io_cfg.useUart = CyTrue;
io_cfg.useI2C = CyFalse;
io_cfg.useI2S = CyFalse;
io_cfg.useSpi = CyFalse;
io_cfg.isDQ32Bit = CyTrue;
io_cfg.lppMode = CY_U3P_IO_MATRIX_LPP_DEFAULT;
/* No GPIOs are enabled. */
io_cfg.gpioSimpleEn[0] = 0;
io_cfg.gpioSimpleEn[1] = 0;
io_cfg.gpioComplexEn[0] = 0;
io_cfg.gpioComplexEn[1] = 0;

Hi,
Initialization looks fine.
Please let me know the hardware board that you are using.
Are you using FX3 DVK?
Are you probing the lines GPIO[46] to 49.
Thanks,
sai krishna.
