Original question:

AWR1243 functional mode is not working

AWR1243: Problems with Funcitonal mode

Yuji Sugimoto
Intellectual 280 points
Part Number: AWR1243
Other Parts Discussed in Thread: UNIFLASH,

Our 1243 works properly when in Dev Mode, but we are unable to get the functional mode to work.
In Functional mode:
1) We are only able to achieve RS232 connectivity when the baud rate is 115200
2) We are unable to load the BSS and MSS files.
3) We are unable to "RF Power-up"
Error: Status: Failed, Error Type: RESP TIMEOUT
I am using mmWaveStudio 1.0.0.0
Thanks
YS

    In case of functional mode, you need to set jumpers on EVM for SOP-5 and flash xwr12xx_xwr14xx_radarss.bin，xwr12xx_xwr14xx_masterss.bin，xwr12xx_memswap.bin (from firmware folder of DFP) to AWR1243 using UniFlash.
    Post this step, set jumpers for SOP-4 (funtional mode) and then try from mmWave Studio. In functional mode you don't need to download MSS/BSS FW from this GUI, directly connect SPI and click RF power up button.


    Let me know if you face any issue after following these steps.

    Thanks for the reply.
    I haven't been able to actually flash using the UniFlash tool.
    I set to SOP-5 and try to flash, but keep getting the error: Not able to connect to serial port5. Recheck the COM port selected.
    I have made sure to set the COMPort to the one in the device manager set to XDS110 Class Application/User UART.

    I am using UniFlash 4.4.0

    Hello Yuji,
    In that case are you able to connect mmWave Studio on same COM port (COM5) in SOP-2 mode? just to make sure that this COM port is accessible.

    And may be you need to close mmWave Studio (to avoid any comflicting with this COM port) while using UniFlash or try to connect COM5 using TeraTerm/HyperTerminal/Serial-App to make sure that this COM port is accessible.

    There is no other blockage I can think for UniFlash to raise error while connecting COM5.

    Hi Jitendra,

    In SOP2 mode:

    mmWave Studio works perfectly and we are able to connect

    TeraTerm is also able to connect 

    UniFlash is not able to open COM5

    In SOP5 mode:

    mmWave Studio is sometimes able to connect RS232 using baud rate 115200

    TeraTerm is able to connect

    UniFlash is not able to open COM5

    Hello Yuji,
    Could you re-install UniFlash tool and then try?
    If this step also doesn't work then in the DFP installation you can find old version of mmWave Studio which supports flashing from it (mmwave/Radar Studio).
    <DFP installation>\rf_eval\radarstudio\RunTime\Radar Studio.exe, with this GUI set SOP-5 mode and choose User/application COM port , select MSS/BSS/MemSwap FW checkbox and click Flash button.

    Hi Jitendra,

    Thank you so much for continuing to help troubleshooting this. 

    I tried reinstalling UniFlash and using the web browser version of it and it was still not able to flash.

    I then used the DFP, Radar Studios to flash successfully in SOP mode 5. Unfortunately, after this and changing to SOP mode 4, I was able  to connect SPI but could not power up the RF. I keep getting:

    Failed, Error Type: RESP TIMEOUT
    [11:25:36] [RadarAPI]: ar1.RfEnable()

    Hello Yuji,
    Glad to know that you are able to flash to the device.
    Now, RF power up can fail for multiple reasons
    1. If flashed BSS firmware doesn't match with Silicon version. Do you have ES2.0/ES3.0 of AWR1243?
    2. In case of ES2.0 device, make sure that you have flashed all three firmware (xwr12xx_xwr14xx_radarss.bin，xwr12xx_masterss.bin，xwr12xx_memswap.bin) to the device. On SPI connect you should see different version in the GUI with and without firmware flash.
    3. Is power supply to device/board proper? [5V, 3-4A]
