Re: PB555 and Codewarrior

Hey guys,

These are my EPPC linker settings:
Code Address: 0x003fa000
Data Address: 0x003fc000
RAM Buffer Address: 0x00000000
ROM Image Address: 0x00000000
Heap Address: 0x00000000
Stack Address: 0x003ff000

EPPC Target Settings:
Small Data: 8
Small Data2: 8
Heap Size: 4
Stack Size: 4

With these settings established, the program exception for the 
init_registers went away. However I got another Machine Check 
Exception at:

/*
 *	branch to main program
 */
	
#if defined(USE_FAR_ADDRESSING_TO_TEXT_SECTION)
	lis      r3,main@ha      //Machine Check Exception 
occurs         
	addi     r3,r3,main@l
	mtlr     r3
	blrl

Now I believe I have setup all the memory initialization within the 
chip, but I'm not sure why there is yet more of these exceptions.
Anyone can help?

Thanks in advance,
Lei
