OTA ISSUE for CC2538SF23

Other Parts Discussed in Thread: TIMAC, Z-STACK

Hi Ti,

there are 2 issues for my project about the OTA.

1:some time the download is failed at the end of the OTA, I debugged and found the image CRC is wrong, I don't know how this occurs?

if ( HalOTAChkDL ( HAL_OTA_CRC_OSET ) != SUCCESS )
            {
#if (defined HAL_LCD) && (HAL_LCD == TRUE)
              HalLcdWriteString ( "OTA CRC Fail", HAL_LCD_LINE_3 );
#endif
              return ZCL_STATUS_INVALID_IMAGE;
            }

2:some time it go to the next step when everything is ok and before reset the system it is wrong like below:

if (pMsg->hdr.status == ZSuccess)
    {
      // Reset the CRC Shadow and reboot.  The bootloader will see the
      // CRC shadow has been cleared and switch to the new image
      //Timac_Zstack_mode=0U;
     //osal_nv_write(WTM_IN_TIMAC_OR_ZSTACK_MODE, 0, 1, &Timac_Zstack_mode);
      HalOTAInvRC();
      SystemReset();
    }

I set the breakpoint in the SystemReset(), and it can not arrive here, but it can go into the function HalOTAInvRC();

so I think it is another CRC question.

sometime I just changed a little bit code and compile the .zigbee file for the upgrade.

Thank you can show me some information.

BR,

    Could you share what software stack you are using including the version and also which example project are you using as a base for your project.

    Thanks,

    Hi Hector,
    thank you for reply, the stack version is Z-Stack Home 1.2.2a.44539, and the end device is used the "SampleSwitch" sample and the Coordinator is used the "OTA_Dongle" sample.
    I think if this is happened, I think maybe the .zigbee file is broken otherwise it can not happen this.
    and my CPU is CC2538SF23, which only has 256K flash, and I have modification some of the flash mapping and now some time the OTA is normal but some time if I changed some code maybe it is not ok.
