Description: The pascal add-on does not work with the z16f (that is
configuration z16f2800100zcog/pashello). This appears to be
another ZDS-II error: when executing the instruction
SYSIO 0, WRITESTR a large case statement is executed. This
involves a call into the ZiLOG runtime library to __uwcase().
__uwcase is passed a pointer to a structure containing jump
information. The cause of the failure appears to be that
the referenced switch data is bad.
This is submited as ZiLOG support incident 81459.
Summary of ZiLOG analysis: "This is a ZNEO run time library problem.
One workaround is to replace the line 58 in uwcase.asm
From:
ADD R9,#4 ; Skip handler
To:
ADD R9,#2 ; Skip handler
And add uwcase.asm to the project.
If the customer does not want to modify uwcase.asm then the other
workaround is to add a dummy case and make it same as default:
case 0x8000:
default:
This will make sure that uwcase is not called but ulcase is called."
Status: Open. Due to licensing issues, I cannot include the modified
uwcase in the NuttX code base.
Description: Add support to maintain SPOV in context switching. This
improvement will provide protection against stack overflow
and make a safer system solution.

Title: ZDS-II COMPILER PROBLEMS
Description: The file drivers/mmcsd/mmcsd_sdio.c generates an internal compiler
error like:
mmcsd\mmcsd_sdio.c
Internal Error(0503) On line 2504 of "MMCSD\MMCSD_SDIO.C"
File <c3>, Args(562,46)
Status: Open. Recommended workaround: remove mmcsd_sdio.c from
drivers/mmcsd/Make.defs. There is no SDIO support for the Z16 anyway

Title: NATIVE BUILD PROBLEMS
Description: When last tested (ca.12/12), there were some missing .obj files in
arch/z16/src. A little additional TLC will be needed to get a
reliable Windows native build. As of this writing, the Cygwin
based build has not been re-verified.
Status: Open
Priority: Low -- I don't think anyone uses the Z16 port.

Description: There is no script for building in banked mode (more correctly, there
is a script, but logic inside the script has not yet been implemented).
It would be necessary to implement banked mode to able to access more

untested resolve logic.

Status: Open
Priority: Medium
Description: The first GET received by THTTPD is not responded to. Refreshing the page
from the browser solves the problem and THTTPD works fine after thatg. I
believe that this is the duplicate of another bug: "Outgoing [uIP] packets are dropped
and overwritten by ARP packets if the destination IP has not been mapped to a MAC."
Status: Open
Priority: Medium
Description: If the network is enabled, but THTTPD is not configured, it spews out lots
of pointless warnings. This is kind of annoying and unprofessional; needs to
be fixed someday.
Status: Open. An annoyance, but not a real problem.

o NuttShell (NSH) (apps/nshlib)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Description: The wget command has been incorporated into NSH, however
it is still untested as of this writing (only because I
have not had the correct network setup for the testing
yet). Since wget depends on the also untest uIP resolv/
logic, it is like non-functional.

Title: IFCONFIG AND MULTIPLE NETWORK INTERFACES
Descripton: The ifconfig command will not behave correctly if an interface
is provided and there are multiple interfaces. It should only
show status for the single interface on the command line; it will
still show status for all interfaces.

Title: READLINE IMPLEMENTATION
Description: readline implementation does not use C-buffered I/O, but rather
talks to serial driver directly via read(). It includes VT-100
specific editting commands. A more generic readline() should be
implemented using termios' tcsetattr() to put the serial driver
into a "raw" mode.

Priority: Low (unless you are using mixed C-buffered I/O with readline and
fgetc, for example).

Title: EXAMPLES/NX FONT CACHING
Description: The font caching logic in examples/nx is incomplete. Fonts are
added to the cache, but never removed. When the cache is full
it stops rendering. This is not a problem for the examples/nx
code because it uses so few fonts, but if the logic were
leveraged for more general purposes, it would be a problem.
Update: see examples/nxtext for some improved font cache handling.
Status: Open
Priority: Low. This is not really a problem becauses examples/nx works
fine with its bogus font caching.
Title: EXAMPLES/NXTEXT ARTIFACTS
Description: examples/nxtext. Artifacts when the pop-up window is opened.
There are some artifacts that appear in the upper left hand
corner. These seems to be related to window creation. At
tiny artifact would not be surprising (the initial window
should like at (0,0) and be of size (1,1)), but sometimes
the artifact is larger.
