  1. Hi When I run `cat /proc/cpuinfo`, the Features line shows the following features Features : fp asimd evtstrm aes pmull sha1 sha2 crc32 cpuid But doesn't the H5 support neon and vfpv4? Anyone know why they aren't shown? Thanks $ cat /proc/cpuinfo processor : 0 Processor : AArch64 Processor rev 4 (aarch64) Hardware : sun50iw1p1 BogoMIPS : 48.00 Features : fp asimd evtstrm aes pmull sha1 sha2 crc32 cpuid CPU implementer : 0x41 CPU architecture: 8 CPU variant : 0x0 CPU part : 0xd03 CPU revision : 4
  2. Is H5 actually safe to operate close to 105C? I see that the CPU shuts down only at 105C https://github.com/armbian/build/blob/8f4ab52b6ea806a69eec3f4ad7adbaeb5cd0f1b4/patch/kernel/sunxi-next/ths-29-add-correct-h5-thermal-zone.patch Is it not a bit too adventurous to allow operation at such a high temperature?
  3. Just an update: I thought it might be just that board, so I've just tried another PC2 unit but I'm not getting thermal throttling on it either. It also shuts down around 90C.
  4. Can I ask at what temperature should thermal throttling start to kick in? I'm now using a more powerful PSU (5V 3A) and it's still the same. Here's my output: http://ix.io/1EHF Cheers
  5. You're right. Here's the new output: $ sudo armbianmonitor -m Stop monitoring using [ctrl]-[c] Time CPU load %cpu %sys %usr %nice %io %irq CPU C.St. 16:55:19: 1368MHz 0.82 4% 0% 4% 0% 0% 0% 58.2°C 0/15 16:55:25: 240MHz 0.76 0% 0% 0% 0% 0% 0% 58.8°C 0/15 16:55:30: 240MHz 0.70 4% 1% 1% 0% 2% 0% 63.2°C 0/15 16:55:35: 120MHz 0.64 1% 0% 0% 0% 0% 0% 60.1°C 0/15 16:55:41: 1104MHz 0.99 70% 1% 69% 0% 0% 0% 75.1°C 7/15 16:55:48: 1104MHz 1.23 100% 0% 99% 0% 0% 0% 81.6°C 7/15 16:55:55: 1104MHz 1.73 100% 0% 99% 0% 0% 0% 86.9°C 7/15Connection to 192.168.100.134 closed by remote host. It's clear that the CPU frequency isn't being throttled down even when the temperature was approach 90C. Is this normal for the PC2?
  6. Hi I've noticed that thermal throttling doesn't work on the OPi PC2. I'm on 5.75. I've tried armbianmonitor -m but it doesn't give me the CPU frequency: $ armbianmonitor -m Running unprivileged. CPU frequency will not be displayed. Stop monitoring using [ctrl]-[c] Time CPU load %cpu %sys %usr %nice %io %irq CPU C.St. 14:45:40: --- 0.11 12% 0% 11% 0% 0% 0% 54.9°C 0/15 14:45:45: --- 0.10 0% 0% 0% 0% 0% 0% 55.3°C 0/15 14:45:50: --- 0.09 0% 0% 0% 0% 0% 0% 55.2°C 0/15^C Nonetheless, I get the frequency using cpufreq-info. It remains at 1.1GHz even when the temperature is around 88C. The board just shuts down when it hits 90C. Shouldn't it thermal throttle? My /etc/default/cpufrequtils looks like this: # WARNING: this file will be replaced on board support package (linux-root-...) upgrade ENABLE=true MIN_SPEED=120000 MAX_SPEED=1400000 GOVERNOR=ondemand Anyone know why thermal throttling isn't working? Thanks
  7. Hi Does anyone know if it's possible to completely disable HDMI/GPU in fex? Thanks
  8. Hi Does anyone know if the OPi Lite's WiFi is meant to automatically reconnect if the AP reboots or disappears and then comes back? What is the default behaviour supposed to be? Is it meant to automatically scan nearby networks? Thanks
  9. Sure. I just like the Zero's small size. If I'm understanding @tkaiser correctly, disabling a module in the fex switches off the component completely. That is, at no point in time the component is powered up. But how does this actually work on low level? Is XR819's power line an output of the SoC? So the fex strictly defines the state of the power line?
  10. Hi I'm looking at how the WiFi chip is powered but I'm slightly confused. You said to unsolder R69, but is there a resistor across it though? Isn't it just 2 pads? Same for R66. You'd want to solder the wire only to the pad on the positive side too - right? Is WIFI-POWER-EN in the schematic PA20? Thanks
  11. Sure. I'm just learning and trying to see what's off and what's not. Looking at that FEX, how do you tell that PA20 is the port for the WiFi chip? I'm not sure if I'm understanding it right, but if it was disabled shouldn't module_power0_vol (power0 voltage?) be 0 instead?
  12. But isn't the WiFi chip powered (and perhaps radiating?) even before the driver is loaded? The driver shouldn't power the chip though - right?
  13. Oh, my bad. Re WiFi, is there a way to disable it completely. That is, even during boot. My reading is that (sleep 60 && echo 000 >/proc/driver/wifi-pm/power) & can only be executed in shell. I wonder if there's a way to have it disabled before the shell is loaded (perhaps in BIOS?).
  14. Does anyone know if the Zero's on board WiFi chip XR819 can be disabled? The RJ45 is disabled by default, so there must be a way to disable the XR819 - right? Any thought appreciated.
