OTA update problem with cc3200

Hi Suresh Vempalli,

Can you please provide the more details on where, and under what circumstance, you are getting this error?

And have you tried using the OTA example directly from the SDK and see if it works for you?

Thanks for reply,

     so i have tested get-weather example IT worked fine. And i developed application added OTA to it. It worked few times fine and suddenly it gives this error every time i update. I can only see above mentioned debug print. If i enable DEBUG_PRINTS it works fine. I am still testing with complete DEBUG_PRINTS i will post once cc3200 fails. So meanwhile can  you tell me what might be the problem here and what else i can do so that OTA doesn't fail again.

Can you tell me if any errors or any issues with current SDK OTA files. As We are going to mass production mode we need to solve this immediately. 

Please consider this as priority.

Thanks,

Suresh Vempalli 

Hi ,

I have some extra info

So my linker file memory values

   /* Application uses internal RAM for program and data */

   SRAM_CODE (RWX) : origin = 0x20004000, length = 0x22FFF // old 18fff

   SRAM_DATA (RWX) : origin = 0x20027000, length = 0x09000 //old 16000

       /* This code section is to use MCU Bootloader RAM section (16kB) */

   SRAM_BOOTLDR (RWX) : origin = 0x20000000, length = 0x0004000

Hi Suresh,

The message "[SOCK ERROR] -close scoket (83) ..." came from the SimpleLinkSockEventHandler async event handlers, location in file under /example/common/network_if.c for common usage for many SDK applications.
The asynchronous socket events are for notification and can be used to get the status/error reasons.

Please check the 'socket.h' file for possible type of 'SL_SOCKET_ASYNC_EVENT'.

Based on the two messages, you are receiving the async event:
#define RX_FRAGMENTATION_TOO_BIG (2) /* connectionless mode, rx packet fragmentation > 16K, packet is being released */

You should ignore this message since your are using TCP instead of UDP. This event applies to UDP only. Take a look at the handler in the SDK OTA example, such case is not being handled at all.

Hi,

 Thanks for reply,

 This error occurs after OTA Fail.

As i mentioned above when i do OTA First it gives me CdnClient_Run: Error - SaveFileChunk - (-15) and fails.

After that when try OTA again it gives me connectionless mode, rx packet fragmentation > 16K, packet is being released ERROR.

And OTA will not happen again.

Please let us know if any solution for this.

Thanks,

Hi Suresh,

The error came from the CDN (Content Delivery Network) client library that fails to save the retrieved file.

In fact, I don't really recommend using the CDN client library as this complex library is designed specifically for retrieving data from DropBox, and it occupies a large chunk in your application binary.

If you have a HTTP server running where you can host the ota files, you may simply use HTTP protocols to retrieve them, and then save the file by using the Filesystem library. This will significantly reduce the code size and complexity.

Thanks For info,

So i will try to do that.

my Another query is What is max file size specified in UNIFLASH 

is it SRAMCODE size

or is it complete code 

As u can see above unflash screen shot   max size is 143000

I tried with 230000 maxsize and it works fine.

So is it problem with max size or is it problem with CDN client????

waiting for reply

Thanks,

suresh

Hi Suresh,

The Max Size in the Uniflash is the file size. Please refer to the Uniflash Complete Guide for more information.
