I am using CW10.4 on Windows 8, it is my first time working with DSC and I found a very strange problem.
When I creat an empty Processor Expert project and directly run the project I got the following assembly code:
PE_low_level_init(); jsr 0x003a70
The address of PE_low_level_init() is 0xB8.
There will be an error: No source available for "0x454321 (0x454321)() "
I then found if I put something before PE_low_level_init, for example uint8_t i;
The assembly code:
adda #0x000002,SP PE_low_level_init(); cmp Y1,A X:(R0)+,C mpy A1,Y0,B A,X:(R0)+
The jsr is gone so the program can be executed but nothing initialized.
If I put uint8_t i = 0; before PE_low_level_init, the generated code is:
adda #0x000002,SP uint8_t i = 0; cmp Y1,A X:(R0)+,C add B,A A,X:(R0)+ PE_low_level_init(); jsr 0x0000b8
Another strange thing I noticed is that if I put
uint8_t msg[] = "hello world";
at the beginning of main.
Then read the variable in the debug mode.
I got : "he!\0o world\0"
Can any give a hint on that?
