When using OTA, the allocation of data (LUT, FR_APP...) to external Flash is done automatically, is it possible to make it a user-specified placement?

This needs changes in how the app gets built and would need changes in the SDK.

If you want to change the location as to where the application and DCT data goes, this can be changed at /43xxx_Wi-Fi/WICED/platform/MCU/STM32F4xx/GCC/STM32F412/dct.ld

Now, even if you change this, the firmware needs to know as to when and where the required data is there and this is done during  the build and hence would need changes in SDK and may even need some changes in the firmware.

So, for further help, please contact your local sales partner.

I am going to update (OTA) a module that is set to "RESOURCES_LOCATION ? = RESOURCES_IN_WICEDFS" with a FW that is set to "RESOURCES_LOCATION ?= RESOURCES_IN_DIRECT_RESOURCES".

At this time, the placement of the external Flash data is not aligned correctly, so we would like to unify the placement before and after the update.
