Sof file cannot be written.

[Yamada1]

As the title suggests, sof files cannot be written.

When the sof file is written, the following message appears and ends.

Error (209040): Can't access JTAG chain

Error (209015): Can't configure device. Expected JTAG ID code 0x02EE30DD for device 1, but found JTAG ID code 0x00000000. Make sure the location of the target device on the circuit board matches the device's location in the device chain in the Chain Description File (.cdf).

Error (209012): Operation failed

The device is recognized by "Auto Detect", and there is no particular abnormality in JTAG Chain Test.

Also, there was no difference between the device name detected by "Auto Detect" and the device specified in the design.

What are the possible factors?

It would be helpful if you could give me a hint to solve the problem.

Hi there,

There are some points I wanna make sure at first:

1. What is the series of your FPGA?
2. What is the failure rate for this issue (failed board/ total board)? 

The JTAG id 0x00000000 seems strange. Please try to change the line or port on your computer.

By the way, how you confirm “there is no particular abnormality in JTAG Chain Test”. It's also possible that the FPGA is damaged.

Best regards,

WZ

Thank you for your comment.

I'm sorry to trouble you, but I solved it by myself.

It turned out that the cause was that the response to the load of the core power supply was slow, so it was not able to respond to the current increase immediately after the end of sof writing, and the voltage was below the operating limit voltage.

Sorry for the trouble.
