znoxx Posted February 13, 2017 Posted February 13, 2017 OK, not sure how much I can do here. Legacy stuff uses ARISC core to shutdown, so it can kill both the clocks and the power reliably. @zador.blood.stained, first of all - thanks a lot for your efforts. I totally agree with hojnikb - may be downclock everything, turn off ethernet, hdmi and usb (if possible, of course). In PC2 case, I think that will be quite enough, since previous versions raised power consumption and it was scary to leave board in this state unattended - things were too hot. 0 Quote
zador.blood.stained Posted February 13, 2017 Posted February 13, 2017 (edited) Maybe revert changes and downclock the core, so it works on all boards and don't eat as much power ? Well, there is a shutdown bit in the syscon register it's for EMAC, I must have scrolled too far while reading the datasheet, so it may work too. It's just a matter of determining what's more power efficient and reliable. It doesn't need to work on all boards, since we have only 2 arm64 board families (that have shutdown via PSCI/ATF). Edited February 21, 2017 by zador.blood.stained No shutdown in syscon 0 Quote
claus2006 Posted February 14, 2017 Posted February 14, 2017 I'm having a problem. orangepipc2 connects over wifi and cable but it does not surf and does not update. NetworkManager is locked for editing. Using the nm-connection-editor command as sudo I can edit. But it does not connect. I have edited the sudoers file. I changed dns to 8.8.8.8 without result. I modified several things on the router without success. ping command works on any site. If I use the smartphone hotspot it works very well. sorry googletranslation. 0 Quote

If you have DHCP server, your wired connection should work out of the box. You don't need to do anything. On all boards this is the same. OPi PC2 is under development and network could be temporally broken. Check today's (automated) build. 1 Quote

tkaiser Posted February 16, 2017 Posted February 16, 2017 But U5 is a SY8008B chip Please remember that we already had something similar with other OPi boards. On OPi One according to schematic SY8113B is used where in reality AX3833 is soldered to the PCB.

Allfifthstuning Posted February 20, 2017 Posted February 20, 2017 There's a great audio repository for Debian/Ubuntu KXstudio, which I use on my laptops along with either Debian of (K)Ubuntu. I understand that I can't use this on the earlier PC One board due to the fact that the SSE2 instruction set isn't supported. Does anyone know if this is still the same for this newer board?

Hans SSE2 is a x86 specific set of instructions, so likely those packages are compiled for x86 only and thus unusable on every ARM board ever made (that includes PC2) 0 Quote
znoxx Posted February 20, 2017 Posted February 20, 2017 Hi All! Well, there is a shutdown bit in the syscon register, so it may work too. It's just a matter of determining what's more power efficient and reliable. It doesn't need to work on all boards, since we have only 2 arm64 board families (that have shutdown via PSCI/ATF). Any updates on shutdown ? I think that "custom shutdown hook" is still needed. Because when I issue the "shutdown -H" - to halt system without power down (to avoid reboot) it still goes to 600 mA consumption So please can you point me to the right places in sysfs to 1) Set clock to lowest possible speed 2) Turn off HDMI completely 3) Turn off Ethernet (i think I can go with "ifdown eth0", but not sure this is correct) Not sure USB must be turned off here, because, well you can have HDD mounted at this time... 0 Quote
zador.blood.stained Posted February 20, 2017 Posted February 20, 2017 Any updates on shutdown ? No updates yet. I'll try to look at it maybe this week. 0 Quote

Want to look into IRQ redistribution for PC2 and MiQi board soon. http://sprunge.us/cZOb is the first half. If you point me to a specific image you want me to run, I'll DL and burn it and get the data. I've never used any of their images, so I'm unfamiliar with their site. 1 Quote
tkaiser Posted February 21, 2017 Posted February 21, 2017 @HAK @willmore: Thank you both, looks good and like the job can be done without having to differentiate between legacy and mainline kernel (sunxi-mmc, usb and '1c30000.eth' seem useable as regex) 1 Quote
znoxx Posted February 21, 2017 Posted February 21, 2017 Well, I added "temporary(?)" shutdown hook, because as I told before even "shutdown -H" (halt instead of poweroff) forces board to go to 600mA consumption and producing some heat . What it does: Gets minimal possible frequency from list Sets it Downs Ethernet Also I tried to turn off framebuffer, but usual recipes for blanking fb0 didn't worked... echo 1 > /sys/class/graphics/fb0/blank gave me only "Input/output error", but cursor blinking "off" worked, so I decided to leave it =). May be it will save some small amount of power =). So the script is below, just create a pre_shutdown.sh executable in /usr/local/bin: #!/bin/sh ###Get minimum CPU Speed MINSPEED=`cat /sys/devices/system/cpu/cpufreq/policy0/cpuinfo_min_freq` echo "Setting CPU to $MINSPEED" echo $MINSPEED >/sys/devices/system/cpu/cpufreq/policy0/scaling_min_freq echo $MINSPEED >/sys/devices/system/cpu/cpufreq/policy0/scaling_max_freq echo "Trying to turn off HDMI..." echo "Only cursor for now..." echo 0 > /sys/class/graphics/fbcon/cursor_blink echo "Down the network..." ifdown eth0 Now, as @tkaiser advised, add it to /etc/init.d/armhwinfo right in "stop" section, before unloading modules. Something like this: case ${BOARD_NAME} in "Orange Pi PC2") /usr/local/bin/pre_shutdown.sh ;; esac # some kernel modules are known to crash the kernel on shutdown (an example If anyone has an idea to shut off HDMI via sysfs, thanks in advance. If you don't feel adventurous and don't want to edit /etc/init.d/armhwinfo, you can run it manually before shutdown (mind eth0 down) sudo /usr/local/bin/pre_shutdown.sh && sudo shutdown -h now --or-- sudo /usr/local/bin/pre_shutdown.sh && sudo shutdown -H now Measurement results ( I used not the latest build, since shutdown leads to reboot) No shutdown hook: 600ma Only CPU downscaling: 270ma CPU downscaling && Ethernet down: 170ma Same numbers with cursor blinking off, but may be my "usb doctor" has not enough prescision to handle this . Just as reference - 100ma after shutdown with legacy kernel/uboot, if I'm not mistaken. So now numbers are comparable... May be it will help someone. Looking forward for "true shutdown" 0 Quote

May be it will save some small amount of power =). That won't work, because simplefb driver doesn't know how to do that. However, all clocks/gates/resets should be properly disabled during shutdown, if they were correctly specified in kernel and DT (at this point it is hard to tell). 0 Quote

znoxx Posted February 22, 2017 Posted February 22, 2017 Updated not-the-latest build via apt-get upgrade. After system halt consumption is 300ma instead of 600 without pre-shutdown sequence. Great, so far. But now according to armbian monitor cpu clock is almost always 1296 Mhz. Even if system load is 0.01. Is it normal ? As far as i remember system was auto downclocked without load. 0 Quote

As far as i remember system was auto downclocked without load. Why not checking what might be wrong on your own? Using cpufreq-info and comparing with /proc/config.gz is one option to detect mismatches between userspace settings and kernel and there is /sys/devices/system/cpu/cpu0/cpufreq/* to explore. 0 Quote
