I am using 128K SRAM (installed in Hardware CY62128 - External) in my 8052 project, and using only 64K RAM area as per my requirement (No - XBanking) :

Q1 : I need to properly clear 64K RAM area through software and run a test whether all locations in 64K area are Ok or not. What are the methods to follow?

Q2 : My code startup sequence is as follows...

	
		void main(void)
		{
			Initialize hardware devices
			Initialize RTOS
			Create Tasks
			Load default values and parameters
			start Interrupts and Serial Baud
			SuperLoop(); //Runs Forever...
		}

 

Is there any order to follow in the startup sequence? When should RAM be cleared?


Q3 : My otherproject hardware consists of 32K SRAM (62C256), and I need to clear the RAM through software techniques. What are the possible ways to do a thorough SRAM flushing?

I checked the all possiblilty of http://www.netrino.com/Embedded-Systems/How-To/Memory-Test-Suite-C and more ever it is working fine.

Is there any better suggestion than this?
