NanoPi Duo2 IoT-Box not working?

Moderators: chensy, FATechsupport

Hello,

I want to use my NanoPi Duo2 with the NanoPi Duo2 IoT-Box, but nothing on the board works...
Power on...
Power LED (red): on
LAN LEDs flicker only for a short periode and then off

On the console:
>> sudo ifconfig eth0 down
>> sudo ifconfig eth0 up
Shows no error (0)

Short:
No USB
No LAN (No DHCP requests)
No GSM

Has anybody the same problem?
Is the IoT-2G Application Carrier Board wreck?

Regards
which port (UART/WiFI/Ethernet?) do you use for the console?

Did you insert the Duo2 the right way to the box-board?

Do you power the box board via MicroUSB-Port? (is the Duo2 powered from the box-board?)
Did you switch on the box-board?

Hello,

which port (UART/WiFI/Ethernet?) do you use for the console?
- UART and WiFi works as expected

Did you insert the Duo2 the right way to the box-board?
- YES

Do you power the box board via MicroUSB-Port?
- Yes, 2A

(is the Duo2 powered from the box-board?)
- Yes

Did you switch on the box-board?
- No (I've only one here)

Thanks 4 reply
did you try "sudo ifconfig -a" if there is any eth0-device?

you can also check the output of "dmesg" if there are any errors about LAN/GSM.

Did you check within "npi-config" if there is any hardware disabled which can be enabled?

If eth0 could found with "ifconfig -a" then maybe its nit configured for DHCP?
Then you could try to configure it with "nmtui" if the Network-Manager is installed.

Yes. With AND without carrier-board

I can only configure the WiFi-Device. eth0 not showing up.

you can also check the output of "dmesg" if there are any errors about LAN/GSM.

#> dmesg

I see only 1 red error line:

and (not red)

I also got no eth0 in /dev on another SBC, but eth0 is working.

You could try to expand eth0 in /etc/network/interfaces:

auto eth0
allow-hotplug eth0
no-auto-down eth0
iface eth0 inet dhcp

how about:
dmesg|grep -i eth0

or if the ethernet-module/driver has been loaded:
lsmod

Entries added + Reboot = Same as before :/

how about:
dmesg|grep -i eth0

#> dmesg | grep -i eth0

"No MAC Management Counters available" sounds not really good

#> modprobe dwmac-sun8i

0 (Seems to be ok)

And there is no /dev/ttyUSB?, ttyAMA? or ttyS?, so no GSM/GPRS...
Will I've to execute modprobe usbserial vendor=??? product=??? or something else to get the SIM800C Module up?
GSM can be connect at /dev/ttyS3
u can refer it in the sim800c-test.py file
PIN 11 for turning the power on
(if using wiringNP gpio command, try gpio mode 16 out)
after that you will see the blinking light for the GSM and u can use minicom to connect
http://wiki.friendlyarm.com/wiki/index.php/GSM/GPRS
By default the FriendlyCore system FriendlyElec provides has a Python demo for testing SIM800C.

I searched for *sim800c* and... nothing found. And I haven't found any download link for the test python scripts or lib...

GSM can be connect at /dev/ttyS3
u can refer it in the sim800c-test.py file

#> gpio mode 16 out

0
(OK: GPIOG11 | OUT)

#> ls /dev/ttyS*
/dev/ttyS0 /dev/ttyS1 /dev/ttyS2 /dev/ttyS3 /dev/ttyS4 /dev/ttyS5 /dev/ttyS6 /dev/ttyS7
(Seems to be OK)

But the light for the GSM-module is still off.
to turn on the gsm, u need to install wiringNP
then use the following:
sudo gpio mode 16 out
sudo gpio write 16 1

for the sim800c-test.py file, u have to use the official image, and the instruction is in official wiki
http://wiki.friendlyarm.com/wiki/index. ... o2_IoT-Box

path is /root/Python/GSM-GPRS/sim800c

the sim800c-test script also turns on the gsm for u
to turn on the gsm, u need to install wiringNP
then use the following:
sudo gpio mode 16 out
sudo gpio write 16 1

I'm allready installed wiringNP
#> sudo su -
#> gpio mode 16 out
#> gpio write 16 1
Same as before. Commands accepted (no error=0) but GSM and light are dead.

I have allready installed the official Image (http://wiki.friendlyarm.com/wiki/index. ... mage_Files)
"nanopi-duo2_sd_friendlycore-xenial_4.14_armhf_20181218.img"
and there is no Python directory under /root
use sudo su before checking the directory
As you can see... I'm root and there is no such directory:
pi@NanoPi-Duo2:~$ sudo su -

4 others: Don't use nanopi-duo2_sd_friendlycore-xenial_4.14_armhf_20181218.img Python scripts are missing.
