I'm new to ARM RTX. So i tried to compile the example RTX_ex2 in the RL folder of keil.. Its default controller was LPC2129. It compiled with it. But mine is LPC2148. So I tried to change it. Now it doesnt work anymore. Even when i tried to change it back to 2129 it doesnt work. It shows following errors. Please help.
