Hello everyone,

I just stated working with the CYW92076WCDEVAL evaluation kit and I'm following the "CYW920706WCDEVAL Kit Guide" in order to get the "hello sensor" demo working, but when I start the download ( demo.hello_sensor-CYW920706WCDEVAL download ) I get this message:

Detecting device...

********* Detection Failure *************

+------------------------------------------------------------------------------------------+

| The CYW20706 was not detected. Verify that the device is connected, power-cycle if       |

Even though I'm able to detect both /dev/ttyWICED_HCI_UART0 and /dev/ttyWICED_PUART1.

All the dip switches and jumpers are in their correct positions too.

I've tried the make command "demo.hello_sensor-CYW920706WCDEVAL download UART=/dev/ttyWICED_HCI_UART0" with no success. That throws:

Downloading application...

Download failed. This WICED platform of the SDK only supports download to 20706A2 device.

So I tried to recover the board (steps described in Appendix D), but that doesn't work either.

I know the board works because when I open a terminal on port /dev/ttyWICED_PUART1 I'm able to see the "hello sensor" traces (the board is shipped preloaded with that sample application).

For more information, this is my setup:

Ubuntu 14.04.2 LTS x86_64

WICED Studio 6.0

Thank you in advance

There is an additional step while working in an Linux environment. Did you perform the step described in Appendix C in the above mentioned Kit Guide?

Yes, I did that too. It's still not working though.

Any idea?

Have you made sure that HCI UART port is not opened in any terminals ?
