Hitachi H8 family. This port was done by Philip Quaife <philip@qs.co.nz> of Q Solutions and sponsored by Comnet Technologies Ltd. The port was done based on RTEMS 3.5.1 to a Hitach H8300H. The port was updated to RTEMS 4.5 style Makefiles/configure by Joel Sherrill <joel@OARcorp.com>. While doing this Joel added support for the h8300-rtems to binutils, gcc, newlib, and gdb. NOTE: Philip submitted a BSP for a Hitachi evaluation board which is being merged as a separate entity.

This port was done by Philip Quaife <philip@qs.co.nz> of Q Solutions
|
|
using RTEMS 3.5.1 under DOS and Hiview. Philip used an H8300H
|
|
to develop and test this port.
|
|
|
|
It was updated to 4.5 and merged into the main development trunk
|
|
by Joel Sherrill <joel@OARcorp.com>. As part of the merger, the
|
|
port was made to conditionally compile for the H8, H8300H, and H8300S
|
|
series.
|
|
|
|
The status of each CPU subfamily is as follows.
|
|
|
|
H8 - Although RTEMS compiles with for these CPUs, it does not
|
|
truly support them. All code that will not work on these
|
|
CPUs is conditionally disabled. These CPUs have a 16-bit
|
|
address space. Thus although a port is technically
|
|
feasible, some work will to be performed on RTEMS to
|
|
further minimize its footprint and address pointer
|
|
manipulation issues.
|
|
|
|
H8H - Port was developed on this class of H8 so there should be
|
|
no problems.
|
|
|
|
H8S - Port should work on this class of H8 but it is untested.
