!!!IMPORTTANT NOTE!!!: Since the WICED-SDK-4.1, after applying the patch, the memory map of Duo has been changed. See the following memory map. If you are going to deploy WICED applications and WICED DCT via the Particle bootloader, only if the Particle bootloader version is updated to 5 or above (by updating the Particle system firmware v0.3.0 or above, or by RBLink if you have), then you can apply the patch of the WICED-SDK-4.1 or above, otherwise, if it is running the older bootloader, it will not jump to run the WICED application. If the Particle bootloader version is below 5, please checkout other branch and apply the patch of the corresponding WICED SDK. The RedBear Duo supports Cypress WICED WiFi SDK by adding this add-on. The Duo IoT development kit has two boards, the Duo and the RBLink.
