AtaSimpleIO incompatible w/ MemXAtari?

[Harry Potter]

Hi!  I saved about 2k of memory by converting my MadLibAtari code to use AtaSimpleIO instead of the standard I/O functions, but, when I run the program, it loads the stub files then crashes.  I believe the first thing it does is use AtaSimpleIO to print information.  I attached two files that may be causing the error.  Am I doing something wrong?

crt0_atari.s printc.s

When you have problems like this, you need to attach more than the 2 modules you suspect, the problem may be elsewhere.

Have you also not yet learnt to step debug in Altirra? If not then you should.

Okay.  Here are the main module and the code to load the stubs....

 

BTW, AtaDisk65 is a library to access the disk with less code than the standard library.

main.c readauxfile.c AtaDisk65.zip

Not your bug but "goto start;" a goto in a C program ?

May not be the bug, but this seems strange

 

        if (i==136) {
            k=*(unsigned char*)(0x348+16);  <<< 0X348 is in IOCB0 +16 takes it into IOCB1 which starts at 0X350 ???
            aux_memcpyto (j, auxbufx, k);
            break;

 

Also maybe it's just me, but you mix freely Hex and Dec numbers in the same equations/calculations.

Just a hint, it's also very useful to use system equates if possible

I found the problem: AtaSimpleIO was incompatible with the AtariXL: I forgot to enable the ROMs before each call and disable them afterwards.
