MMWAVE-STUDIO: MMWCAS-RF-EVM calibration verification

MMWAVE-STUDIO: MMWCAS-RF-EVM + MMWCAS-.

Tool/software:

Hi,

I opened a ticket a few months ago regarding an issue I was having with the setup of the boards and mmWave Studio. When I first bought both boards (RF & DSP), they worked fine, but after some time, I was no longer able to connect to the RF board. After opening the ticket, you suggested it could be due to the power supply, but that was not the case (I am now using a 12 V / 5 A power supply). I temporarily fixed the issue by disconnecting the boards and the SSD and then reconnecting everything (or so I thought).

The very next day, I encountered the same problem again. After spending a lot of time troubleshooting, I managed to connect it again. However, I am now facing the same issue once more and am unable to establish a connection to the RF board. I really think something is damaged somewhere.

I have attached the log files from when I tried to run a Lua script and when I attempted to connect manually from mmWave Studio. Once I try to connect via SPI, everything crashes. I have also included pictures of the board, in case they are helpful.

Please, I need a solution. These boards are not cheap...

Best Regards,
Javier.

    Hi Javier,

    Sorry to hear of this. It seems to be an issue with the MMWCAS-RF-EVM. Assuming the connection and power are correct, we need to check for any HW issues.

    Could you try checking/reflashing the firmware following this thread: https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1395710/mmwcas-rf-evm-first-start-up-of-rf-dsp-evm

    I'm looping in a HW expert to advise on any other issues on the board. 

    Thank you,

    Jin

    Hello Javier,

    I am with the HW team. Please confirm if you still in assistance here. 

    Thanks,

    Hi,

    Yes, I still need assistance. I tried following the thread Jin suggested and everything seems okey.

    The image is correctle mounted in the ssd, I performed the write/read test and seems also okey. I also tried running apps_out mannually and interact with mmwave studio: everything looks goos until I click "SPI Connect" button on the GUI. I never receive anything in the apps_out script.

    Hello,

    I think we should check if the radar device is waking up properly. To do this, can you boot the primary device in SOP2 mode and probe the XTALP pin on R121. You should see a 40MHz clock signal.

    Next, probe (VBGAP) C2_1. You should measure 0.9V.

    If these are not correct it indicates an issue with the RF board and we would need to replace it for you.

    Regards,

    Adrian

    Hi,

    How can I boot the device in SOP2 mode? Just by choosing "Mode 2 (Development) and clicking "Set(1)"?. Anyway, this is what I did:

    Next, I probed R121 and this is what I am getting. It seems that the slock signal may be okey, but since I don't have a proper probe in order to be able to see a XTAL signal without disturbing it, I get a sine type signal. Does this make sense?

    Finally, C2_1 seems also okey:

    Regards,

    Javier.

    Hi,

    I kept debugging to see if something gives me (or gives you) any clue about what could be happening.

    This is the output I get in BUF_CLKOUT1 of LMK00804:

    And it is the same signal I have in 40M_BUF_IN_PRIMARY, which comes from AWR1_OSC_CLKOUT (default), so I guess oscillator for AWR1 is working fine.

    In 40M_BUF_IN_SECONDARY I am not getting any signal (coming from AWR_1_MCU_CLKOUT_RS).

    If I remove R121, place R116 & place R117, I am not able to see 40M_BUF_IN_PRIMARY anymore, coming from AWR1, I guess because I removed the path from Y1 to AWR1 by removing R121. But this makes no sense, considering this is the option for giving AWR1 another clock source...

    Hope you can help me somehow...

    Regards,

    Javier.

    Hello Javier,

    Based on your plots it seems like the radar board is waking up properly. Thus, I suspect there is something wrong with the DSP board. Please reach out to customer support to receive a replacement.

    You can also share a link to this thread if required.
