Hi, I'm using Sourcery G++ Lite 2008q3-72 tool chain for my application. I have written a sample code to print the stack and it is working fine, If I build using gcc [gcc (GCC) 3.4.6 version]. But the same code built using Sourcery binaries and when executed on ARM platform, it is not printing the stack contents. Could you please help on this regard? Regards.
