hi
I build one osbdm-jm60 based on freescale's public release. IT seem some strange problem on coldfire v2.
I use my custom mcf52259 development board which can be debugged by tblcf BDM.
but when use my custom osbdm-jm60 bdm, sometimes the followwing error occured:
I build 'INTERNAL_RAM' target, click 'debug' button, then the code download into mcf52259 ram correctly. but when I run the target, it seems frozen, I means it stop at the beginning of _startup function:
asm void _startup(void)
{
/* disable interrupts */
move.w #0x2700,sr
/* Pre-init SP, in case memory for stack is not valid it should be setup using
MEMORY_INIT before __initialize_hardware is called
*/
lea __SP_AFTER_RESET,a7;
/* initialize memory */
MEMORY_INIT
/* initialize any hardware specific issues */
jsr __initialize_hardware
...................
BDM can't execute any code ,I press F10/F11, it stip at ' move.w #0x2700,sr', never go ahead.
I don't know what is the matter?what is the reason?
