Hello everyone!
I've got a project for a HCS12-128 (MC9S12A128) and I want to load it into the same hardware but with a HCS12-256 (MC9S12A256). On the 128 works fine, but when I load it into 256 it won't pass the startup. The startup is the one created by the project wizard (for 1258). (Note, if it helps, I'm working with CW v4.6).
It gets stuck inside Init rigth after start execution. Here's a portion of it
static void Init(void) {
/* purpose: 1) zero out RAM-areas where data is allocated */
/* 2) copy initialization data from ROM to RAM */
/* 3) call global constructors in C++ */
/* called from: _Startup, LibInits */
__asm {
ZeroOut:
LDX _startupData.pZeroOut ; *pZeroOut
LDY _startupData.nofZeroOuts ; nofZeroOuts
BEQ CopyDown ; if nothing to zero out
When loaded into a 128 MCU, in the ASM window I see:
388000 LDX 0xC00D
388003 LDY 0xC00B
388006 BEQ *+16
Instead, when I load it into the 256 MCU:
388000 BGND
388001 BGND
388002 BGND
388003 BGND
Why is this happening?
I'm guessing it could be related to PRM file, so I attached it. With other projects I've done the same thing and I did not have any problem, and the only difference is that now I've touch the PRM from it's default.
Any input is appreciatted! Thanks!
