Downloading demos to my CYW920719Q40EVB-01 is very inconsistent. It fails a majority of the time. If the UART port is not explicitly set, it cannot find the device. If I set the UART in the target, I get the error:

Download failed. This WICED platform of the SDK only supports download to 207x9B1 devices.
Follow the instructions in the 20719-B1 README.txt for downloading the application.

Hitting reset or doing a recover (-> Sw1 -> Sw2 <- Sw2 <- Sw1) does not fix the problem.
Solved! Go to Solution.

It seems that the board came broken. Uploading projects to other boards works fine. Specifically, the recover function on the original board does not work. It keeps running the prior program after recovery and does not accept new ones.
