CC3220SF-LAUNCHXL: ota failure

Hi,

I am getting some error in OTA process.

This is the log, I think it failed on first step only while initialization the OTA Library.

GEN:OtaInit: call Ota_init<\r><\n>
OTA_init: sizeof CdnClient=576, sizeof OtaArchive=9128<\r><\n>
OTA_init: sizeof OtaLib_t=11908, sizeof OTA_memBlock=7800<\r><\n>

The size of the OtaLib_t structure (defined in OtaLib.h) is too large.

You must have updated one of the buffer sizes that coposes the structure. Most of them are defined in ota.h (e.g. NET_BUF_SIZE(1440), MAX_URL_SIZE(512), MAX_VENDIR_DIR_SIZE(50), MAX_VENDOR_TOKEN_SIZE (96), MAX_SERVER_NAME(64) etc...). It should not add up 11908B (should be less than 7800).

you can also update OTA_BLOCK_SIZE (7800) to be more than the structure size, but i think the better way is to understand the definition that you updated and try to reduce it.

Hi,

Thank you for your reply.

The structure size I haven't changed it. I'm using same Ota code as earlier I have used.

I just change project name and project directory. This can cause any issue.?

Try to understand how the structure size got so large.

Hi,

I got the issue here, I was trying to update the @MAX_BUNDLE_CMD_FILES variable in OtaArchive.h from 8 to 15, that's why size of OtaLib got increase due to this variable. I have changed @MAX_BUNDLE_CMD_FILES to 11 and increase the little bit @OTA_BLOCK_SIZE to 10K, It's fine now.
