External Flash with JN5179

We are planning to use 1 MB serial Flash with JN5179 to store older application image while OTA when newer Application image size is greater than 256 KB. So if it faces any difficulties with new Image it can load the previous one stored in external Flash?

 

1). Is external Serial Flash Supported with JN5179 which is not in the external Flash recommended list in the JN-UG-3118.

2). If supported how can we handle loading binary from external to internal flash in JN5179?

2). If supported, can we use external serial 1 MB or More size flash with JN5179? Because in JN-UG-3118 external flash supported with max size 512 KB.

3). Any application note available to access serial External flash which is not in recommended list serial flash list.

 

JN-UG-3118

 

Purpose behind asking this question is in JN-UG-3118 they have listed recommended external serial flash with MAX 512kB. So in this case it would be difficult to store two images in the internal/external serial flash, if existing and newer application size is greater than 256 KB.

 

Thank in Advance.
