Hi. I use lpc1769 chip with custom board with sending hex code via FTDI.  I watch tutorial video for lpcopen, I use  MCUxpresso and import " periph_uart_rb"  "lpc_board_nxp_lpcxpresso_1769" "lpc_chip_175x_6x" projects.  due to using UART0, ı change these

 

#elif defined(BOARD_NXP_LPCXPRESSO_1769)
#define UART_SELECTION LPC_UART3
#define IRQ_SELECTION UART3_IRQn
#define HANDLER_NAME UART3_IRQHandler
#else
#error No UART selected for undefined board
#endif

 

UART3 to UART0

 

#elif defined(BOARD_NXP_LPCXPRESSO_1769)
#define UART_SELECTION LPC_UART0
#define IRQ_SELECTION UART0_IRQn
#define HANDLER_NAME UART0 IRQHandler
#else
#error No UART selected for undefined board
#endif

 

 

But these are not working . No data is being send via ftdi to usb 

 

Do I need any setting for custom board ?

How can ı run this examples ?
