Even when I use MMU XLAT, I can't see the values of a skbuf, in net/core/dev.c (netif_rx) with DDD and BDIGDB
I don't know what to do.
I someone help me: I have a big issue with a AM29DL323GbB flash, I can read it, but can't erase or program it from ram whith ppcboot.
thanks
greg

Read the BDI2000 manual, especially the section about the PTBASE
config parameter.

Who ported PPCBoot to your hardware? Complain to him that he has
introduced a bug in the flash driver.

Hi,
I have some problem with the use of the bdi 2000 to debug linux kernel with DDD. In fact, I am connecting to the bdi2000 (target remote ....). And then, if I do step by step. But When I click on "step", DDD print: " error accessing memory access". And then, when I click again on "step" it steps. Is it normal???
Moreover I want to see the values in the structure skbuff in netif_rx. So I make a break point here, and then click on "continue". (As before I have to click twice because of the DDD message " error accessing memory access".)
It stops well on the begining of the function netif_rx, but I can't what there are in the values of the skbuff, I only see MAC=0,..., everything is NULL or 0!
Can someone has ever use the bdiGdb well?

I've never seen this happen. It doesn't sound normal.

seems like you have not enabled MMU XLAT in the configuration file of bdi.
check if the .cfg file contains the following lines, whithout an initial
semi colon.
MMU XLAT ;translate effective to physical address

Actually, I also have the same problem.
I tried to use SOFT break, and the problem seems to disappear.
Am I doing right?
Here is my configuration file.
BREAKMODE SOFT
MMY XLAT
BDIMODE AGENT
Thanks,
