IWR6843ISK: I got IWR6943ISK+DCA1000EVM (without MMWAVEICBOOST), when load BSS FW in mmwave studio, it showed "Download FW failed with error -1"

Hello,

Please check this document for the steps on running the IWR6843 + DCA1000 correctly. Also what revision of ISK do you have? On the corner of the EVM is will say Rev. followed by a letter. Only the newest revision of ISK can work with a DCA1000 without a mmWaveICBOOST.

REV D. When the PC links IWR6843ISK, there are no driver alerts. 

Hello,

Since you have a REV D, you are able to get raw data without a DCA1000. Do you have Code composer v7.1 or XDS Emulation Software Package v6.0.579.0+? If not then that can be why there are no driver alerts.

You can download the driver here:

Thanks. I have installed XDS Emulation Software Package 9.2.0.00002 and ccs_setup_12.0.0.00009, XDS110 still is no any alerts in device manager. 

Hello,

So just to confirm, when you plug your ISK in with it being in flashing mode, by no driver alerts you mean you do not see any new COM ports show up in Device Manager? Do you have the ability to try a different USB cable, and do any LEDs turn on when you connect the ISK? Even if the ISK is in the wrong mode when connecting to a computer, you should still see the COM ports and some LEDs turn on.

Thanks. IWR6843ISK Rev D needs to install driver in www.silabs.com/.../usb-to-uart-bridge-vcp-drivers. The Silicon Labs Dual CP210X has been installed successfully. But now, the COMs named AR-Devpack-EVM-012 are missed in device manager. 

Thanks. The cable is for charging, not communication.  Once the data cable is replaced, it will work normally.
