1.1.4 PA-RISC Targets Supported

This supports the various boards manufactured by the HP-PRO consortium. This is a group of companies all making variations on the PA-RISC processor. Currently supported are ports to the WinBond ‘Cougar’ board based around their w89k version of the PA. Also supported is the Oki op50n processor.

There is also included, but never built an unfinished port to the HP 743 board. This board is the main CPU board for the HP700 line of industrial computers. This target isn’t exactly an embedded system, in fact it’s really only designed to load and run HP-UX. Still, the crt0.S and I/O code are fully working. It is included mostly because their is a barely functioning exception handler GDB debug stub, and I hope somebody could use it. The other PRO targets all use GDB’s ability to talk to ROM monitors directly, so it doesn’t need a debug stub. There is also a utility that will produce a bootable file by HP’s ROM monitor. This is all included in the hopes somebody else will finish it. :-)

Both the WinBond board and the Oki board download srecords. The WinBond board also has support for loading the SOM files as produced by the native compiler on HP-UX. WinBond supplies a set of DOS programs that will allow the loading of files via a bidirectional parallel port. This has never been tested with the output of GNU SOM, as this manual is mostly for Unix based systems.
