  1. Hello, Is there a way (maybe using sysfs) in Linux to manage the brightness of the LED in the front of the NAS ? I found no information about this in the wiki: https://wiki.kobol.io/helios64/led/ or https://wiki.kobol.io/helios64/front-panel/ Thanks.
  2. That's sad. Any information about the jumbo frame support on the working ethernet port ?
  3. Hello, I am trying to setup LACP aggregation on my helios64 between the two ethernet ports on the helios64 and I noticed I can set the MTU of the 2.5G port up to 9000 but the 1G ethernet port top at 1500. I use the 2.5G port as 1G as my network switch is gigabit only. Can you confirm that the 'first' port (aka the 1G port) is not jumbo frame compliant ? This error shows up when I try to change the size: rk_gmac-dwmac fe300000.ethernet eth0: must be stopped to change its MTU when the command is used: # ip link set mtu 3000 eth0 RTNETLINK answers: Device or resource busy Even when the link eth0 is down, the MTU cannot be changed.

  4. Hello, A GPS module ublox is connected to a odroid c2 board on GPIOX.12 and GPIOX.13 for the RX and TX and GPIOX.10 for the PPS. The board is running the stable kernel 4.19.42-meson64 from Armbian based on Debian stretch which was dist-upgraded to Debian buster. I am trying to get the /dev/pps0 entry using GPIOX.10 to finish the chrony setup but I cannot find the correct syntax in the DTS file. Any pointer or idea ? I try either of the gpios line below, none of them seems to be correct. pps { gpios = "< 0x1e 0x66 0x0 >"; #gpios = "<&gpiox 10 GPIO_ACTIVE_HIGH>"; #gpios = "< 0x66 >"; assert-falling-edge; compatible = "pps-gpio"; }; The file include/dt-bindings/gpio/gxbb.h#L122 in the Linux kernel tree show the value of GPIOX.10 is set to 102 (aka 0x66 in hexa). After reboot, the pps-gpio module is loaded and cannot find the GPS connected. # dmesg | grep -i pps [ 1.414780] pps_core: LinuxPPS API ver. 1 registered [ 1.414783] pps_core: Software ver. 5.3.6 - Copyright 2005-2007 Rodolfo Giometti <giometti@linux.it> [ 5.460824] OF: /pps: could not find phandle [ 5.460835] pps-gpio pps: failed to get GPIO from device tree [ 5.460849] pps-gpio: probe of pps failed with error -22 The previous pps-gpio kernel module had the option for the gpio_pin which seems a bit easier to use :-/ Thank you.
