imx6ul-c2修改设备树配置can引脚失败

各位好：
我按照文档修改设备树文件，如下：

1、linux_imx6ul_emmc_config 文件
http://mail.163.com/js6/s?func=mbox:getMessageData&sid=WCuLToPADTWwxSMWAlAAxFnFedFNeKkX&mid=68:1tbiRAkpAVSITasRggAAsM&part=3
file:///C:/Users/xyl/AppData/Local/YNote/data/ambitious_xing@163.com/6564627d8e7d4feb8432195c54d6ed28/clipboard.png

file:///C:/Users/xyl/AppData/Local/YNote/data/ambitious_xing@163.com/6564627d8e7d4feb8432195c54d6ed28/clipboard.png

file:///C:/Users/xyl/AppData/Local/YNote/data/ambitious_xing@163.com/6564627d8e7d4feb8432195c54d6ed28/clipboard.png
file:///C:/Users/xyl/AppData/Local/YNote/data/ambitious_xing@163.com/6564627d8e7d4feb8432195c54d6ed28/clipboard.png

2、/drivers/Makefile
http://mail.163.com/js6/s?func=mbox:getMessageData&sid=WCuLToPADTWwxSMWAlAAxFnFedFNeKkX&mid=68:1tbiRAkpAVSITasRggAAsM&part=4
file:///C:/Users/xyl/AppData/Local/YNote/data/ambitious_xing@163.com/9c468feee8cb4bb6a8b6c1c14cc134a4/clipboard.png
3、/derivers/net/can/Makefile
file:///C:/Users/xyl/AppData/Local/YNote/data/ambitious_xing@163.com/d80a918c753946c4a716953f82713405/clipboard.png
http://mail.163.com/js6/s?func=mbox:getMessageData&sid=WCuLToPADTWwxSMWAlAAxFnFedFNeKkX&mid=68:1tbiRAkpAVSITasRggAAsM&part=5
4、/arch/arm/boot/dts/imx6ul-14x14-evk.dts
file:///C:/Users/xyl/AppData/Local/YNote/data/ambitious_xing@163.com/02a6aed7d792417db290a07d562a996c/clipboard.png
http://mail.163.com/js6/s?func=mbox:getMessageData&sid=WCuLToPADTWwxSMWAlAAxFnFedFNeKkX&mid=68:1tbiRAkpAVSITasRggAAsM&part=6

5、/arch/arm/boot/dts/imx6ul-14x14-evk.dts


编译后替换dtb文件，重新烧录，重新启动时时发声如下现象，过一会屏幕黑屏。

http://mail.163.com/js6/s?func=mbox:getMessageData&sid=WCuLToPADTWwxSMWAlAAxFnFedFNeKkX&mid=68:1tbiRBorAVSITbrRxAAAsK&part=3

串口输出正常，点击屏幕串口也有输出。
请问我是哪里改错了？

源码以及环境都是使用飞凌自带的环境，我的目的就是想把自定义引脚配置成can通信引脚
