Other Parts Discussed in Thread: SYSBIOS
When trying to use an user defined function to return the time from a RTC for the FAT filesystem under TI-RTOS, a problem occurs:
First, we add the pointer to our function as described in fatFS help:(http://127.0.0.1:52715/help/topic/com.ti.rtsc.SYSBIOS.product.ui/cdoc/ti/sysbios/fatfs/package.html):
var FatFS = xdc.useModule('ti.sysbios.fatfs.FatFS");
FatFS.getFatTimeHook = '&my_fattime';
But when building, we get this warning: missing return statement at end of non-void function "ti_sysbios_fatfs_getFatTime".
Because it is translated like this to code (return value from our function is lost);
Int32 ti_sysbios_fatfs_getFatTime(Void)
{
/* call user defined get_fattime() hook */
extern Int32 my_fattime();
my_fattime();
}
To solve this we had to add a 'return' statement in the the related function of FatFS.xdt file (located in C:\ti\tirtos_x_x_x_x\products\bios_x_x_x_x\packages\ti\sysbios\fatfs):
Int32 ti_sysbios_fatfs_getFatTime(Void)
{
%
% if (this.getFatTimeHook == null) {
%
return (0x23556622);
%
% }
% else {
% var getFatTimeHookName = this.getFatTimeHook.$name;
% getFatTimeHookName = getFatTimeHookName.replace(/\./g,'_');
%
/* call user defined get_fattime() hook */
extern Int32 `getFatTimeHookName`();
return `getFatTimeHookName`();
%
% }
%
}
Is this a bug on FatFS.xdt file that could be solved for next versions?
Thanks
