WiFi使用方法(WIFI Testing Method)
Test WIFI (EWM-W168)
Connect mini PCIe to PCIe
Connect to SOM-1A10 PCIE2 or 3
The I/F may different with the PCIE slot
I/F:
wlP1p1s0(PCIE2) or wlP2p1s0(PCIE3)
Need to install wpa_supplicant first
Up and ping with I/F wlP1p1s0:
- killall wpa_supplicant
- ifconfig wlP2p1s0 up
- wpa_passphrase "Pilimao" "0913079939" > /tmp/wpa.conf
# wpa_supplicant -BDwext -i wlP2p1s0 -c /tmp/wpa.conf
Request IP Addr:
- dhclient -d wlP2p1s0
- ping 8.8.8.8:
Add nameserver:

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.
- 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.
- ./watchdog-test-adv -t 10 -p 13
RTC test
Disable RTC sync service:
- systemctl stop systemd-timesyncd
Set system time to current, then write to RTC:
- date 110415302022 && hwclock -w && date
Set one incorrect time, then read time from RTC to verify:
- date 010100002000 && hwclock -r && date
Set the system time from the RTC:
- 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
- Note: Make sure the content of SPI nor flash is erased
- echo -n $'\x06\x05\x04\x03\x02\x01' > test
- dd if=test of=/dev/mtdblock0
- hexdump -C /dev/mtdblock0 -n 64
通用方法(General Method)
查看CPU温度(Check CPU Temperature)
查看CPU频率(Check CPU Frequency)
cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq >> 900000 cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq >> 1200000
查看内存容量(Check Memory Capacity)
busybox free -m
查看存储容量(Check Storage Capacity)
busybox df -h
