LAUNCHXL-CC1352P: Z-Stack OTA doesn't start

Do you use sniffer to check what exactly happens over the air?

When I run the OtaServer, I see that Coordinator endpoint is 0x0E, Node Endpoint by default is 0xFF. I tried 0xFF, it didn't help too.

Also I tried "Broadcast Image Notify" but Image downloading didn't start.

I found a topic

https://e2e.ti.com/support/wireless-connectivity/zigbee-and-thread/f/zigbee-thread-forum/918108/cc2652r-cc2652-zigbee-ota-firmware-upgrade-issue-with-client

and I tried SDK 4.10.0.78, but it asked me about EndPoint instead of starting image downloading. But I see that that user didn't see the endpoint request.

I didn't modify the examples. I use them "as is".

I didn't find anything about entering Endpoint in the OTA User guide. Is it a new thing in the OtaServer? My version is 2.0.7. It should be okay. Why does it ask me to enter this and which value should I use?

Nothing changes. I see Data Requests and Ack every 3 seconds.

What value should I enter for EndPoint?

After reset I see that End Device sends periodical image requests every 10 seconds

1199    1274.853065    0xa939    0x0000    ZigBee HA    101    ZCL OTA: Query Next Image Request, Seq: 16

but image downloading doesn't start, although OtaServer says that "Image Found".

Can you provide sniffer log so I can help to check what happens?

Oh, there were wrong COM Port settings in the OtaServer tool.

By default it selects flow control RTS/CTS, but my USB UART converter doesn't support this.

Now it works, I set "None" for the flowcontrol.

But anyway, let me know what is the EndPoint request in OtaServer tool used for? What value should I type in the OtaServer when it asks me?

It's correct to use Endpoint 0x0E for OTA.

Hey Alex,

With the Application Builder update, Otaserver now only uses ZCL_OTA_ENDPOINT( currently 14). The windows application sends commands with the endpoint 20.  You can resolve this by changing the ZCL_OTA_ENDPOINT from zcl_ota.h to 20 for your Otaserver project.  This is being fixed in the v5.10 SIMPLELINK-CC13X2-26X2-SDK, however it is not expected to entirely break the OTA upgrade interface.  Please review the ZED switch OTA README and OTA Upgrade section of the Z-Stack User's Guide.  You can try to uncheck the “Version Check Image File” in the Options menu to see if the post-build steps with versioning are incorrect.  Did you program the ZED with the off-chip OAD hex image and the OTA binary file from the project's output folder?

Ryan

ok, thanks.

I found in the Z-Stack User Guide that

Quote: "In the current Z-Stack sample applications, this secondary storage is off-chip flash memory."

Is it still correct?

But I found in the topic
https://e2e.ti.com/support/wireless-connectivity/zigbee-and-thread/f/zigbee-thread-forum/918108/cc2652r-cc2652-zigbee-ota-firmware-upgrade-issue-with-client

Quote: "I used uniflash5.3.0 to erase the entire flash of CC2652 of another board,loaded cc26x2r1lp_bim_onchip.hex at first..."

So they used BIM_ONCHIP version.

How could it work if only off-chip flash memory is supported?

Hey Alex,

Great point, the on-chip BIM is not supported for Zigbee projects.  Off-chip must be used.

OTA was working and new image was uploading up to 100%, but ZED didn't restart, because I flashed bim_onchip instead of bim_offchip.

Then I flashed correct bim_offchip and erased the external flash with erase_storage_offchip_cc13x2lp.hex and now when I start OTA Server, I get ZOtaAbort.

Why does it stop downloading now? I didn't change anything else. Just changed bim and erased the flash.

Should I have something in the external chip to make OTA working?

I see the end request in the sniffer:

180    53.693860    0x90c9    0x0000    ZigBee HA    101    ZCL OTA: Upgrade End Request, Seq: 8

I found the post

https://e2e.ti.com/support/wireless-connectivity/zigbee-and-thread/f/zigbee-thread-forum/907135/cc2652r-zotaabort-no-factory-new-image

Does it mean that I can't use an empty external flash? Should I write the factory image first to have a legal image header inside the chip to start OTA, right?

Thanks, but when I add the defines

FACTORY_IMAGE
EXTERNAL_IMAGE_CHECK

in the zed_sw_ota_client project, I get build errors like

symbol "OTA_hasFactoryImage" redeclared with incompatible type:
symbol "OTA_saveFactoryImage" redeclared with incompatible type:

SDK 4.40.4.04, the project is not changed and imported "as is".
Only the defines were added in the Predefined Symbols.

Thanks, now it works
