arch/arm/include/lpc214x and arch/arm/src/lpc214x:
These directories provide support for NXP LPC214x family of
processors.
- STATUS: This port is in progress and should be available in the
- nuttx-0.2.5 release.
+ STATUS: This port boots and passes the OS test (examples/ostest).
+ The port is complete and verified. As of NuttX 0.3.17, the port includes:
+ timer interrupts, serial console, USB driver, and SPI-based MMC/SD card
+ support. A verified NuttShell configuration is also available.
configs/us7032evb1:
This is a port of the Hitachi SH-1 on the Hitachi SH-1/US7032EVB1 board.
- STATUS: Work has just began on this port.
+ STATUS: This port is available 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 limited 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.
