UART with PAN1740

Hi,

I have a PAN1740 board. I would like to have a serial communication. I have read some answers from previous posts and I have followed all the steps to enable the UART .

However no success. I only see some gibberish on teraterm.

Here I am using ble_security project.

The steps I followed are:

1.#define CFG_PRINTF

2.在GPIO eservations功能:

#ifdef CFG_PRINTF_UART2

RESERVE_GPIO( UART2_TX, GPIO_PORT_0, GPIO_PIN_4, PID_UART2_TX);
RESERVE_GPIO( UART2_RX, GPIO_PORT_0, GPIO_PIN_5, PID_UART2_RX);
#endif

3. in set_pad_functions

#ifdef CFG_PRINTF_UART2
GPIO_ConfigurePin(GPIO_PORT_0, GPIO_PIN_4, OUTPUT, PID_UART2_TX, false);
GPIO_ConfigurePin(GPIO_PORT_0, GPIO_PIN_5, INPUT, PID_UART2_RX, false);

#endif

4. I have invokes the the arch_printf(). in user_security.c file

void user_app_connection(uint8_t connection_idx, struct gapc_connection_req_ind const *param)
{
if (app_env[connection_idx].conidx != GAP_INVALID_CONIDX)
{
arch_printf(" \r\n connected");

5. I have added app_console folder to the project and also added the path in the Options for target -> C/C++ tab .

Then I build the project and the on and off the debugger. I see some gibberisch data no serial data.

I have selected the 115200 baud rate also 8 bit data, no parity, no flow control and stop bits 1. I am not able to understand the problem.

Additionally I have also added:

6. in the periph_init function

SetBits16(CLK_PER_REG, UART2_ENABLE, 1); // enable clock for UART 1

SetWord16(UART_LCR_REG, 0x80); // set bit to access DLH and DLL register

// divisor = 1000000 / 115200 = 9

SetWord16(UART_IER_DLH_REG,(9&0xFF>>8));//set high byte

SetWord16(UART_RBR_THR_DLL_REG,9&0xFF);//set low byte

SetWord16(UART_LCR_REG,3); // no parity, 1 stop bit 8 data length and clear bit 8

SetBits16(UART_MCR_REG, UART_SIRE, 0); // mode 0 for normal , 1 for IRDA

SetWord16(UART_IIR_FCR_REG,1); // enable fifo

SetBits16(UART_IER_DLH_REG,ERBFI_dlh0,0); // IER access, disable interrupt for available data

still no change in the serial data.

Kindly suggest me the issue. Thank you.
