LS1021A-TWR  - No ethernet devices under linux

Question asked by Vered Zvi on Jan 9, 2017



I built kernel 4.1.13 for LS1021A and ran it on the TWR. 

The root file system is busybox and the dtb is identical to the one used in Yocto project provided by NXP.


Under u-boot, all 3 ethernet devices work fine. 

Under linux, I can see only the "lo" device.

Is there any component I should add to the linux configuration ?


The 4.1.13 is a vanilla kernel from patched so I can run:

make ls1021a_defconfig 


Thank you,
