Timing Behavior of Remote Update IP After Reset on Cyclone 10 GX (10CX150YF672E5G)

I am using the Remote Update IP with the Cyclone 10 GX FPGA, part number 10CX150YF672E5G. I observed that the Remote Update IP does not respond properly after reset until approximately 300 µs. I expe...

After successful configuration, I am reading the current configuration boot address. If it corresponds to the base image address, I then read the reconfiguration trigger conditions. These are expected to be all zeros after power-up.

In my project, based on the reconfiguration trigger conditions, I pass commands to load the application image.

The observed faulty behavior is that the current configuration boot address and the reconfiguration trigger conditions are not as expected, all bits are read as 1. I suspect that internal control register updates may be taking additional time, which could be causing this issue.
