... I have some questions regarding the VERA software from Princeton and also the IXP12EB (revision B) in general...
The IXP12EB (Rev. B) that was supplied by Intel currently boots either VxWorks or Angel/UCOS. Currently, we're booting the hardware with the VxWorks_Gig binary image found in the IXP SDK 1.3. My university does not have the Tornado IDE for VxWorks or the VxWorks RTOS itself. Are these software absolutely necessary for me if I'm using the VxWorks OS?
Yes, I believe so.
If I use the libixprouter package with the VERA software on the IX12EB, would that be like substituting VxWorks and Tornado with Linux and VERA?
Yes.
What's the difference between developing microcodes for the stand-alone IXP12EB with the original Intel VxWorks image and the IX12EB with VERA?
Because the StrongARM would be running libixprouter, the interface between the microengines and the StrongARM will be different.
Will it work with microcodes compiled on the IXP SDK ver. 2.0 Linux Edition?
In general, no. I think an analogy would be writing x86 assembly language for Windows and for Linux. The code runs on the same processor and some subroutines would port with no changes; however, code which interfaces with the OS (the StrongARM) would have to change.
I hope you can help answer some of my questions or direct me to some resources which maybe of some help.
The ixp1200 mailing list is a good place to start for ixp1200/VERA questions. Scott
Thanks for the quick reply Scott. What's the difference between setting up the system with libixprouter and VERA and plugging it into the PCI slot of a motherboard with a host processor and just flashing the boot ROM with Cygmon and booting a Linux kernel image on the original Intel chassis as shown at http://www.netwinder.org/~urnaik/ixp1200_howto.html ? Also, are there any archives of the IXP1200 mailing list which I can go through. This would give me a clearer view of the picture much faster and maybe avoid asking questions which may have already been asked before. :) Thanks! "Real programmers don't document.
