Customer feedback:
I followed the instructions from the links you forwarded. I have the IAR downloaded and opened the ZNP project into it. Then followed the steps below
Now, if USB CDC interface directly from the CC3538EM is desired instead then simply add HAL_UART_USB to the pre-defined options, include the following directories (C/C++ Compiler -> Preprocessor):
$PROJ_DIR$\..\..\..\..\..\Components\usblib\cc2538\source\library
$PROJ_DIR$\..\..\..\..\..\Components\usblib\cc2538\source\library\cc2538
$PROJ_DIR$\..\..\..\..\..\Components\usblib\cc2538\source\class_cdc
And the following libraries (Linker -> Library):
$PROJ_DIR$\..\..\..\..\..\Components\usblib\cc2538\bin\iar\usblib.lib
$PROJ_DIR$\..\..\..\..\..\Components\usblib\cc2538\bin\iar\usbcdc.lib
and rebuild the project to get .out file, then flashed this file using the flash programmer 2.
Even after this I couldn’t see the cc2538EM when directly connected to USB.
Let me know if this is the right approach.
