more such cool stuff hereCS1 = 1, OE = 1, ADDR = X, DATA = Z.
CS1 = 0, OE = 0, ADDR = "".
OE -tOE> DATA = "";
CS1 -tCS1> DATA;
ADDR -tACC> DATA.
OE = 1, CS1 = 1, ADDR = X.
CS1 -tH> DATA = Z;
OE -tH> DATA;
ADDR -tH> DATA.
and you can now generate all those cool waveforms without having to worry about did you get the lines right etc..
For all the Beagleboard fans out there, we’ve created an evaluation version of Flash Lite 3. This is a fully functional version of Flash Lite that times out in 3 minutes. It is built on Angstrom Linux distribution and requires X. Please email me if you are looking for more information or are interested in having one. I should mention that OMAP 3530 (ARM Cortex A8) is a powerful CPU and seems to handle graphics as well as video very well."
1) Get Valgrind source code from SVN using revision 9648 and 1888 for VEX
svn co -r 9648 svn://svn.valgrind.org/valgrind/trunk
cd VEX
svn update -r 1888
2) Download the patch here http://bugsfiles.kde.org/attachment.cgi?id=32348
3) Apply the patch into the source code
cd valgrind
patch -p1 < [path to the patch]
4) Run autogen.sh to run autotools
5) Configure the source code
./configure --host=arm-angstrom-linux-gnueabi
The patch still has some bugs such as CPU instruction alignment you can 'cat /proc/cpu/alignment' to find out if the kernel is configured to fix unaligned accesses, and you can enable it by executing 'echo 2 > /proc/cpu/alignment' but it's enough to use for simple application.
Have fun with Valgrind :-)
PLATO is a tool for displaying and analyzing software traces from an application being debugged. It connects to TTIF (libttif.so, included) which provides a lower overhead replacement for printf(), so as to minimize the chance that timing related bugs disappear when you enable debug traces, and also some binary trace APIs. PLATO can be running on a separate PC from the application being debugged, making it suited for embedded development. PLATO will decode/filter/display/visualize the traces
