wl1271 calibration error - versions mismatch?

Hi,

I'm trying to run the calibration tool against the WL1271 device and I get the following when I run the calibrator utility.

# calibrator plt autocalibrate wlan0 /system/etc/wifi/wl12xx_sdio.ko /system/etc/firmware/ti-connectivity/TQS_S_2.6.ini /system/etc/firmware/ti-connectivity/wl1271-nvs.bin 00:00:00:00:00:00

Calibration not complete. Removing half-baked nvs

I've seen that this error suggests a mismatch between the firmware and driver. However I'm reasonably sure that I am using the firmware .plt file and driver that was pulled down using the TI script so they should be consistent.  The tag in the script is ol_R5.SP5.01.

I did a small amount of investigation on the versions and I get the following for the different components:

bluetree@bluetree:/home/wlan/compat$ git describe
ol_R5.SP7.01
bluetree@bluetree:/home/wlan/compat-wireless$ git describe
ol_R5.SP7.01
bluetree@bluetree:/home/wlan/wl12xx$ git describe
ol_R5.SP4.01-2-g1aa2c8e
bluetree@bluetree:/home/wlan/ti-utils$ git describe
ol_R5.SP4.01-1-g4951e94

This looks a bit strange given the tag is ol_R5.SP5.01 but perhaps this is to be expected and may have nothing to do with the problem.

Everything I've seen suggests this is due to a version mismatch but I believe the versions are consistent for the given tag.  Can anyone suggest what might be going on or ways to debug further?

Thanks,

Bruno

    Hi Bruno,

    As you suspected, "wl12xx: ERROR command execute failure 2" - indeed is a mismatch between the driver/calibrator/plt fw versions.

    The last wl12xx release is with git tag "ol_R5.SP7.01"

    It seems to me that the wl12xx driver & ti-utils git has not been updated to the latest.

    Please execute the build script at: https://github.com/TI-ECS/build-utilites/blob/master/wl12xx_build.sh (after modifying gen_tag to "ol_R5.SP7.01") and you shall have the the correct and latest versions for all the components.

    PLT should go through fine after this.

    Regards,
    Gigi Joseph.

    Just to close this off. It took me a while to get back to this but I eventually updated to ol_R5.SP7.01 and this fixed the problem. I am now able to calibrate the device.
