Hi,

I cannot receive data at the at mmWave Demo Visualizer.

I flashed the sensor with the current xwr68xx_mmw_demo.bin from the 3.3 sdk with the mmwaveicboost evaluation board

When i am trying to connect, it sometimes stuck in "connecting to 2 from 2 targets"

and sometimes it stuck on "waiting for data"

But it never has success to receive data.

I am using Linux, Ubuntu 16.04

What am I am doing wrong?

BTW - i see that when i connect the FTDI_USB cable, the SOP2_FT led is on from some reason. I have tries both with this cable connected and disconnected

Thank you

Hi Efi,

Please check the ES Revision on the silicon. MMWAVE SDK 3.3 works only for ES2.0.

See: http://dev.ti.com/tirex/explore/node?node=ADsPyX6E2a-akoJpFzxp2A__VLyFKFf__LATEST

If you have ES2.0 device, please try sending the chirp config. The data port may show connected when it starts to receive data.

Thanks

Yogesh

Done

In the data port i dont receive anything.

How can i send the chirp data?

Moreover, most of the time, it does not able to connect to the second port.

it writes: " connecting 2 of 2 targets. IWR68xx non-secure ES 02.00"
