Hello,

I am using eclipse to debug program for ARM cortex M3. Could anyone help me to understand the errors

I might be talking complete rubbish but I think the default requriement is for 16Kb of working area. I think the working area is where OpenOCD places instructions to the processor and collects data from the TAPs. Correct me on any of these please as the manual is not explicit!

Anyway the MMU is only permitting you to map a value less than 16kB starting at the work area location specified. Look at the memory map. I think a good address to setup your working area is 0x2000 0000 on that chip, 16kb is 0x4000 for working area size.
