Hello,

I've tried to compile and link demo project for RL78 micro called RL78RL78G13PromoBoardIAR. However new version of IAR cannot compile it. Following errors pops up in file portasm.s87 at lines from 101 to line 107, here is code snippet:

~~~~ COMMON INTVEC:CODE:ROOT(1) ORG configTICK_VECTOR DW vPortTickISR

COMMON INTVEC:CODE:ROOT(1)
ORG 126
DW vPortYield

~~~~

and here are error messages:

Error[As078]: Directive COMMON not supported in ELF mode. C:UsersjohnDesktopfreertos-masterFreeRTOSSourceportableIARRL78portasm.s87 101 Error[As078]: Directive ORG not supported in ELF mode. C:UsersjohnDesktopfreertos-masterFreeRTOSSourceportableIARRL78portasm.s87 102 Error[As078]: Directive COMMON not supported in ELF mode. C:UsersjohnDesktopfreertos-masterFreeRTOSSourceportableIARRL78portasm.s87 105 Error[As078]: Directive ORG not supported in ELF mode. C:UsersjohnDesktopfreertos-masterFreeRTOSSourceportableIARRL78portasm.s87 106

Could you please advise what shall be done in order to compile and link this project. I've tried with older version of IAR and it compiled well.

Version of FreeRTOS is FreeRTOSV9.0.0rc1, downloaded from sourceforge, unfortunatelly I cannot find revision number.

From your post it sounds like the latest compiler version is not compatible with previous compiler versions. Please see if IAR provide an upgrade guide and report back what you find.

I couldn't find any specific upgrade tutorial, I've noticed however that documents EWRL78_AssemblerReference.ENU.pdf differ with each other in regard to chapters which are called :

Segment control directives ( old compiler version)

and

Section control directives ( new compiler version )

On renesas forum I found also some post from a guy with similar problems.

Should I consult with IAR guys regarding to those problems. I'd really try to do this on my own but I'm not familiar with IAR compiler and stuff. Thank you for response by the way.

Wait, maybe I found some documents, which are telling about migration, it's called:

EW_MigrationFromUBROF.pdf

I'm just starting to read it.

Sounds promising. Please report back any findings or solutions.

Regards.

I found a workaroung using absolute sections:

ASEGN `.intvec`:CODE:ROOT,configTICK_VECTOR
DATA16
DC16    _vPortTickISR

ASEGN `.intvec`:CODE:ROOT,126
DATA16
DC16    _vPortYield

I have changed my code as Nayden Isapov said, but I got these errors, how can I resolve them?
