Simon, Most likely the jmp takes you to an area outside of the scope of the current function. CodeWarrior for DSP56800's inline assembler does not support branch labels outside the scope of the current function. These kinds of tasks should usually be done in the standalone assembler which has a more feature-rich assembly language syntax and functionality. Hope this info helps!

I don't think it likes the "jmp" instruction. The following construct works: ((void (*)()) 0x1000)(); But it creates a stack frame followed by "rts" rather than using a "jmp". -----Original Message----- From: Simon Lightbody [mailto:] Sent: Friday, February 07, 2003 6:38 PM To: Subject: [motoroladsp] asm problem 56F803 Anybody got any idea on why this line won't compile (Codewarrior version 4)... asm(jmp $1000); If tried various combinations (0x1000, #$1000, #0x1000, etc.) Appears it might be a compiler bug...any ideas for a workaround? _____________________________________ Note: If you do a simple "reply" with your email client, only the author of this message will receive your answer.

Hello Simon, The same bug in Codewarrior v5 Workaround 1: // This behaves as jsr $1000 with 11 instructions (13 words) ((void (*)(void))0x1000)(); Workaround 2: // This behaves as jmp $1000 and takes 4 instructions (6 words) asm(move $1000,x0); asm(push x0); asm(push sr); asm(rts); Kind regards, Wim de Haan Exendis B.V.

Anybody got any idea on why this line won't compile (Codewarrior version 4)... asm(jmp $1000); If tried various combinations (0x1000, #$1000, #0x1000, etc.) Appears it might be a compiler bug...any ideas for a workaround?
