IWRL6432: Reading data in ESP32

Does sensor comes with preinstalled drivers. If not, how to flush that? Can it be flushed using below board

Hello,

Can you clarify what you mean when you say 'without TI development board'? Do you already have a custom design with IWRL6432?

Regards,

Josh

Hello Josh,

We have our own customised PCB, We can see all voltage seems to be correct. We also followed below document and however we not able to flush the libraries. The device itself not showing when we open from TI software.

We used below USB to UART to connect to sensors.

Thanks

Thanks Josh for the response. 

We ttried that option already. We are using mac, do you think that causes the connectivity issue. Do you want us to try with windows?

Also, can you cross check the module we are using for UART too USB, is it the correct one?

Also, can you confirm which UART pors required to be connected to sensor for flash?

Thanks

Karunakar

We purchased IWRL6432BDBAAMFR sensor and which evaluation board design do we have to follow for PCB.

IWRL6432BOOST
IWRL6432AOPEVM
IWRL6432FSPEVM

Thanks

Karunakar

Our PCB. is designed by taking design files of IWRL6432FSPEVM

Hi Karunakar, 

From your new post here:  IWRL6432AOP: Facing issue in connecting iwrl6432  

I see you are still having issues connecting even on a windows PC. Do you mean you do not see the com port at all or you do but still can't connect in the visualizer?

Regards,

Josh

Hi Karunakar, 

Please keep the discussion for this topic in this thread. You mentioned:

"We tried with exe you have shared, still we not able to see sensors on any of the COM ports" 

Can you let me know exactly which exe you are referring to? Can you clarify what "see sensors on any of the COM ports means"? Please send a picture of your Windows Device Manager if possible. Do you mean that nothing changes when you plug in the FT232RL board (no ports show up)? If so, this is not related to the radar device at all. You may need drivers for that board specifically, it appears to be an FTDI device based on the link you shared. You may need to download the drivers from the FTDI website. 

Regards,

Josh

Hi Josh,

I want to contnue discussion here only, but please prioritize the case. My ask, is there any option to connnect in screen sharing mode?

We slowly loosing trust on using TI sensors because of delayed response. This issue been hanging for last one month or beyond. 

We are using below design

https://www.ti.com/lit/ug/swru628/swru628.pdf

Question is, how can se install drivers? The sensor not showing up in COM port. 

Thanks

Karunakar

Hi Karunakar, 

Have you installed the drivers here? https://ftdichip.com/Drivers/vcp-drivers/ 

These are linked in the pdf you shared. Can you please first try installing the VCP drivers from the FTDI website?

Best regards,

Josh

Hi Josh,

We installed the binaries you have shared. With this binaries, we can able to see COM port, but not detecting sensors. 

Can we able to have quick screen sharing meet?

Thanks

Karunakar

Hi Karunakar,

Have you followed the instructions here for bringing up the IWRL6432BOOST EVM?

http://dev.ti.com/tirex/local?id=Getting_Started_With_xWRL6432&packageId=radar_toolbox

This should help you confirm whether the problem is with your board or your computer.

If the COM Port is working, and you flashed your custom PCB with the unmodified motion and presence demo from the SDK (found at C:\ti\MMWAVE_L_SDK_05_05_04_02\examples\mmw_demo\motion_and_presence_detection\prebuilt_binaries\xwrL64xx-evm), then you should see the CLI appear in the terminal at 115200 baud. See settings here for an example.

Please provide screenshots to show that you are using the right settings. If the COM port shows correct here, then you should be able to send a configuration to the device using the industrial visualizer using the instructions here.

Hi Nate,

We are using ES32 as processing unit. Please find attached video having all info. We followed the steps mentioned in the document.

For video, we shown only few seconds, where as we waited for more than a min before closing the putty window

Thanks

Karunakar

Hi,

Are you using your own custom board, or an IWRL6432AOP EVM? If you're not using an EVM, please use one to debug your setup. Can you provide screenshots of the following:

1. A picture of the IWRL6432AOPEVM plugged into your computer with the switch settings visible.

2. A screenshot of the device manager with the IWRL6432AOP EVM plugged in

3. A repeat of the video above with the IWRL6432AOPEVM plugged in, with Teraterm open to 115200 kBaud and pushing the reset button on the IWRL6432AOP EVM. You should see the CLI come up.

Alternatively, if you don't have an IWRL6432AOP EVM, you may also use an IWRL6432BOOST board too. Just start with some validated TI hardware to ensure your setup is right, then we can figure out the differences between the TI hardware and your board.

Best,

Nate

Hi Nate,

We are using our own custom board and we followed below board design for PCB.It does not have any switches.

https://www.ti.com/lit/ug/swru628/swru628.pdf

Is there possibility that we can have screensharing call to avoid delay in arriving the resolution.

Thanks

Karunakar

Hi,

Please follow the instructions above and show that your system is working with the TI EVM. This will help us confirm that your setup is appropriate. Then we can discuss if there are problems with your board design.

Best,

Nate

Hi,

Please understand we are using our own custom PCB board, not TI EVM. My question is, as there's no switches, how can we flush the drivers in this design.

Thanks

Hi Karunakar, 

The video you shared would be the expected behavior if you have not flashed any firmware to the device. Have you flashed any appimage to the device at this point? If not, can you please follow the steps in Section 3 under Flash IWRL6432FSPEVM in the PDF?

Best regards,

Josh

Hi Josh,

We tried that, we dont see anything happening. Is there possibility for having web screen sharing session to show you the issue.

Thanks

Karunakar

Hi Karunakar, 

Can you clarify what you mean when you say you don't see anything happening? Do you mean nothing happens when you try to flash the firmware with the visualizer application? Or flashing appears to be successful but you still get no output afterwards?

If you are unable to flash with the visualizer application, can you please try using the Uniflash tool?

Also, please ensure that you have the device set to the correct mode using the SOP pins. For flashing mode, both SOP0 and SOP1 pins are connected to ground. For functional mode, SOP0 is connected to 3.3V, and SOP1 is connected to ground. Also note, power reset is required after changing the SOP settings.

Please note, we can not accept requests for meetings on this forum but it may be helpful if you could share some pictures of what you are seeing. For example, can you share a screenshot of the visualizer application after you have flashed to confirm the flashing was successful?

Best regards,

Josh

Sure Josh, 

We will try the option and come back. This week, our team not available because of holiday, we will try next week and revert.

Thank you for all your support

Karunakar, 

No problem. Let me know if the issues are still present once you return and check. Enjoy your holiday!

Best regards,

Josh
