H/W requirements for OTP RB-2

Recenetly, i tried the following configuration:

1) PPC860, 50MHZ, 32MSDRAM(32bits)

2) Vxworks 5.4

3) PPCLINUX with 2.4.19  kernel tree

My observation:

1) R10B-4 could run on the PPC860, both vxworks and linux
   But it is a bit slow, 

2) R7B is the fast one, with the small size of virtual machine
Eventually, i select to use the R9C-2, which isn't too slow, and looks like it will match my requirement.

I am going to start my project with the R9C-2 on PPCLINUX.

I guess it might be possible to run the R7B on the 16M SDRM, if compiled with uClibc. Not try it yet.

Best Regards
