Hi, Wpsigma,
The 15W-1CFFPD board support both USBTAB and UART to connect FreeMASTER, only need to change the below settings in SW:
If SCI is used for the debugging console in the MP demo, the settings are as follows:
#define DEBUG_CONSOLE_SUPPORTED (TRUE)
#define FREEMASTER_SUPPORTED (FASLE)
The macros are defined in example-> wct1013PD–>Configure-> appcfg.h.
#define QSCI_CONSOLE_INDEX 0
#define QSCI_FREEMASTER_INDEX 1

The macros are defined in example->wct1013PD->driver->qsci.h.
If JTAG port is used,pls use the following setting:
To use the FreeMASTER and the debug console at the same time, change the FreeMASTER communication interface to JTAG. The settings are as follows:
#define FMSTR_USE_SCI 0 /* To select SCI communication interface */
#define FMSTR_USE_JTAG 1 /* 56F8xxx: use JTAG interface */
The macros are defined in example->wct1013PD–>Configure-> freemaster_cfg.h.
#define FREEMASTER_SUPPORTED (TRUE)
The macro is defined in example->wct1013PD->Configure->appcfg.h.
For detailed information, pls refer to section 2.2.2 Debugging console in WCT101XV10RTDUG.pdf , which can be downloaded from the link:

I suppose that you have the source code, If you want to download code, you have to use USBTAP device and CodeWarrior for MCU ver11.x to download code.
I consulted the AE team for wireless charging, they give the above feedback.
