Dan, Thanks for the pointers. I will try the dex-debug option. Just to clarify, I generally do not suspect the classes.dex (from core.jar) to be corrupt, because I copied this file in verbatim from the Android build environment. I did not rebuild this. I am able to run emulator version using the same core.jar.
Also I ran dexdump and it does not show any errors. Seeing the code for dexdump, it dumps only the class details (optionally the classdefs). As far as I understood the code, it was not parsing the type list. Also is there a standard procedure to build for glibc (one earlier posting talked about "lunch 2", but I think it is now not supporting glibc). Also as another experiment, I pulled the optimized cache file from emulator /data/dalvik-cache/sys...@framework@core....@classes.dex and copied into my ARM SoC and I got the following message
