Are there any other SPARCengine 1e users (6U format) that are using Wind
River's VxWorks real-time OS? We currently have several of these boards
which are currently made by SUN.
I have several problems that I am having trouble resolving thru Wind
River. For example:
1) VxWorks is shipped with the MMU only mapping 4 Megabytes of
local memory so the processor can access it. When I change the
initialization to map the 16 Megabytes that I have, it appears
that the VxWorks kernel complains (in kernelInit) when I tell it
that the system is now 16 Megabytes instead of 4 Megabytes. Has
anybody used these boards with VxWorks with more than 4 Meabytes???
I also have SRX boards which allows me to increase the memory size
by 64 Megabytes. It would appear hard for the MMU to be
initialized to access all this memory at the same time. Is it
possible to change the MMU in VxWorks on the fly instead of at boot
time?
2) I am attempting to communicate between two processors on the same
backplane but I am unable to read a memory location in processor
0 from on processor 1. What address should I be using on processor
1 and how should processor 0 be configured?
3) Has anybody used the backplane driver for the SUN 1e? I don't seem
to be able to get it to work?
4) Any comments on the soon to be released FORCE boards which are
copies of the SUN 1e but with improvements?
5) Is there a "distribution list" for users of VxWorks where questions
like this are asked?
Thanks for the help,
