Thanks for info - i tried using this function and modifying uart_init as you mentioned in the post - but still sf is not ok at all:

Code: Select all

void user_init(void)
{
   uart_init(BIT_RATE_115200,BIT_RATE_115200);
   os_printf("SDK version:%s\n", system_get_sdk_version());

   os_printf("Module Test\nChip_id: %lu\n", system_get_chip_id());
   wifi_set_opmode(STATIONAP_MODE);//STA + AP (page 25)
//(...)

}

Both os_printf are sent using default BaudRate 74880.
Then messages about opmode is sent using 115200.

Hi,

For me too the problem same. I cannot edit the badrate by driver included in nonos as well as rtos sdk.

I fixed this issue by adding a 1 ms delay after initializing UART:

Code: Select all

uart_init(115200, 115200);
os_delay_us(1000);
