Running multiple images from EPCS (Factory & User)

Jens, thanks for that, I think i now understand better how the system should work. I have a couple more questions if thats ok..

I've realised the main problem is that my Factory image does not properly initiate the altremote_update reconfiguration into the user image. I've spent the last few hours trying to work out how it should work and reading various manuals but can't get my head round it.

My quartus project for the Factory image is set to configuration scheme "Active Serial" and configuration mode "Remote", the User image is set to "Active Serial" and "Standard". Is this correct? I'm using the SOPC component linked in my previous post from jakobjones which provides a wrapper for the altremote_update block. I have set the altremote_update to use the operation mode "Active_Serial_Remote". This block contains a collection of functions for reading/writing from the block from the C code but i don't really know what they do.

I don't really understand how the various status registers of the remote_update block work

In the post you linked to you say:

To boot the application image we use the alt_remote_update function. The safe firmware image reads the remote_update status register. In case of power on (status = 0) the remote_update block is configured with the EPCS page address where the application configuration is stored and the watchdog activated. Then the reconfigure input is set to '1'.

This is what i need to do. Could you show me your code for doing these things (setting the EPCS page address, setting the watchdog, initiating reset etc)?

Thanks again,

Andy
