What sort of filesystem does this file contain? Do you have a skyeye.conf file? What address range does it load this file at? Regards Greg

I installed skyeye simulator for GDB/armulator. So which one are you actually using here? The trace below looks like GDB/armulator. On top of that i installed the uClinux distro also. While installing it dint throw any error. But while loading the uClinux in armulator it is throwing an error and the kernel is not booting. (gdb) run Starting program: /home/vinay/Documents/NS4Porting_Parvathy/scriptsAndPackages/uClinux-dist/linux-2.4.x/linux Please provide all the gdb/armulator trace up to this point.
