CC1352P: Zigbee BIM/OTA Update

This link really doesn't seem answer my question.  I see the same hanging up of the download at 4%, but that's because there is no FN image in the external serial flash.

Here's the code in zcl_ota.c where it aborts.

/* Zigbee OAD assumptions:
* Factory New Metadata and binary image exist in external flash.
* Zigbee OAD will always take the next slot available after FN header and binary
*/

if(flash_open() != 0)
{
//Search for a metadata header to fit the Zigbee image
ExtImageInfo_t oad_imgHdrFactoryNew;

//OAD binary pages required to store the binary
uint8 binaryPagesLen = 0;

// Read the factory new metadata page
readFlash(EFL_ADDR_META_FACT_IMG, (uint8_t *)&oad_imgHdrFactoryNew, EFL_METADATA_LEN);

//is a valid header
if(memcmp(&oad_imgHdrFactoryNew.fixedHdr.imgID, oad_externalFLashID, sizeof(oad_externalFLashID)) != 0)
{
flash_close();
//This release does not support not having the Factory New image
return ZCL_STATUS_ABORT;
}

My question is how to get around this issue?

I did not provide the best link, this is the most relevant: https://e2e.ti.com/support/wireless-connectivity/zigbee-and-thread/f/158/t/763735

So you can choose to ignore the OTA header image validation or erase the existing external flash image with <SDK_DIR>/examples/rtos/CC1352R1_LAUNCHXL/easylink/hexfiles/offChipOad/ccs/erase_storage_offchip_cc13x2lp.hex (designed for the same external flash used on LaunchPads) and reference the "OAD with BLE" section of the rfWsnConcentratorOadServer example README which uses the BIM to copy the internal flash image to the external flash device for use as the factory image.

Hi Ryan,

Looks like this previous post was the same issue.  I went ahead and disabled the check and it does work.  I will look into the rfWsnConcentratorOadServer example to see how to create a factory new image.

--------------------------------------------------

We also see an issue in the code that we'd like a comment on....

There are two places in ota_client_app.c that have this #if statement... (around lines 441 and 804)

#if defined (OTA_STANDALONE) || (SWITCH_OTA)

This does not work.  Either it should be written like this:

#if defined (OTA_STANDALONE) || defined (SWITCH_OTA)

or

In the Properties-->Compiler-->Predefined Symbols use SWITCH_OTA=1

or

the containing code is not required and can be removed. 

We're choosing to do option 1, but would like verification that the code should be included.

Thanks,

- Bill
