MMWAVE-STUDIO: Issue with mmWave Studio: "Unable to read FPGA" Error with DCA1000 and AWR2944

Part Number: MMWAVE-STUDIO
Other Parts Discussed in Thread: AWR2944

Dear Texas Instruments Technical Support Team,

I am currently working with your mmWave Studio tool in conjunction with the DCA1000 and AWR2944 setup. Despite following all provided guidelines and instructions meticulously, I am encountering an issue where the software is unable to read from the FPGA, displaying the error message "unable to read FPGA".

We have confirmed that the IP address settings are correct, and we have also attempted to reinstall the drivers without any success. Before reaching out, we have gone through the following troubleshooting steps:

Ensuring that the firmware and software versions are compatible and up to date.
Checking all physical connections between the DCA1000, AWR2944, and the host PC.
Verifying the network settings and confirming proper communication between the PC and the DCA1000.
Reviewing the mmWave Studio documentation for any additional troubleshooting steps specific to this error.
Despite these efforts, the issue persists. I would be grateful if you could provide us with further guidance or any additional steps we might take to resolve this problem.

For your reference, here are the details of our system and the software versions we are using:

mmWave Studio Version: 03.01.01.00
Host PC Operating System:win10
Please let me know if you require any further information or if there are log files or system details that you need to better assess the situation.

Thank you in advance for your support and looking forward to your prompt response.

Best regards,

Dylan

    I would like to inform you that we have conducted a test with the firewall completely turned off to rule out any network-related problems. Unfortunately, the issue persists even after the firewall has been disabled.

    To reiterate, we are using FPGA version 2.9, and despite all standard troubleshooting measures, we have not been able to overcome the challenge we are facing.

    We are eager to receive any further suggestions or assistance you can provide. Your prompt response would be greatly appreciated as we are keen to resolve this matter swiftly.

    Thank you for your attention and support.

    Best regards,

    Dylan

    Hi,

    In these cases, you can try one of the below methods.

    1) Disabling the firewall.

    2) Re flashing the FPGA. 

    3) Check the baud rate you have set for UART communication.

    4) Check if all the cables and hardware is correct. 

    5) Try on a different PC/ Laptop to see if the issue persists.

    Thanks,

    Pradipta.

    Dear TI Technical Support Team,

    We have been diligently working to resolve an ongoing issue with our equipment, following the troubleshooting steps you kindly provided. Unfortunately, despite our best efforts, the problem persists. Below is a summary of the actions we have taken as per your suggestions:

    We have disabled the firewall to ensure it is not interfering with the communication.
    The FPGA has been re-flashed to rule out any firmware-related issues.
    We have verified the baud rate settings for UART communication to ensure they are correct.
    All cables and hardware connections have been double-checked for proper installation.
    We have also attempted to use a different PC/Laptop to see if the issue was specific to the initial computer.
    Despite these measures, the issue remains unresolved. To assist you in further diagnosing the problem, we have attached images of our hardware setup and screenshots depicting the software connection status.

    Additionally, we have noticed that the DCA1000 is exhibiting a red light indicator. Could you please provide us with some insight into what this red light might signify? Is there a particular error or condition that we should be aware of?

    We are eager to resolve this matter and would greatly appreciate any additional guidance or steps you might suggest.

    Thank you for your continued support.

    Best regards,

    Dylan

    Hi,

    The Red light on the DCA is not expected. I think it is indicating that the DCA is not operating properly as it is not able to read form the EEPROM memory. Hence you are not able to get this working. You will need to change to a working DCA.

    Thanks,

    Pradipta.

    Thank you for your prompt response.

    We understand that the red light on our DCA1000 indicates a malfunction, specifically related to the inability to read from the EEPROM memory. This insight is very helpful.

    Could you please provide us with detailed instructions or a reference guide on how to proceed with replacing the DCA? Additionally, if there are any recommended diagnostics that we can perform to confirm the EEPROM issue before we initiate the replacement, that information would be greatly appreciated.

    In the case of a replacement, could you also inform us about the process for obtaining a new DCA1000 unit? Are there any particular vendors or procedures that we should follow as part of your recommended practices?

    We aim to resolve this issue promptly and ensure our setup is operational as soon as possible. Your expertise and further assistance in this matter would be invaluable.

    Thank you once again for your support.

    Best regards,
    Dylan
