intel-corei7-64 is a MACHINE name used by meta-intel and doesn't mean that it is specific to i7. You can use this machine value for Atom. > > Q2: What is the latest version of the kernel supported for Atom > E3845, can you give me the refer link? in the former refer link, the > kernel version is 4.14.18, can i modify it to 5.0? I'd request that you try out the latest 4.14 on warrior (or 4.19) instead of 4.14.18 from rocko and report back if you see issues. linux-intel doesn't have a 5.0 recipe since it's only based on LTS kernels. You can switch to using 5.0 linux-yocto kernel though when using warrior branch: PREFERRED_PROVIDER_virtual/kernel = "linux-yocto" > > Q3: I found that the kernel code was retrieved from > https://github.com/intel/linux-intel-lts.git, is there any > difference bettween intel kernel (geted from github.com/intel/linux- > intel-lts.git) and official kernel(download from www.kernel.org)? linux-intel carries Intel specific patches and backports that aren't part of stable/mainline kernel. > > Q4: what is the difference between these branch ?

If you compare the branches, they should be same.
