This process uses the U-Boot sources that have been board ported to the custom target board. More information about building U-Boot can be found here
A patch need to be applied to the U-Boot source tree for the given platform, AM335x or AM437x. This patch changes the default boot behavior to TFTP over either USB or ethernet.
AM335x - [U-Boot Patch to Add TFTP Boot Configurations]
AM437x - [U-Boot Patch to Add TFTP Boot Configurations]
Use the below commands to build the images from the u-boot source tree (assumes TI Linux Processor SDK 1.0):
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- O=flasher <build target from below table>
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- O=flasher
为什么uboot还要设置通过tftp从网口启动？
我们计划把flasher.sh集成到ramdisk文件系统后，自动运行flasher.sh，flasher.sh再通过tftp下载Production Image到emmc，这种方案可行吗？这么操作的话，uboot是不是可以就不用设置从网口启动？
明白了，谢谢解答，另外

这个patch（AM437x - [U-Boot Patch to Add TFTP Boot Configurations]）我们下载不下来，能提供下吗？我们现在用的sdk是
ti-processor-sdk-linux-am437x-evm-06.03.00.106-Linux-x86-Install.bin
