FreeRTOS on RL78/G14 with IAR (2.21.1) demo

This demo has been developped for EWRL V.1.xx. It cannot be compiled with EWRL V.2.xx.

I don't know of a port to work with EWRL V.2.xx

Please have a look at the Release Notes of EWRL. There is also a link to a document describing how to migrate a project from V.1.xx to V.2.xx.

I've found a way to write an IAR 2.21.1 compliant version of this assembly part looking the assembly dump of my serial port setup function :

       /* IAR 2.21.1 */

       ASEGN `.intvec`:CODE:ROOT,56

       DATA16

       DC16    _vPortTickISR

       ASEGN `.intvec`:CODE:ROOT,126

       DATA16

       DC16    _vPortYield

FreeRTOS is now working as expected ! :)

Hi,

with IAR v 3.10 the above declarations don't work

ASEGN `.intvec`:CODE:ROOT,56
DATA16
DC16 vPortTickISR

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

give the errors:

Error[Lp011]: section placement failed
unable to complete "place at" directives with a total estimated minimum size of 0x7c bytes in <[0x00004-0x00037]> (total space 0x34).
Error[Lp015]: section placement failure: overcommitted content in [0x00004-0x00037]
Error while running Linker

Has anybody tried to port Freertos for RL78 with 3.10 IAR Compiler?

Thanks
Nick

Why don't you simple use #pragma vector and __interrupt?
#pragma vector vPortTickISR=28
__interrupt void vPortTickISR(void);
#pragma vector vPortYield=63
__interrupt void vPortYield(void);

Hi Frank,

the portion of code I pasted comes from an assembly file.

I am sure there is a simple solution, I just can't see the assembly files generated by the compiler, therefore I cannot make a C file and check the correct syntax on the generated assembly file.
What is the assembly generated code from the #pragma def you suggested?

Thanks

Hello Friends,

I am also stuck in porting the FreeRTOS on RL78. I am using IAR version 4.2 and FreeRTOS 10.3.1 . Initially my demo code was for R5F100LEA(RL78_RL78G13_Promo_Board_IAR). I had the below lines.

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

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

but this was not getting compiled. So I changed the same

ASEGN `.intvec`:CODE:ROOT,56
DATA16
DC16 vPortTickISR

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

After compilation of the above the below error is coming. Please help.
