串口使用方法(Serial Port Operating Method)

RS-232 test: Connect RS-232 loopback

COM2: /dev/ttyS1

Test script:

<span lang="EN-US" style="color:black">#!/bin/bash</span>

<span lang="EN-US" style="color:black">#set -x #echo on</span>


<span lang="EN-US" style="color:black">echo "Enable and Set RS-232 $1..."</span>

<span lang="EN-US" style="color:black">stty -F $1 speed 115200 -onlcr -echo</span>

<span lang="EN-US" style="color:black">sleep 1</span>


<span lang="EN-US" style="color:black">echo "Check RS-232 $1... speed"</span>

<span lang="EN-US" style="color:black">sleep 1</span>


<span lang="EN-US" style="color:black">echo "echo Test_RS-232 to $1 x5..."</span>

<span lang="EN-US" style="color:black">sleep 1</span>


<span lang="EN-US" style="color:black">cat $1 &</span>

<span lang="EN-US" style="color:black">sleep 1</span>

RS-232: ttyS1(COM2 loopback test):

# ./RS-232_test.sh /dev/ttyS1

Watch Dog Function

System will reboot after enable watchdog and count 60 sec :

Check default watchdog time:

Enable watchdog, system will reboot after 60 sec.

1. echo 1 > /dev/watchdog

System poweroff after 60 sec. cannot reboot again

 Set timeout to 10 and pin rate to 13, the system will reboot after 10 seconds.

1. ./watchdog-test-adv -t 10 -p 13

RTC test

Disable RTC sync service:

1. systemctl stop systemd-timesyncd

Set system time to current, then write to RTC:

1. date 110415302022 && hwclock -w && date

Set one incorrect time, then read time from RTC to verify:

1. date 010100002000 && hwclock -r && date

Set the system time from the RTC:

1. hwclock -s && date

Storage Function Test :

SATA DISK:

  Read/write data and compare sha512 result

SPI Read/Write test

Write/Read/Verify data in the start/end 4 byte of flash

1. Note: Make sure the content of SPI nor flash is erased

1. echo -n $'\x06\x05\x04\x03\x02\x01' > test

1. dd if=test of=/dev/mtdblock0

1. hexdump -C /dev/mtdblock0 -n 64
