Error during Hardware Implementation

Hello,

I am using Terasic Agilex SoM Board.

In our custom hardware we are using AGFB014R24B1E1V device.

while programming .sof we are getting following error.

Device has stopped receiving configuration data.

Error message received from device: External hardware access error. (Subcode 0xC80E, Info 0x00000007, Location 0x00001800).

Error message received from device: The first I2C command has failed, no response from Voltage Regulator.

Debug suggestion: Verify the address used in Quartus project matches that of the Voltage Regulator, inspect the PMBus/I2C bus traffic, pull-ups, bus contention, etc. The 'info' field of this error contains the target I2C address.

Operation failed.

Could you please help us to find the issue.

Thank you.

    Hello,


    Few things you can do to troubleshoot.


    1. Validate the I2C address and bus connections.

    2. Check the I2C signal condition if the pullup is enabled.

    3. Probe the I2C bus for activity during configuration.

    4. Ensure the Voltage Regulator and power sequencing meet specifications.


    regards,
