AR1443EVM-010: Unable to use the Hardware Trigger

Hello Konstantin,

The RadarStudio version you are using seems to be an older version.

My suggestion is to use the download the use latest MMWAVE-SDK  for the demo application and also move to latest MMWAVE-DFP .

Raghu

Hi Rangu,

thanks for the reply.
About Flashing the new Firmware in Radar Studio: Using the dfp_00.06.00.00, I had to load the following Files on the EVM:

BSS FW <inst_dir>\mmwave_dfp_00.06.00.00\firmware\bss\ar12xx_bss.bin
FSS FW <inst_dir>\mmwave_dfp_00.06.00.00\firmware\mss\binary_ram\ar1xxx_mss.bin
Config File <inst_dir>\mmwave_dfp_00.06.00.00\firmware\ar1xxx_config.bin

What are the equivalent Files in dfp_00.07.00.04? The new files look quite different.

Cheers,
Konstantin

Konstantin,

Are you able to find the files?

The files can be found in below location:

mmwave_dfp_00_07_00_04\firmware\radarss\xwr12xx_xwr14xx_radarss.bin

mmwave_dfp_00_07_00_04\firmware\masterss\xwr12xx_masterss.bin

mmwave_dfp_00_07_00_04\firmware\masterss\xwr12xx_memswap.bin

Hi Rangu,

thanks for the reply...should have looked this up in the User Guide....sorry for that.

I'm now using the Radar Studio v1.7.4.0

Flashing the firmware was successful regarding to the script message, even so it was surprisingly fast (took less than 1 second)

I do now configure the hardwaretrigger using  the SensorConfig tab in Rader Studio, which is possible in v1.7.4.0

Nevertheless the Hardwaretrigger seems not to work yet.

If this information is of any help: The revision of my chip is ES1

EDIT: I just found out that R165 is missing on my AR1443EVM 010...i'll let you know if adding r165 this solves my problem

Regards,

Konstantin

Konstantin,

Are you providing the external pulse to the SYNC_IN pin of the EVM? Also you will need to mount the R165 for the SYNC_IN to work.

The pulse duration needs less than or equal to the frame periodicity set in the frame configuration.

Also please plan to move to ES2.0 devices for latest updates and support.

Thanks,

Raghu

Thanks for reply!

>Are you providing the external pulse to the SYNC_IN pin of the EVM? Also you will need to mount the R165 for the SYNC_IN to work.

as i mentioned earlier I connect the output of a signal generator to the Pins J4.9: (40PIN_SYNC_IN) and J4.4 (GROUND) of the AR1XXXEVM-012 via a 30cm coax-cable. The gap at R165 is closed now.
This alone didn't solve my problem yet.


>The pulse duration needs less than or equal to the frame periodicity set in the frame configuration.

So the hardwaresignal gotta be faster than the initially configured periodicity...got it. Is there in any documentatoin ahw-trigger-usage-guide?
Anyway this didn't solve it.

I Also found the thread "AWR1243BOOST: hardware trigger" on the TI-forum with a very simular Problem. Vivec answerd in that thread "After you do the frame config with hardware trigger selected you need to click on "tigger frame" once for the device to set all the pin configurations. After that you can do setup TSW1400 and ARM TSW and provide a SYNC_IN pulse. "
I also tried this, but still no measurement. Is this even the right thing to do?

I also cannot measure any signal on the SYNC_OUT pin during a measuremnt. Is this something suspicious or does this pin never work?


>Also please plan to move to ES2.0 devices for latest updates and support.
I'll ask my contact if he can provide me some new hardware.
Anyway: is the HW-trigger function supposed to work with ES1.0? Has this ever been tested and confirmed?

Do you have another idea what i might be doing wrong?

Hello Konstantin,
Did this resolve your issue?

Thank you for your help Raghu.
There was definitlely some new information.
I' now waiting for die ES2.

Hi guys, i have TSW1400EVM, MMWAVE DEVPACK and AWR1642BOOST connected together. Software triggering has been working but i still have no luck getting the hardware trigger.

I am also wondering why you guys seems to be referring to SYNC_IN signals (that doesn't seem to be on TSW1400EVM) instead of EXT_TRG_INPUT, which is an SMA connector on TSW1400EVM?

"High Speed Data Converter Pro GUI" document (slwu087d) on page 16 ("3.1.3.3 Trigger Operation") refer to this input. Having said that i still have no luck getting the hadware trigger to work (1.8V pulse).

The sequence that i did was: change Trigger Select to Hardware trigger, click Set, then Setup TSW1400, then TSW1400 ARM, then Trigger Frame, then activate my 1.8V square wave signal (multiple pulse).

Questions: How does changing Trigger Select to Hardware trigger in Radar Studio affect Trigger Option in Data Capture Option in HIgh Speed Data Converter?-which is required to be ticked for hardware triggering as per slwu087d (or do they not talking each other?)-i believe these 2 softwares talk each other when Setup TSW1400 get executed?

Am i missing anything here?

Thanks

Regards

P.S
i also have a second set of TSW1400EVM, MMWAVE DEVPACK and AWR1642BOOST and planing to connect (using SMA cables) the SYNC1(or 2,3,4) of one to EXT_TRG_INPUT, of the other as illustrated in slwu087d
