Hello, all

I am a new user of the board TWR-MPC5125 made by freescale. Now I am tr= ying=20 to porting the new kernel, i.e. the version 3.0.4, to this board. I have p= orting=20 the serial driver and the nand flash driver successfully. And I can also m= ount=20 the root file system. But I can not use the ether-net interface now. I hav= e=20 tried to port the ether-net driver based on the ether-net driver for ADS 5= 121,=20 which is provided by the new kernel 3.0.4. The only thing I= have=20 to do in the porting is that I should change the MII mode in ADS5121 board= to=20 RMII mode in my board. And I find that I can send packages out if I u= se the=20 "ping" command. But I can not receive any package for responding. And I al= so=20 found that the interrupt routine for sending packages was running but the=20 interrupt routine for receiving message was not called by the kernel. I do= n't=20 know why.

Can anyone help me? Should I change some other codes beyond the ether-n= et=20 driver? Someone told me that I should regulate the kernel because of the=20 differences among the different kerenl versions if the MAC was integrated = inside=20 the SOC, which was the fatto in my board. But I don't know how to regulate= .

B.T.W. : The hardware is good enough because I can use the ether net=20 interface in u-boot and if using the kernel provided by freescale. Moreove= r, the=20 u-boot is also good and I have not change it. So the ether net pins are=20 configured correctly. But I have not porting the driver for DMA. But I thi= nk it=20 is Ok because the "ping" command can be used correctly if using the kernel= =20 provided by freescale when I cancel the DMA driver when configuring the=20 kernel.

Thanks.

Guohu=20 Li
