Hello,

Since two/three days I'm trying to update via the OTA, transition V1 to a V2 by modifying several things:

- transition from WICED5.1 to WICED6.1

- Using the mqtt protocol to communicate with a new server

- plus some minor modification.

However, I can not achieve this update and it seems that this is associated with the size of my file, which increases in large part by the use of mbedTLS Re: MBEDTLS occupies lot of memory space after an upgrade .

Binary file store in external file reach ~530ko (previously 390ko).

I tried to modify the wiced_apps.mk (tools / makefiles) and platform_dct.h (WICED / platform / include) files to enlarge the sectors without success.

Can you guide me to find a solution?

I read a some similar issues (seems to be solved but I do not understand why ?) :

OTA Slots as defined in ota_fr.c

Re: OTA upgrade problem

ota_fr fail @ grater size of update file than DCT_APP0 size

OTA upgrade without FR on 3.1.2

I believe you mean upgrade from sdk-5.1 to sdk-6.1 (sdk-5.2 is using mbedTLS).

I know the problem and I reported it quite long time ago.

I think you just cannot OTA to new SDK.
