  1. I tried to lower the DRAM clock by setting CONFIG_DRAM_CLK=240 in the kernel config. Sadly this did not make a difference. Still I am thinking about to maybe get something out of the wifi. I do not need it at full speed. 10MBits would be totally enough. Setting Tx-Power with iwconfig also made no difference. And Bit Rate was not settable at all. Maybe I could fall back to use only b/g wifi and deactivate n. Is that possible?
  2. Greetings, after a long time I am playing with my old Banana Pi Pro again. This time with the intention to probably use it on IoT purposes. That implies I only need WIFI and the GPIO pins. Which gives some opportunity to save power by powering down every thing else which is not needed. My first approach here is to strip down everything from the device tree I don´t need. That means everything related to: framebuffer hdmi lcd sata display engine ethernet video codec usb ir gpu/mali That resulted in a drop in power consumption in idle from: ~0.990 - ~1.330W to: ~0.700 - ~1.000W Roughly 0.3W lower consumption. Furthermore I underclocked the CPU to the minimum of 144MHz with power save governor. Resulting in a idle power consumption of: ~0.670 - ~0.720W I also tried setting the default kernel tick rate from 250HZ to 100HZ but that gave no measurable gains. And just for curiosity I deactivated the WIFI from the device tree resulting in a consumption of: ~0.470 - ~0.520W Thats pretty much for one needed component and I am asking myself if there is some saving potential here. So I found out from iwconfig that power management is not enabled. Enabling it by changing /etc/NetworkManager/conf.d/20-override-wifi-powersave-disable.conf wifi.powersave from 2 to 3 changed what iwconfig shows. But it has no influence on power consumption at all. So my questions here are the following: Is there a possibility to save power on wifi? Are there other things I can do aside from these I have done?
  3. Thank you again dear Igor This works and everything is fine now
  4. Hello, at first I want to thank you for your great work Igor 2 Days ago I installed the new version 5.00 Vanilla Kernel armbian for BananaPro on my SD card. And I was so glad to finally see a working wifi for BananaPro with mainline kernel. Today I did an apt-get update and apt-get upgrade. Ever since there is no more a wlan0 interface. Have tried ifconfig and iwconfig. It seems to be, that there was installed a new kernel image. What can we do to get it working again? Also ReleaseHistory says there is a version 5.01 but the download link for BananaPro Vanilla Jessie still leads to a version 5.00 link. Kind regards Wolf
