Retrieving usercode from binary configuration image

Hello Dave,

I must be misunderstanding.

Only a detail. There are two instances reading the image from the serial (or parallel) flash.

1. The RSU (remote sytem update) controller with enabled "pof checking" feature, optional Altera IP that provides a user interface to the hardware remote update block

2. The hardware configuration controller that reads the configuration image

The latter is always present, the former must be instantiated if you select "remote" configuration mode under configuration options.

The hardware ID check in application is another good way to avoid loading of a wrong FPGA image. Asking for failure safety in this point isn't paranoia, I think. It's even more demanding if the FPGA e.g. controls power electronic components.

Presently I'm exploring the available options in combination with the Altera remote system update concept. First results are promising.

Best regards

Frank
