HI all,

Is anyone have the opb_emac (no DMA) work with the kernel linux-2.6-xlnx from git.xilinx.com.
the message seams that it does work ,but the command ping return nothing!

Could you kindly suggest me what to do?

ps:

Hi Steve,

I think the booting message tell me that the interrupt line is connect OK,isn't it ?

and if you can tell me what should be care about in hard design and in kernel config with net?

Hi,All

I found out what the problem was from.
When i set the Bus clock frequency to 50MHz and Processor clock Frequency 200MHz, opb_ethernet does not work with the driver.

And i check the driver,don't find the code base on the frequency . Anyone knows the reason?

From the data sheet:

"The OPB BUS clock frequency must be greater than or equal to 65 MHz for 100 Mbs Ethernet operation and greater than or equal to 6.5 Mhz for 10 Mbs Ethernet operation"
