IWR1443: AR1xxx DevPack USB driver enumeration

Gunter Schmer

Part Number: IWR1443

Hi,

I am trying to get the Raw Data Capture to work with the IWR1443/DevPack/TSW1400 according to the instructions at

The problem I am running into has to do with the enumeration of the DevPack and its 4 virtual USB ports. When connecting the USB to the devpack and installing the FTDI drivers at

C:\ti\mmwave_dfp_00_07_00_04\rf_eval\ftdi

the Windows PC (WIN7 or WIN10 PCs tested) enumerates with

"USB Serial Port (COMx)" rather than "AR-DevPack-EVM-012 (COMx)"

Looking at the ftdiport.inf file in the above location we can see this:

[Strings]
FTDI="FTDI"
DESC="CDM Driver Package - VCP Driver"
DriversDisk="FTDI USB Drivers Disk"
PortsClassName = "Ports (COM & LPT)"
VID_0403&PID_6001.DeviceDesc="USB Serial Port"
VID_0403&PID_6010.DeviceDesc="USB Serial Port"
VID_0403&PID_6011.DeviceDesc="USB Serial Port"
VID_0403&PID_6014.DeviceDesc="USB Serial Port"
VID_0403&PID_6015.DeviceDesc="USB Serial Port"
VID_0451&PID_FD01.DeviceDesc="AR12-MB-EVM-1_FD01"
VID_0451&PID_FD02.DeviceDesc="AR12-MB-EVM-1_FD02"
VID_0451&PID_FD03.DeviceDesc="AR-DevPack-EVM-012"
SvcDesc="USB Serial Port Driver"
SerEnum.SvcDesc="Serenum Filter Driver"

In order for the RadarStudio to work we need the AR-DevPack-EVM-012 (COMx) enumeration. How can this be accomplished? Does it have to do with the DevPack itself and maybe the FTDI firmware that is in the Devpack?

It feels like we should be enumerating with VID 0451 in order to get to the other Device Descriptor ...

Thanks,

Hi Gunter,

Just to clarify what we tried on debug call.
After the devpack was connected and update port driver from DFP was tried the DEVPACK ports continued to show as USB Serial Port, that is the driver from DFP did not seem to take effect on your machine.

As an alternative we discussed if you could try it on the different machine to determine if it was a machine dependent issue.
Wonder if you had a chance to try it on a different machine?

Thank you,
Vaibhav

Hello Gunter,
Once you install the driver and it shows up as USB Serial ports can you again right click and update the driver in a similar manner? For each port it needs to be done twice.

Vivek

Hi Vivek,

I tried several times the "Update Driver", but it never changes away from the "USB Serial Port" name, when it enumerates.

Hello Gunter,
Did the com port issue with the Dev Pack get resolved?

Hi Vivek,

yes it did. I had a faulty DevPack with corrupted EEPROM. It was not recoverable even with FTDI firmware programming. A new DevPack solved the issue of correct enumeration.
