TDA4VM: QPENet board in the TDA4VM EVM board usage issue.

I followed the following guide 

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1040140/tda4vm-j7x-quad-port-eth-ethernet-extension-board-usage-in-linux/3860956?tisearch=e2e-sitesearch&keymatch=quad#3860956

I patched the ethfw and the linux kernel.It didn't work using my linux kernel and my app_remoteswitchcfg_server_strip.xer5f.But it worked on my linux kernel and app_remoteswitchcfg_server_strip.xer5f which is in the precompiled of zip file in the following link(i.e. ethfw_qsgmii_sdk7p1.zip):

My COM terminal shows 

Enabling clocks!
