MAX10 RSU: Dual Config IP vs User Logic

--- Quote Start ---

Well, there's really no comparison because the dual configuration IP is required to even use the feature. See this online training and its follow-on for details:

Perhaps you mean using a Nios for controlling the IP vs. something like a user-designed state machine?

On page 13 of the MAX10 Configuration User Guide it states:

there are two methods to access remote system upgrade in intel max 10 devices:

• altera dual configuration ip core

• user interface

In addition there seems to be 2 "reference designs": One where a NIOS receives config data over a UART control the RSU process. This design uses the Dual Configuration IP core.

The second reference design has an I2C slave MAX10 device. In this design there is no NIOS in the slave and no Dual Configuration IP core. The slave device receives config data over the I2C interface and has user logic to manage the RSU process (using the fiftyfivenm_rublock module).

Both methods look like they manage dual compressed flash images. Apologies if I am missing something.

Thanks.
