AWR6843ISK: Infinite loop in Mcu_sysAPLLStatus()

Lungu Florin

Part Number: AWR6843ISK
Other Parts Discussed in Thread: MMWAVEICBOOST, , UNIFLASH, IWR6843

Hello,

I have some problems getting the MMWAVEICBOOST + AWR6843ISK running.

Hardware setup:

  1. Place jumper P4 (SOP2) + P6(SOP0) -> or flashing mode
  2. Connect USB XDS110
  3. Press Sw2 NRST
  4. S1 Switch mux config:  

            –       -- 

Software setup:

  1. Install the SDK from TI and locate the correct META_IMAGE: for AWR6843ISK

https://software-dl.ti.com/ra-processors/esd/MMWAVE-SDK/latest/index_FDS.html

                   

2. Chose the correct COM port (COM6)

               

 

 

3. Install Uniflash:

              https://www.ti.com/tool/download/UNIFLASH?keyMatch=UNIFLASH%20DOWNLOAD&tisearch=Search-EN-everything

4. Configure the Com port: COM6 and Device: mmWave – IWR6843 

5. Load the META_IMAGE

             

After that we removed the P4 (SOP2) ( SOP0 connected -> for functional mode), press NRST again and connect to the JTAG to load our application created using the MCAL mcal_01.04.01.00_GA

  • We observe the same behavior regarding the Mcu_init() topic (SPARE0 reg )  
      •  
      •       

  • During Mcu_Init the application gets stuck in a while loop in Mcu_sysAPLLStatus().
    This is because toprcmREG->SPARE0(0xFFFFE1EC) has the value 0x0 and this value never changes.
    When is this value supposed to be changed? 

    Attached you find a screenshot with the register values.

    Hi,

    If you are debugging your image through CCS, please flash CCS debug binary from below location instead of MMW demo binary:

    C:\ti\mmwave_sdk_03_05_00_04\packages\ti\utils\ccsdebug\xwr68xx_ccsdebug.bin

    Thanks

    hello,

    I'm not debugging with CCS, I'm using Lauterbach debugger.

    I also try with xwr68xx_ccsdebug.bin and I have the same behavior.

    Thanks,

    Florin

    Did you verify if you are able to load and run OOB demo?

    Thanks

    Florin,

    Seems there is xwr6xxx_radarss_rprc.bin version mismatch b'n SDK 3.5 and MCAL 1.4.1. MCAL 1.4.1 was tested with SDK 3.4 CCSdebug binaries. 

    I will look into it and come back next week.

    Thanks

    Hi Florin,

    We have identified potential issue with Mcu_sysBSSDeassertResetUngateClock() sequence. We are reviewing the same and will come back tomorrow with the fix.

    Thanks

    Hi Florin,

    Since this is being discussed off-line, I will be closing this thread.
