    Usually I steal a piece of code that's about 5 instructions

    so I can do a

    LDR r3,=myroutine;
    MOV r15,r3


    then my routine executes, or i'll just edit some code.

    Recently I tried the callasm function and my function executed but died, yet I know the code works.

    What to do you guys do? Prefer?
     
    I dunno, cause I'm not quite that ASM savvy yet... Dunno how to do that...
    You sure you ended the routine correctly? (Just saying, cause everyone makes mistakes from time to time...)
     
    I haven't delved deeply enough into ASM to require editing of preexisting code but I'm thinking I'll end up using your method because it's so simple^^
    I assume that with your method you have to "recreate" the code that you overwrote with the 'ldr' and 'mov' in your custom routine?
