Max10 RSU post config status
Hi,
Thank you for contacting intel community.
Per my understanding, you are using dual configuration IP with RSU.
What do you mean by erroneous status? Is there any error shown?
Have you refer to RSU userguide and also MAX10 userguide?
Regards,
Aiman

So I'm looking at the Dual Config Core registers at offset 5 and 6 which are defined as follow from the data sheet:
Specifically, I'm looking the Bit 3:0 in each register which defines what caused a reconfiguration of the device. If I understand correctly this would tell me in the event of some failure what caused it. The definition of these bits I'm taking from another part of the data sheet:
This is where the datasheet is confusing. As it seems the above table 13 is showing a status register from some internal logic in the device. Here I presumed that bits [31:28] which describe reconfiguration sources, are the same reconfiguration sources as in the Dual Config Core, just mapped into offsets 0x5 and 0x6 (bits [3:0] of the core avalon bus status registers.
I had presumed that these should all be 0 in the event of a successful RSU, which they indeed are when I cold boot the device. But on a warm boot, right after configuration, I seem to sometimes get a non-zero value on one or more of the 4 config sources (nconfig,crc error, nstatus, wdtimer), this is what I mean by erroneous status. But even here the device loaded successfully, so it looks like only a status reporting problem on a warm boot.
