uart example for nRF6700 (nRFgo starter kit) didn't work

Question

I installed nrfgostudio_win-64_1.15.1_installer, nrfgo_sdk_2.3.0_setup and nrfprobe_v2_0_0_7252 to test nRFgo starter kit(nRF6700). I tried to test uart on nRF24LE1D. but the uart example didn't work. I don't see "Hello World!" from P0.5(TXD). 
 Did I miss something? How to do fix this bug? 
 thank you.

Thanks,
I found problem, I use 24-pin package, so there is no P0.7 or P1. I had to use just "P0DIR = 0x5F;" 
 void main(void)
{
// Configure TXD pin as output.
// P0.5, P0.3 and P1.0 are configured as outputs to make the example run on
// either 24-pin, 32-pin or 48-pin nRF24LE1 variants.
P0DIR = 0x5F; <== don't use P0.7 as input
//P1DIR = 0xFE; <== commented out 
 // Initializes the UART
hal_uart_init(UART_BAUD_9K6); 
 // Wait for XOSC to start to ensure proper UART baudrate
while(hal_clk_get_16m_source() != HAL_CLK_XOSC16M)
{} 
 // Enable global interrupts
EA = 1; 
 // Print "Hello World" at start-up
putstring("
Hello World!
"); 
 for(;;)
{
// If any characters received
if( hal_uart_chars_available() )
{
//P3 = 0x11; <== commented out
// Echo received characters
putchar(getchar());
}
}
}

for(;;) { // If any characters received if( hal_uart_chars_available() ) { P3 = 0x11; // Echo received characters putchar(getchar()); } } }
