Hi AIM community,

I’d like to have the Ubuntu 18.04 or newer version supporting RSB-3720 A2 with the RTL8211FS PHY.  
On the wiki there is only the Yocto 3.0

Thanks,  
Chih-Chung

Hi Chih-Chung\_Hsieh  
Please refer the WIKI and build code script in Advantech WIKI/Github. The information include how to do porting new kernel (in Yocto) and package ubuntu.

Hi Chih Chung Hsieh

The new chip lan phy (RTL8211FS)driver is in Kernel. New version Kernel is compatible Lan Phy with AR8035 and RTL8211FS chip. You just only modify your kernel for your application.
