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...

Hi Sumanth,

Thank you for your question. On the Cyclone 10 GX 10CX150YF672E5G, the Remote Update IP may not respond immediately after reset because the FPGA takes up to 830 µs to complete initialization and enter user mode (as specified in the datasheet). Accessing the IP before this time can cause issues.


Recommendation:
Wait at least 830 µs after reset, or use the INIT_DONE signal to confirm the device is ready, before interacting with the Remote Update IP. This timing can differ between device variants, so always follow the longer delay for compatibility.

 

Let us know if you have any further questions.
