Hi: I give my thanks to you at first.I did as your guides :Enable or Disable the interrupt using the assembly statement in C enviornment on the " CCS DSK C5000 1.22 " in the following : #include <board.h> #include <flash1.h> void main (void) { asm("SSBX INTM"); . . . asm("RSBX INTM"); . . . } but the bit "INTM" always could not be changed(through the register window) and there is a error information when invoke the assembler (version 3.50) ---" ERROR! at line 123: [E0002] Invalid mnemonic specification RSBX INTM". Why ? perhaps the environment is disturbed ? If the version is too low to work well,could I get free the high version ? The following is the Version for each tools on the DSK: TMS320C54x ANSI C Compiler Version 3.50 TMS320C54x ANSI C Codegen Version 3.50 C Source Interlister Version 1.20 TMS320C54x COFF Assembler Version 3.50 TMS320C54x COFF Linker Version 3.50 Please give me a answer as soon as possible ? Thanks a lot ! --------------------------------- |

liang, ther *must* be atleast one spoce after the first qoute in these statements asm ("<space>nop<spcae>" ); i think it will work derk -----Oorspronkelijk bericht----- Van: liang mar [mailto:] Verzonden: maandag 1 maart 2004 3:57 Aan: Onderwerp: [c54x] how to embed assembly Hi: I give my thanks to you at first.I did as your guides :Enable or Disable the interrupt using the assembly statement in C enviornment on the " CCS DSK C5000 1.22 " in the following : #include <board.h> #include <flash1.h> void main (void) { asm("SSBX INTM"); . . . asm("RSBX INTM"); . . . } but the bit "INTM" always could not be changed(through the register window) and there is a error information when invoke the assembler (version 3.50) ---" ERROR! at line 123: [E0002] Invalid mnemonic specification RSBX INTM".

Liang- > ther *must* be atleast one spoce after the first qoute in these statements > asm ("<space>nop<spcae>" ); > i think it will work Yes Derk is correct. Otherwise, the assembler will think that SSBX is a label: SSBX: INTM . . For the assembler, any non-comment text in column one is a label. -Jeff > -----Oorspronkelijk bericht----- > Van: liang mar [mailto:] > Verzonden: maandag 1 maart 2004 3:57 > Aan: > Onderwerp: [c54x] how to embed assembly > > Hi: > I give my thanks to you at first.I did as your guides :Enable or Disable > the interrupt using the assembly statement in C enviornment on the " CCS DSK > C5000 1.22 " in the following : > #include <board.h> > #include <flash1.h> > void main (void) > { asm("SSBX INTM"); > . > . > . > asm("RSBX INTM"); > . > . > . > } > but the bit "INTM" always could not be changed(through the register window) > and there is a error information when invoke the assembler (version > 3.50) ---" ERROR! at line 123: [E0002] Invalid mnemonic specification > RSBX INTM".

Dear Liang, I think you must put a space before a assembly instruction. Only the labels in DSP assembly can be written with no space in left. The assembly instruction must be as the following format: asm("<SPACE><Assembly Instruction>"); Best regards, Morteza Alizadeh liang mar <> wrote: Hi: I give my thanks to you at first.I did as your guides :Enable or Disable the interrupt using the assembly statement in C enviornment on the " CCS DSK C5000 1.22 " in the following : #include #include void main (void) { asm("SSBX INTM"); . . . asm("RSBX INTM"); . . . } but the bit "INTM" always could not be changed(through the register window) and there is a error information when invoke the assembler (version 3.50) ---" ERROR! at line 123: [E0002] Invalid mnemonic specification RSBX INTM".
