I follow Adding Communication Device Class Interface to FX3 Firmware - KBA229099. and added all the codes into cyfxslfifousbdscr.c and cyfxslfifosync.c. When i try it out at my host-PC, windows 10 device manager can detect the cypress bootloader but the USB-Serial-device did not show up in device-manager-other device.
i am using the example from SlaveFifoSync.rar in https://community.infineon.com/t5/Knowledge-Base-Articles/Adding-Communication-Device-Class-Interfac...
do i need to add the codebelow from https://community.infineon.com/t5/Resource-Library/SlaveFiFoSync-example-with-a-CDC-debug-console/ta..., into cyfxslfifosync.c
void SwitchConsoles(void)
{
CyU3PReturnStatus_t Status;
// Only proceed if USB connection is up
if (glIsApplicationActive)
{
// Tear down DMA channels that need to be reassigned
CyU3PDmaChannelDestroy(&CDCtoCPU_Handle);
// Switch console
UsingUARTConsole = !UsingUARTConsole;
CyU3PDebugPrint(4, "Switching console to %s", UsingUARTConsole ? "UART" : "USB");
CyU3PThreadSleep(100); // Delay to allow message to get to the user
// Disconnect the current console
CyU3PDebugDeInit();
CyU3PThreadSleep(100); // Delay to allow Debug thread to complete and all buffers returned
// Connect up the new Console out - this is simpler than the I2C case since the USB socket is an infinite sink
Status = CyU3PDebugInit(UsingUARTConsole ? CY_U3P_LPP_SOCKET_UART_CONS : CY_FX_EP_CONSUMER_CDC_SOCKET, 8);
CheckStatus("DebugInit", Status);
CyU3PDebugPreamble(CyFalse); // Skip preamble, debug info is targeted for a person
// Say hello on the new console
CyU3PDebugPrint(4, "Console is now %s", UsingUARTConsole ? "UART" : "USB" );
// Now connect up Console In
Status = InitializeDebugConsoleIn(UsingUARTConsole);
CheckStatus("InitializeDebugConsoleIn", Status);
// Connect CDC_Loopback if necessary
}
else CyU3PDebugPrint(4, "USB not active, cannot switch consoles\n");
}
CyU3PReturnStatus_t InitializeDebugConsoleIn(CyBool_t UsingUART)
{
CyU3PDebugPrint(4, "\nSetting up USB_CDC Console In");
CyU3PMemSet((uint8_t *)&dmaConfig, 0, sizeof(dmaConfig));
dmaConfig.size = EpSize[CyU3PUsbGetSpeed()];
dmaConfig.count = 2;
dmaConfig.prodSckId = CY_FX_EP_PRODUCER_CDC_SOCKET;
dmaConfig.consSckId = CY_U3P_CPU_SOCKET_CONS;
dmaConfig.dmaMode = CY_U3P_DMA_MODE_BYTE;
dmaConfig.notification = CY_U3P_DMA_CB_PROD_EVENT;
dmaConfig.cb = CDC_CharsReceived;
Status = CyU3PDmaChannelCreate(&CDCtoCPU_Handle, CY_U3P_DMA_TYPE_MANUAL_IN, &dmaConfig);
CheckStatus("CreateCDC_ConsoleInDmaChannel", Status);

else
{
Status = CyU3PDmaChannelSetXfer(&CDCtoCPU_Handle, 0);
CheckStatus("ConsoleInEnabled", Status);
}
}
return Status;
}
