i am trying to use UART1 for debugging.

This is what i have done so far:

- Connected FTDI RX pin to ESP8266 GPIO2
- user_init():
uart_init(BIT_RATE_115200, BIT_RATE_115200);
os_install_putc1((void *)uart1_write_char);
PIN_FUNC_SELECT(PERIPHS_IO_MUX_GPIO2, FUNC_U1TXD_BK);
os_printf("Hello");

I did point uart1_write_char to the same function in your uart.c file.
Is this correct? Or should i implement it by myself?

My problem is that there is no data at all received by my terminal program in Ubuntu.

What am i doing wrong?

Best regards,
potter68
