LPC812 UART in Polling mode does not works

Hi Everyone,

 

Im using LPC812 MAX board,

Initially i have configured the board for two UARTs (UART0 as Debug port and UART1 as external) and it works.

later i m in need of switching the external UART into polling mode (refer to lpcOpen_3_01-> periph_uart_rom_polling)

after that Debug UART stopped working. my suspect is  "Init_UART_PinMux" something going wrong here.

i have attached the polling example , please help me asap.

 

any other good suggestion to communicate with esp8266 without polling ?

 

Thanks,

Ashok r
