Hi,

Did any one worked on the PPC405GP U-boot interrupt
controller? Mainly on the Ethernet UDP packets.

What is it you're trying to do? Interrupts will typically be disabled, 
and what does that have to do with UDP?

The interrupts *are* used on 4xx systems in the ethernet driver.

Good to know. Sorry for the noise. I wonder about the second part of my 
question, though.

It has nothing to do with UDP of course. Must be misunderstanding/mixup.

Hi  Stefan,

Thanks alot, yes it got mixedup...sorry...

I am going to use PPC405GP custom board, and in u-boot
I want to use one DMA Interrupt to transfer the data
from FPGA  to SDRAM memory. The same data need to
transfer to the host via Ethernet UDP packets without
using the Kernal.. Can I do...

Thanks
Raj

That's possible. You need to write some board specific code though.

Yes, that's possible too. Here too, you need to write new code to do this of 
course.

Hi,

Can you please guide me where I can bringup the
changes to that so that I willn't disturbe the tree of
the ppc4xx.

Best Regards,
Raj.

Such board specific changes should be implemented in your board directory. 
This way you will not "disturb" the common 4xx code. And you might want to 
add some board specific commands as well to support your functionality.

Stefan

Is this the original Walnut board you are using or a customized board that is 
similar to the IBM/AMCC Walnut?
