MT7620a OpenWrt barrier_breaker after compilation, the wan port dhcp cannot obtain the address
Preface

We are going to use openwrt barrier_breaker for secondary development. After the firmware is installed, we find that the wan port cannot be obtained through dhcp. After the following modifications, the mt7620a router can get the address normally.

Modify dts files

Change the pathOpenwrt/target/linux/ramips/dts/
Replace MT7620a. dts and mt7620a. dtsi with two files with the same name in Baidu cloud.

Modify the Makefile file corresponding to dts

Change the pathOpenwrt/target/linux/ramips/image/Makefile
