Hello, all
I am a new user of the board TWR-MPC5125 made by freescale. Now I am trying to
porting the new kernel, i.e. the version 3.0.4, to this board. I have porting
the serial driver and the nand flash driver successfully. And I can also mount
the root file system. But I can not use the ether-net interface now. I have
tried to port the ether-net driver based on the ether-net driver for ADS 5121,
which is provided by the new kernel 3.0.4. The only thing I have to do in the
porting is that I should change the MII mode in ADS5121 board to RMII mode in
my board. And I find that I can send packages out if I use the "ping" command.
But I can not receive any package for responding. And I also found that the
interrupt routine for sending packages was running but the interrupt routine
for receiving message was not called by the kernel. I don't know why.
Can anyone help me? Should I change some other codes beyond the ether-net
driver? Someone told me that I should regulate the kernel because of the
differences among the different kerenl versions if the MAC was integrated
inside 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 interface
in u-boot and if using the kernel provided by freescale. Moreover, the u-boot
is also good and I have not change it. So the ether net pins are configured
correctly. But I have not porting the driver for DMA. But I think it is Ok
because the "ping" command can be used correctly if using the kernel provided
by freescale when I cancel the DMA driver when configuring the kernel.
Thanks.
