We worked on PPC BSP, we booted Neutrino on a card (Interphase 4532)
based on MPC 8260 processor (Power Quick II) and we adapted successfully
serial port and Ethernet networking. We used the latest version of RTP
available on the Web. We have connected via LAN the PPC card and the
host PC (Pentium III) that we are using as development platform.
From the documentation it looks that it is possible to have processes
exchanging messages between the PPC and the Pentium, using low level IPC
and Qnet support, with the proper endian conversions performed within
the communicating processes.
To start the IPC the client has to find the pid of the server so we
expected that the namespace of any system is always available on the
Qnet network, also in case of different endianism.
We noted that the PPC namespace is correctly working from a shell
activated on the serial line of that processor, but when we attempt to
perform ‘ls’ of the /net mount point of both processors (Intel and PPC)
we got the “Unsupported endian” message referring to the other peer.
Is there anybody that could clarify the operation and the restrictions
of Neutrino in such cases ?
