<b>STATUS:</b>
- This port is in progress and should be available in the next release of NuttX.
+ This port is availble as of release 0.3.18 of NuttX. The port is basically complete
+ and many examples run correctly. However, there are remaining instabilities that
+ make the port un-usable. The nature of these is not understood; the behavior is
+ that certain SH-1 instructions stop working as advertised. This could be a silicon
+ problem, some pipeline issue that is not handled properly by the gcc 3.4.5 toolchain
+ (which has very limit SH-1 support to begin with), or perhaps with the CMON debugger.
+ At any rate, I have exhausted all of the energy that I am willing to put into this cool
+ old processor for the time being.

* Added port for the STMicro STR71x processor and configuration for the Olimex STR-P711

communicate with my JTAG wiggler on Linux).

* Began port of the Hitachi SH-1 using the SH-1/US7032EVB1 board
* Re-built all configurations that use SDCC and Zilog toolchains to make sure they still
build (they didn't, but they do now).
