Hi, I run code(43xxx_Wi-Fi\otr_fr) on Sterling-EWB(Laird).

Is the OTA flash layout belong to internal flash?

My question is how to setup Internal(STM32F412 1MB)+External(2MB) flash layout for OTA? in DCT?

internal flash: bootloader / DCT / Current Application

External flash: FileSystem / APP0 / APP1

WICED version: 6.4

OS: ThreadX

Platform: GitHub - LairdCP/ewb_wiced_demo: Demo firmware for Laird Connectivity Sterling-EWB

Hello:

So what I considered is the OTA update image will be processed to external flash after filesystem.

You can calculate the size info after download to see if your flash size is big enough .
