MT300A and OpenWRT 18.06 support

Technical Support for Routers

Hi All,
While building our firmware I noticed the following report from the builder.

Here are the issued warnings:

make[3] -C target/linux install
Pseudo file “/dev” exists in source filesystem “/work/firmware/MT300A/openwrt.18.06/openwrt-18.06/build_dir/target-mipsel_24kc_musl/root-ramips/dev”.
Ignoring, exclude it (-e/-ef) to override.

@kyson-lok maybe you can have a look.

@x-maysonnave The warning is caused by mt7620a.dtsi which is mt7620a generic header. Is there any exception for your firmware with the warning information?

Thanks for you feedback.
I face some stability issue with the 18.06 and tried to understand the root cause.
In my my current configuration dnsmasq doesn’t automatically start as it does with the 17.01 branch.
I made this report as I’m unable to analyse such low level warnings.
You’re in a better position than me to provide feedback to OpenWrt/Mediatek/Mips package maintainers.
Anyway our production firmware is 17.01 based.
Keep up your good work.

We will change to openwrt-18.06 on next release. Does dnsmasq not run automatically or it can’t assign ip address for client?
