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. + +--joel +28 June 2000 |
