I got tired of having strange clock rates (e.g. #define
CONFIGURE_MICROSECONDS_PER_TICK 52489) and drifting times-of-day with
the gen68360 BSP so I changed the way the programmable-interval clock
interrupt works. The new version will have some jitter in the intervals
between individual calls to the rtems_clock_tick routine, but the
long-term average will match the CONFIGURE_MICROSECONDS_PER_TICK
fixes some problems:
I found the problem which prevented opening 'dev/sci1' (the default
console) with the 'gensh2' (sh7045) BSP. Both SCI ports were being
initialized against the same minor device number: '0'. When I tried to
open minor-device '1', it naturally crashed. Fixing that one value in the
'sci_device[]' array solved the problem and allowed 'hello.exe' to run.
report by Nick.SIMON@syntegra.bt.co.uk:
TFTP uses UDP and UDP packets are prime targets for getting dropped when
the network gets busy. I want the number of retries quite large in my
application. I see that PACKET_REPLY_MILLISECONDS is, in fact, not
being used.
functionality. This puts RTEMS in near compliance with the network
functionality defined in the first draft of the EL/IX API. Comments
follow:
With the attached changes to the libnetworking/libc/Makefile.in, RTEMS
provides all the functions listed in section 4.14 of the EL/IX document
except:
socketpair
if_nametoindex
if_indextoname
if_nameindex
if_freenameindex
Some of the routines which get information from files may be of limited
use unless an application sets up the files somehow (TFTP/untar from
host, etc.), but at least RTEMS is pretty much fully buzzword compliant
with the networking section of the EL/IX API.
in the dec21140 driver. Comments follow:
I have tried to use bootp with the dec21140 driver
and I had problems. I have found them
- Ethernet address must be known in Attach step
(read from the board)
- Endian problem for Ethernet address storage.
Now it is solved and I can use bootp to obtain
the network configuration of the target.
to generalize librdbg for all i386 BSPs. His comments:
The patch below generalizes librdbg for all i386 bsps. It is not a
complete rewrite, but a minimal invasive attempt to generalization.
To apply:

the patch:
Yes, or that other machine has a different chipset with different
timing requirements on enabling Gate 20. I am strongly suspecting
that it may some how related to the video card I am using (on my
old P-75 target it was plain PCI VGA, on my new one it is Diamond Stealth
3D 2000).
dec21140 drivers from the i386/pc386 and powerpc/mcp750 (all Motorola
PowerPC boards) and move the network driver to libchip. This driver
should work on all PCI based uses of this chip.
<corsepiu@faw.uni-ulm.de>:
The patch below provides
* automake support for score/cpu/powerpc
* The hack to propagate values from *.cfg to automake configuration
* A fix for librdbg/powerpc/mcp750/Makefile.am (Was completely corrupted
before)
* Fixes some files which apparently where missing in
rtems-rc-19991123-rc-2.diff
* some minor configuration related patches
To apply:
rm -rf ./c/src/exec/score/cpu/powerpc/wrap
patch -p1 < rtems-rc-19991123-rc-3.diff
Attention:
c/src/exec/score/cpu/[configure.in|aclocal.m4|configure] should be
removed after applying the patch.
Modifications had been made to the score/cpu/powerpc directory after
the snapshot this was based on. In particular, the mpc750 and
other_cpu directories had been renamed to new_exception_processing
and old_exception_processing. After this patch was applied, modifications
were made to account for this.
