hi gary,
u said that
"
On this hardware, it really doesn't matter. When you
reset the
processor, BR0/OR0 (chip select 0) is reset to map all
memory
onto the FLASH, thus 0x3400 is the same as 0xFA003400.
If you
patterned your startup code after what I've done for
the Adder
(I'm sure you did), then this is taken care of right
away.
"
so should i assume that when my Program counter(PC)
shows a jump from 0xfa000100 to 0x00003400 ... it is
actually a jump from 0xfa000100 to 0xfa003400.
becauz when i debug , my PC at 0x00003400 in place of
0xfa003400 but when i use a ROM based image the PC
moves to 0xfa00XXXX locations.
regards,
jasmine
