Hello,

I am using TMS570LS20USB Board and IAR 6.30.1.33127 compiler

I wrote a floating point handler as

__irq __arm void TsFlpHandlerAssist1(void)

{

}

When i compiled i get the following error -

Error[Pe147]:
          declaration is incompatible with
          "__interwork __softfp void TsFlpHandlerAssist1(void)" (declared at
          line 175 of
          "C:\PROGRA~1\TMDX570LS20SUSB\IAR630\HALCoGen\sys_vim.h")

Please let me know why i am restricted from using the __irq & __arm? Also kindly suggest some way to tackle it.

Thanks & Best Regards,

How about remove __ARM since somewhere in your code define it as __interwork (support both Thumb and ARM)?

Hello Weng,

It is solved.

This was due to the fact that i had the declaration in sys_vim.h as

extern void TsFlpHandlerAssist(void);

whereas in the definition in xx.c had it as

#include "sys_vim.h"

__fiq __arm void TsFlpHandlerAssist(void);

{

}

This can be solved either by removing the #include "sys_vim.h" from the xx.c file

by changing the declaration in sys_vim.h as extern __fiq __arm void TsFlpHandlerAssist(void);

Sorry for the confusion.

Thanks for your hints too.

With Best Regards,

Renjith George
