uboot引导vxworks--t2080调试记录

技术交流微信：mucx459522889

开发环境： t2080rdb, uboot2015， vxworks7.0

还是vx7.0的更容易开发，有需要的可以找我

1. 《VxWorks_7_fsl_t2t4_BSP_Supplement_Guide__SR0620.pdf》描述：

实际上默认创建的vip，profile选项为none时，vip内核配置中是包含了INCLUDE_END选项的。所以在创建vip的时候最好就添加上PROFILE_DEVELOPMENT。

2. 内核参数

bootargs是一些网络参数设置

=> pri bootargs
bootargs=memac(1,0)b109304:vxworks h=10.0.14.213 e=10.0.14.116:ffffff00 g=10.0.14.1 u=vxworks pw=vxworks f=0x04

设置好ip地址，下载代码运行

=> pri ipaddr
ipaddr=10.0.14.15
=> pri serverip
serverip=10.0.14.213

tftp 0x2000000 uVxWorks; tftp 0xf000000 t2080rdb.dtb; bootm 0x2000000 - 0xf000000

=> tftp 0x2000000 uVxWorks; tftp 0xf000000 t2080rdb.dtb; bootm 0x2000000 - 0xf000000
