Hi daba_4649501 ,

Yes , seems to be like some issue with board. Please try with a new one. Hope you are able to do download FW to your CYW20820 Eval board without any problem. 

Also please note, the latest 20719 version is 20719B2  . For new customer application, we recommend to use 20719B2.


Meanwhile I would suggest you to go through our WICED Academy files for getting started : GitHub - cypresssemiconductorco/CypressAcademy_WBT101_Files: Files for WICED Bluetooth 101 class
