I just want to program my new CYW920819 eval board (20819 silicon) with the Modus Toolbox 2.0. I tried this with the J-Link Plus Version 10.1 without success.
Project explorer
Debug configuration
Error
Console output

Checking target voltage...
Target voltage: 3.28 V
Listening on TCP/IP port 2331
Connecting to target...ERROR: Could not connect to target.
Target connection failed. GDBServer will be closed...Restoring target state and closing J-Link connection...
Shutting down...
So it seems, that there can't be established a connection with the Board and my J-Link. I already tried to switch off SW 9 and to remove all four jumpers for the PUART connection interface. Is there anythink elese I could do?
Best Regards!

Hi ,
You can't program CYW20819 using JTAG / SWD. It can be programmed only via HCI UART .
Please note Jlink can be used only for debugging.
You may refer to the doc available here for the steps:

Hi, thanks for your reply!
Ok, but how to programm a device via HCI UART? In the documentation Getting Started with CYW20819 it says to build and program the device via Modus Toolbox.
But I don't have this features in my Modus Toolbox 2.0.
What can I do?
Best Regards!

Okay, question is obsolete! I did it!
I had to switch to the example project (Motion_Sensor) and not to the base project (wiced_btsdk). There you can see Launches described in the docuementation. After that I had to do the HCI Reset procedure and it worked!
Best Regards!

Dear Cypress! Your software and hardware features are in most cases very fancy! But please update your documentation and your documentation management. It is very hard to find the right ressources / datasheets... A more structured documentation would be great in the future! Best Regards!
