Hello! We have Motorola Sandpoint with PPMC8240 and MontaVista Journeyman 2.0. Budget constraints do not allow us to have a full version of MontaVista Linux and I am trying to find some ways to do kernel debugging with the Journeyman version of linux-2.4.2_hhl20.
We need to perform some measurements on a network card driver. Ideally, it would be great to obtain executuion traces (on the machine instruction level) of different components of that driver (eventaully with timestamps) and also (probably indirectly) measure DMA exchanges between the network card and RAM. Setting breakpoints is also desirable. Journeyman apparently does not have KGDB support and I would highly appreciate your advice on how such measurements / trace construction can be done (besides using occiloscope or printouts and pencil). It's the first time I am trying to get deep into the kernel so any of your suggestions/references would be very helpful. Thank you, Viktor ** Sent via the linuxppc-embedded mail list.
