#14 main thread initialization error while running on xscale be

[Mike Kemelmakher]

Hi,

i tried to compile and run jamvm 1.4 on xscale be.

Following some system details

# cat /proc/cpuinfo
Processor : XScale-IXP4xx/IXC11xx rev 1 (v5b)
BogoMIPS : 263.78
Features : swp half thumb fastmult edsp
....

# cat /proc/version
Linux version 2.4.20_mvl31-ixdp4xx (a178722@A178722)
(gcc version 3.3.1 (MontaVista 3.3.1-3.0.10.0300532
2003-12-23)) #29 Sun Mar 27 14:06:5

JamVm was compiled using montavista toolchain,
xscale_be-gcc (GCC) 3.3.1 (MontaVista
3.3.1-3.0.10.0300532 2003-12-24)

And i'm trying to run apache-tomcat-5.5.12 + classpath
0.19 ...

classpath was compiled using jikes and same gcc like in
JamVm case.

When trying to run the whole thing on target i'm
getting the following output

#/usr/local/bin/java -verbose

Error initialising VM (initialiseMainThread)
===========================================

pointer values printing was added by me in thread.c
right after

823: /* findField and findMethod do not throw an
exception... */

it seems like there is some problem with vmData field ..
vmData = findField(vmthread_class, "vmData", "I");

any ideas ?
