7. OCTEON Host Utilities
The OCTEON-SDK provides OCTEON host utilities which apply only to OCTEON or
Intel HOST architecture. For the LMP (Freescale) porting, however, the OCTEON-
SDK sources (OCTEON-SDK/host/remote-utils) can be accompanied into the LMP
source tree for cross compilation. There may be limitations in using assembler based
modules on the LMP.
SW7 configuration selects PCIe operation mode for each OCTEON processor.
“F_OCTEON Remote Control select Mode” or “S_OCTEON Remote Control select
Mode” should be selected to use this utility properly. Regarding SW7, please refer to
the aTCA-N700 Hardware User Manual, Section 4.1.2.
These utilities support the remote protocol using two PCI channels which are connected
to each OCTEON Processor. To select an OCTEON processor to be controlled by this
utility, an environmental variable needs to be setup before using the utilities, as shown
below
[ to select OCTEON TOP ]
# export OCTEON_REMOTE_PROTOCOL=PCI:0
[ to select OCTEON BOTTOM ]
# export OCTEON_REMOTE_PROTOCOL=PCI:0
