CPU, clocked at up to 1GHz, and has a computing capability of up to 2000DMIPS. With DDR3, it is compatible with eMMC and NAND FLASH. Its bottom plate is a 4-layer board with Shenjin's lead-free process, which not only provides customers with The extensive AM335x introductory tutorial also assists customers in the development of the backplane, provides long-term and comprehensive technical support, helps customers to perform secondary product development at the fastest speed, and achieves rapid product availability.
1, install U-Boot source code
The U-Boot source code is "U-Boot\U-Boot source code\u-boot-xxx.tar.gz" on the CD-ROM, copied to "/media/tl335x/". Create the installation directory "/media/tl335x/u-boot" and unzip it to install it.
Run "mkdir u-boot" in the tl335x directory, create the u-boot folder, and extract the source code to the directory. The command is as follows:
Host# mkdir u-boot
Host# tar zxvf u-boot-xxx.tar.gz -C /media/tl335x/u-boot/
2 Clean U-Boot
Go to U-Boot's installation directory "media/tl335x/u-boot". Execute the following command:
Host# cd /media/tl335x/u-boot/
Host# make CROSS_COMPILE=http://
00.00.04-Linux-x86-Install/linux-devkit/sysroots/x86_64-arago-linux/usr/bin/arm-linu
X-gnueabihf- O=am335x_evm am335x_evm_config all -j 4
3 Compiling U-Boot
Execute the following command to compile U-Boot:
Host# make CROSS_COMPILE=http://
00.00.04-Linux-x86-Install/linux-devkit/sysroots/x86_64-arago-linux/usr/bin/arm-linu
X-gnueabihf- O=am335x_evm am335x_evm_config all -j 4
If the following error message appears.
Note The latest version of the device tree compiler is not installed. Execute the following instruction, and compile it again after successful installation. If no error occurs, ignore it:
Host# apt-get install device-tree-compiler
Linux operation alert: -j4 is a compile option and the CPU will use 4 threads for compilation.
After compilation, u-boot.img and MLO files are generated in the top directory of the U-Boot source code. As shown below:
