- Creating a Uniprocessor VxWorks Source Build
- Creating a CPU Based VxWorks Source Build
- Creating a VxWorks Kernel Image With Embedded DTB
5.内核配置截图
6.修改设备树的串口时钟,使用MZ702P板子,配置的串口时钟为100M
默认BSP的时钟频率为50M
- build project
build target - u-boot配置环境变量
=> setenv fdt_high 0xffffffff
=> setenv ipaddr 192.168.0.202
=> setenv netmask 255.255.255.0
=> setenv serverip 192.168.0.10
=> setenv bootargs ‘gem(0,0)host:vxWorks h=192.168.0.202 e=192.168.0.10:ffffff00 u=target pw=vxTarget f=0x00’
=> saveenv - uboot引导启动
tftpboot 0x5000000 uVxWorks
bootm 0x5000000
目前使用独立的DTB文件还不能正常启动。参考BSP目录下的readme文件就是使用独立的DTB文件,不能正常启动。
