AWR1642: XDS110 hangs when both two transmitting antennas enabled for one chirp

Part Number: AWR1642

Hi there,

I am using the xwr16xx mmw demo in the MMWAVE SDK 01_01_00_02. When I am setting that  both the two transmitting antennas transmit simultaneously in one chirp (chirpCfg 0 1 0 0 0 0 0 3), the console in CCS show that the sensor start successfuly first, but then the XDS110 hanged. I have tested that both 'chirpCfg 0 1 0 0 0 0 0 1' and 'chirpCfg 0 1 0 0 0 0 0 2' work perfectly. PS: channel configuration has been set to 'channelCfg 15 3 0' .

the following console output is given

CS_DAP_0: Error: (Error -261 @ 0x0) Invalid response was received from the XDS110. (Emulation package 7.0.48.0)

Cortex_R4_0: Error：  (Error -261 @ 0x0) Invalid response was received from the XDS110. (Emulation package 7.0.48.0) 

CS_DAP_0: Unable to determine target status after 20 attempts

CS_DAP_0: Failed to remove the debug state from the target before disconnecting.  There may still be breakpoint op-codes embedded in program memory.  It is recommended that you reset the emulator before you connect and reload your program before you continue debugging

Cortex_R4_0: Unable to determine target status after 20 attempts

Cortex_R4_0: Failed to remove the debug state from the target before disconnecting.  There may still be breakpoint op-codes embedded in program memory.  It is recommended that you reset the emulator before you connect and reload your program before you continue debugging

The dox has shown that maximum of only 2 TX can be turned in a chirp.

Any idea?

Thanks,

Beren

    Hi Raghu, 

    Following are my configuration,

    sensorStop

    flushCfg

    dfeDataOutputMode 1

    channelCfg 15 3 0

    adcCfg 2 1

    adcbufCfg -1 0 0 1 0

    profileCfg 0 77 7 7 58 0 0 68 1 256 5500 0 0 30

    chirpCfg 0 1 0 0 0 0 0 3

    frameCfg 0 1 32 0 100 1 0

    lowPower 0 0

    guiMonitor -1 1 1 1 0 0 1

    cfarCfg -1 0 2 8 4 4 0 5120

    cfarCfg -1 1 0 8 4 4 0 5120

    peakGrouping -1 1 0 0 1 224

    calibDcRangeSig -1 0 -5 8 256

    extendedMaxVelocity -1 0

    clutterRemoval -1 0

    compRangeBiasAndRxChanPhase 0.0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0

    measureRangeBiasAndRxChanPhase 0 1.5 0.2

    sensorStart

    I am using the profile_2d.cfg provided in the xwr16xx mmw demo and I replaced the oringinal chirp configuration with 'chirpCfg 0 1 0 0 0 0 0 3'.

    Thanks
