CC2540 F256 fails osal_snv_write/read functions

Other Parts Discussed in Thread: CC2540

Hi,

I recently changed CC2540 unit from F128 to F256. When I used F128 it worked fine. But as soon as I changed it to F256 it doesn't work for osal_snv functions (init, write, and read).

Please look below for what I did for changing from F128 to F256. If there is any missed step, please let me know.

C/C++ Compiler->Preprocessor->Defined Symbols: remove HAL_BOARD_F128

General Options->Target->Device information: change from CC2540F128 to CC2540F256

Linker->Config->Linker configuration file: change from ti_51ew_cc2540f128b.xcl to ti_51ew_cc2540b.xcl (checked Override default)

Thanks,

Brian

    Hello Brian,
    Which version of IAR are you using?

    1)

    You need to select device type in "General Options" from "CC2541F128" to "CC2541F256".

    2)

    Try "lnk51ew_cc2540F256_banked.xcl" instead or just disable "override default" in the linker configuration menu.

    Hi Eirik,

    Thanks for your answer. I'm using 

    IAR Embedded Workbench for 8051 IDE, including complete build chain and debugger. ver. 9.10.3

    IAR Embedded Workbench common components 7.0.6.3257

    Texas Instruments-BLE-CC254X-1.4.0

    1) I already did that (though I used CC2540F256 as I'm using CC2540).

    2) I tried "lnk51ew_cc2540F256_banked.xcl" and got below error.

    Fatal Error[e72]: Segment SLEEP_CODE must be defined in a segment definition option (-Z, -b or -P)

     I disabled "override default" but got same error.

    Can you please suggest me any other solution?

    Thanks,

    Brian

    Hello Brian,

    Seems like you need to use the linker file you used initially which includes the SLEEP_CODE segment where halSetSleepMode(void); is placed:

    $PROJ_DIR$\..\..\common\cc2540\ti_51ew_cc2540b.xcl

    Have you tried to run one of the example projects from the installer? If this works make sure to copy all settings to your project.

    BTW: IAR workbench 8.20 is recommended for BLEv1.4:

    e2e.ti.com/.../1402240

    Hi Eirik,

    I changed it back to ti_51ew_cc2540b.xcl and now it works. So strange.. Last time I used it, osal_snv_XX functions returned error but now it works okay..

    Anyhow, thanks to your support. Can you direct me to IAR workbench 8.20 download link? I tried but couldn't find it to download older version of IAR workbench.

    Thanks,
    Brian

    Hello Brian,

    Sorry, we do not have a link. You will have to contact IAR directly.
