Subject: Port of EPICS 3.14.9 to ETRAX CRIS architecture - Strange Data
From: Peter Zumbruch <[email protected]>
To: [email protected]
Date: Wed, 22 Aug 2007 20:35:32 +0200
Hello everybody,

I am working on the port of EPICS to ETRAX CRIS architecture running Linux.
We are using several boards which either have Axis's chips:
ETRAX LX100 MCM (cris_v10)
(http://www.axis.com/techsup/dev/etrax_100lx_mcm/index.htm)
or ETRAX FS (cris_v32)
(http://www.axis.com/techsup/dev/etrax_100lx_mcm/index.htm)
as a control unit on-board.

I meanwhile have succeeded ( :-) ) in compiling EPICS 3.14.9 on a linux-x86 host-system for those two architectures:

- The CONFIG files needed to be create are documented at:
linux-cris_10:
http://wiki.gsi.de/Epics/ConfigurationEpicsCrossCompileLinuxCrisV10
linux-cris_32:
http://wiki.gsi.de/Epics/ConfigurationEpicsCrossCompileLinuxCrisV32
where exclusively linux-cris files have been modified/created.

   - Changes in CONFIG_SITE.linux-x86.Common:
       CROSS_COMPILER_TARGET_ARCHS = linux-cris_v10 linux-cris_v32

- The cross-compiler used is a gnu-compiler provided by axis:
cris-gcc --version: cris-axis-elf-gcc (GCC) 3.2.1 Axis release R64/1.64

- The file "$EPICS-BASE/src/libCom/osi/default/osdWireFormat.h"
has been extended by those two lines to comply for the little-endianness :

#elif defined (_cris_)
# define EPICS_LITTLE_ENDIAN


- The optimization -O3 had to be replaced by -Os or the default -O0 to be able to compile.

Also the example Application created via
   |$EPICS_BASE/bin/linux-x86/makeBaseApp.pl
|compiles ||meanwhile without problems.

Copied to the target system (cris_v10 Target) the IOC starts up thoroughly.
"dbl, dbpr, etc" applied to all given records seem to work.


But,
pardon me for the long introduction,
(either locally or remotely) looking with a client application to the the values the data are corrupted:

using *camonitor* gives for aiExample2
   (normally having a counter running  from 0 to  9):
