Hi: I use orange pi pc to build a little chromium kiosk for showing some static information(like temperature). most things are fine. but there is a electronic scroll bar which is not running smooth. I check my current environment (armbian 22.08 with ubuntu 22.04) that I am running xorg with fbdev driver. I wonder if there is other things I can try for the hardware? I search the forum and I found there is "lima" driver, but I don't know if I am using it or not. I can see "lima" is loaded via "lsmod" but am I using it currently? I hope the orange pi pc can do better with newer driver. if not, what's the next armbian pi I should buy to get better chromium experience? thanks a lot for help!!

thanks a lot for the information!

Hi: I am using armbian build on Debian 10(buster). I wonder how long I can get update if I don't upgrade to Debian 11(bulleye). I am satisfied with the current OS. if possible I want to continue use buster until Debian 12 comes out, but I don't know how long will armbian support old debian releases. thanks a lot for the hint!

thanks a lot for the hint. my usage is headless too. no wifi no network-manager but maybe with usb sometimes. your blacklist would be great help.

Hi: I am new to Armbian Buster. I understand the legacy h3consumption is gone now. I wonder if I can do something similar under Armbian Buster like: 1. only allow 1 or 2 core 2. lower ram frequency 3. disable hdmi

Hi Werner & Igor: thanks a lot for the advice. now I understand Armbian buster will be my best choice. thanks again for your kindly help!!

Hi: I am using debian jessie on orange pi H3 boards and I am very satisfied with it. but I need to upgrade now since jessie is out of support. i want to upgrade to debian buster since my pi is using as a server without any display attached. but I wonder maybe there is something good I missed from ubuntu: like 10 years LTS support? or perhaps most developers are using ubuntu so it is more mature? just need some advice. thanks a lot!

yes debian jessie is still there. but the armbian jessie packages are gone. like "linux-image-sun8i_5.75_armhf.deb". I got some of them. I just hope I have last chance to sync these great packages.

hi: I have old allwinner H2/H3 boards which work very stable with armbian jessie. although I can still get debian jessie packages, I found armbian jessie packages are gone from apt.armbian.com. is there any place I can sync these armbian jessie packages? thanks a lot for your help!!

how about the temperature of the new orange pi zero LTS? orange pi zero ver 1.0 is cool. ver 1.4 and ver 1.5 are hot.

Hi: thanks a lot for your hint!! google "armbianEnv.txt" I learn a lot of things. BTW, I can use "extraargs" to add boot parameters now. thanks again for your kindly help.

Hi: sorry for asking it again. anybody know how to add boot parameter to legacy armbian 3.4? do I need to re-compile something to do the work? thanks a lot for help!!

Hi: I want to add "nowayout" watch dog parameter to my orange pi pc. I think the syntax should be "sunxi_wdt.nowayout=1". but I don't know how to add this to kernel boot parameter in armbian? is there a config file to add boot parameter? BTW I found if I shut down my orange pi PC normally, I can not restart it unless I unplug/plug the power cord. is this behavior expected? thanks a lot for help!!

Hi: sorry I don't have name. there are tones of converters in the market and they basically looks like the same. the new and old one both use SP3232EEN.

Hi: thanks for the hint. it is easier to do the test. today I got new converters and they are fine. I don't know what happened to my original converter. I saw some people said there are many fake chips which can only do 9600 bps. but since the new converter works fine, I don't want to bother what happened to my old converter. thanks for all the help!! now I can minicom my routers!

hi: I have tried to use UART1 to connect UART0 directly, and I can get login screen. so I think UART1 configuration is fine, at least TTL to TTL.

Hi: there is some difference in hardware. when I minicom from PC to SBC, the SBC is using UART0. when I minicom from SBC to router, the SBC is using UART1. I have test the router and it only need RX/TX/GND to work, no need for CTS/RTS/DTR/DSR. after more searching, I found maybe my converter is not good enough. so I ordered more converters to see if there is any difference. it will take two days to arrive so I can continue the experiment. thanks a lot for all the help! I will report the results later.

Hi: I tried 3.3V and 5V VCC. and I use wires to connect the pins one-by-one, so I can switch tx/rx at each side easily. since I can use the converter from RS323 to TTL, I think it is working. it just can not convert from TTL to RS232. after observation, I think one side of the converter is "tx,rx,gnd,vcc"(TTL) and the other side is "tx,rx,gnd"(RS232). maybe I should try more converters for testing. could anyone test his converter if control the router/switch via SBC works?

hi: thanks for the hint. I will try to build a no handshake cable for testing.

Hi: I don't want to use SBC to login PC. but I do want to use the SBC as PC, so I can minicom to other network device like routers,switches..etc. to clarify the problem, I try to test PC RS232 connection to a MicroTik router. and I found the rs232 pin need to use TX/RX/GND. only TX/RX is not enough. in contrast when I use SBC uart1 to connect uart2 directly via minicom, two wires TX/RX are enough to get login screen. I don't really understand the technical details, just confused about the situation.

hi: the converter is powered by orange pi pin. the strange part confused me : it is working if I use PC minicom program to control orange pi uart0, but it is not working when I use orange pi uart1 to control other network device via minicom. (flow control all disabled) I have tried to use orange pi uart1 to connect uart0 directly and it is working fine, so I think uart1 configuration is ok.

hi: my ttl part has rx/tx/gnd/vcc, like this :

Hi: I can use the rs232-ttl converter to control orange pi via PC, so I think the voltages is ok? I just don't know why ttl can not control rs232, it seems related to rs232 initialization or something?

hi: I want to use my orange pi to control some network devices which has rs232 console port. so I enable uart1 as 2 pin mode, and buy some rs232-ttl converter board. then I found these rs232-ttl converters is not working under my situation. they do work when I use my PC to control orange pi (so this is RS232 -> TTL). they don't work when I use my orange pi to control rs232 device (so this is TTL-> RS232, not working). it seems there is something difference between RS232->TTL and TTL->RS232. now I wonder if TTL->RS232 possible? or I need enable 4 pin mode and find another kind of converter for the work? thanks a lot for your help!

Hi: I was using version 5.30 at orange-pi-pc and orange-pi-one. it is very stable. I saw some irq complain about 5.35, but I don't know if these issues affect H3 boards. I use the boards as headless server with openvpn and some DI/DO. is version 5.35 stable enough for the work? or I should stick with 5.30? thanks a lot for advice.
