Dear
I try to connect more than 2 sata disk on BananaPI R2 to do a NAS
I has thinking a miniPCIe with a controler Marvel 88SE9215 it supported ; messages on Espressobin let know it is supported
but when i try to plug ar HDD on, nothing append
it do test with Armbian_5.75_Bananapir2_Debian_stretch_default_4.19.20.img -
I don't understand the mounting/mapping/bridging of ethernet ports on Banana Pi R2 : eth0, br0, wan, lan1-2-3-4
br0 is the bridge but in eth0, br0, wan, lan1-2-3-4 what is physical interface or logical interface ? -

We used to have both, but maintaining both become too much when there is little help ... I would like to see both + some basic firewall config, but don't know when
https://github.com/armbian/config/blob/master/debian-config-jobs#L513I think with my firewall script it is possible to do different set of rules ( Bridge, Routing, NAT ) can be enable according to desired mode
-
Here a small set of rules i use with the precedent script
Rule can be easy enable and disable with set or reset executable status off file rule
-
I done some thing no bad on my 2 hotspot in routing mode with a script to manage IPTABLES rules
The script firewall_rules.sh in /etc/init.d/ load pre-defined rules in /etc/firewall.d/
-
I usually keep the bridge mode for wifi spots with network connections must remain open during roanning
The NAT mode is much easier to set up and the main limitation is that you can't open a network connection from network to the wifi
I prefer the routing mode but and it's more complicated to set up -
For your interface naming there are new rules : https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/networking_guide/ch-consistent_network_device_naming
Generally this new naming come with re-install and not update
-
For hotspots, there are 3 modes :
Bridge : Wifi IP address are in same range as your network and it's your DHCP deliver wifi IP address
Routing : Wifi IP address are not in the same range as your network, wifi IP address are deliver per the hotspot ; your network must be "informed" the range IP of wifi ( routing table )
NAT : The wifi is full managed per the hotspot ; on your network you see only connection initiated per the hotspot
Each mode have advantages and inconvenient, that depending your wifi using -
Buy a new SD card and reinstall it with Armbian (the current version/origin or the new update)
Restart your O-droid with the new SD card and do the basic config (name, network)
With a SD/USB card reader, connect the old card to your O-dorid
Retrieves what is still readable and makes the copies directly where is needed on the new SD card -
I done some test with a bananapi M1 with Armbian_5.91_Bananapipro_Debian_stretch_next_4.19.59
In this case, the display working

In case, both IP address are static, write your your DNS sever in /etc/resolv.conf : nameserver 'dns_IP_address'
If one IP address from DHCP, network-manager will re-write resolv.conf with data from DHCP
If the DNS from DHCP is not good, you must fix a static address one each interface and write manually resolv.conf
What is this ?????? internet access blocking port 80 and 443
Are you sur port 8000 or 8001 are open ; for user, prefer port 8080, some internet browser block no standard port ( i have had this problem with port 8000 and must move to 8080 )For the firewall, normally all Armbian have installed IPTABLES ( it's the native linux firewall ) but it's only on command line
I never used webmin but i think it said "not installed" because there are not filtering rules
-
Your address 192.168.1.2 is it delivry by DHCP or it's a static address ?
The file /etc/resolv.conf is rewrite per NetworkManager when you receive your address from DHCP
To separate administrative web tools (lan) and user/client web tools (wan)
do with Apache two virtual host
The first : user/client web tools (wan) on port 80 and 443
The second : administrative web tools (lan) on port 8080With the firewall (iptable or iptable gui ) open on wan only port 80 and 443

I do some tests on a new display from WaveShare : 5.5inch HDMI AMOLED, 1080x1920
https://www.waveshare.com/product/modules/oleds-lcds/oled/5.5inch-hdmi-amoled.htm
On the wiki, it's wrote : To use it on RaspberryPi, you must change the config.txt file for to ajuste hdmi parameters :
https://www.waveshare.com/wiki/5.5inch_HDMI_AMOLEDmax_framebuffer_height=1920
max_usb_current=1
config_hdmi_boost=10
hdmi_group=2
hdmi_force_hotplug=1
hdmi_mode=87
hdmi_timings=1080 1 26 4 50 1920 1 8 2 6 0 0 0 60 0 135580000 3
I do it and that working fine
I add this to ajust resolutionmax_framebuffer_width=1080
max_framebuffer_height=1920framebuffer_width=600
framebuffer_height=1080But all that is on RasberryPI and i would like use it on BananaPI M1 on M2 zero
I tried to write it in armbianEnv.txt but the resolution of display haven't changed
How i can do that on BananaPi ?

Hi
That is a display with a very good quality of image
I haven't test it with a pen buy the reaction is very good with the finger ( test it on Xfce with police DPI at 150 )
For the power you must plug one USB for the touch screen and if your board can supply the standard 0.5A of USB, it's OK and work with just one USB
In my case, i would like to doing the crazy idea : doing a phone
In my test, the power needed is :
0.4A for the board ( RaspberryPi 3B+ ) + 0.4A for the screen => 0.8A on a battery is hard survive longtime
That can be better with a RaspberryPi Zero but there are no Wifi and Bluetooth
I would like use a BananaPI, maybe a BananaPi Zero
I don't known what happen during my test but actually the screen don't display any image
