How should I set the config of minicom to get the correct message from NUCLEO-F746ZG?

I have searched lots of articles, and followed their approach, but minicom still show garbled. (I tried teraterm on windows before. Its message is correct.)

The following is my command lines:

---------------------------------------------------------

$ sudo minicom -s

Serial port setup >

  | A -  Serial Device   : /dev/sdc

  | B - Lockfile Location   : /var/lock

  | C -  Callin Program   :

  | D - Callout Program   :

  | E -  Bps/Par/Bits    : 115200 8N1

  | F - Hardware Flow Control : No

  | G - Software Flow Control : No 

---------------------------------------------------------

I'm pretty sure the config is equal to my USART3 setting:

---------------------------------------------------------

/* USER CODE END USART3_Init 1 */

 huart3.Instance = USART3;

 huart3.Init.BaudRate = 115200;

 huart3.Init.WordLength = UART_WORDLENGTH_8B;

 huart3.Init.StopBits = UART_STOPBITS_1;

---------------------------------------------------------

Is there any step I lost?

/dev/sdc is a hard disk or some other mass storage device. You are actually seeing its boot sector in the terminal. Try with a serial port instead.

I changed "/dev/sdc" to "/dev/ttyACM0", and it showed the correct message. Thanks.
