I can confirm that with kirkwood-nsa310a.dtb the hardware monitoring and fancontrol works flawless :-) Readout of three temps and setting the pwm output can all be achieved by lm85. As expected no red USB LED in /sys/class/leds anymore. So obvisouly there are at least three variants of the NSA310.by sebr - Debian
Hi, I have disassembled he device and verified that the circuitry to control the fan speed is identical with the application note in the datasheet and connected to pwm1 / tach1. The other pwm outputs not do anything. According to the datasheet. after power-on, the initial pwm duty cycle is 100%. The LM9600 is listed as compatible with the lm85 module, see here: https://web.archive.org/web/20150by sebr - Debian
Thanks for you answer. sensors is able to read the rpm of the fan but not able to set the fanspeed (checked with pwmconfig). The adt7475 module is loaded. Since I was running the NSA310 for a while with the stock firmware I can assure you that there is a fancontrol in software. Also now since running debian on the device the fan is constantly spinning at max rpm is evidence to me that the fanspeby sebr - Debian
Hello pbg4, this is the link I posted above already and installing fan3xxnsa has no effect on the fanspeed. Reading through the instructions there at least should be able to set the fanspeed manually by echo 1 > /sys/class/i2c-dev/i2c-0/device/0-002e/pwm1_enable echo 0 > /sys/class/i2c-dev/i2c-0/device/0-002e/pwm1 This should turn the fan off but doesn't. Any ideas why?by sebr - Debian
Does the NSA320 have the ability to control the fanspeed by software? Afaik only the NSA310 has this capability among all the Zyxel devices.by sebr - Debian
Thanks für your reply. This thread is about the hwmon module. But for now I am just trying to set the fanspeed on the NSA310 which is simply done by writing to /sys/class/i2c-adapter/i2c-0/0-002e/pwm1 like it is done here: click and there: click But that doesn't work.by sebr - Debian
I just set up a NSA310 (not "s") with the latest jessie rootfs, kernel 4.4 and latest uboot. So far I got everything working like LEDs, buttons etc. But how can I control the fan speed? It is always running at max. rpm.by sebr - Debian
Recently I have flashed bodhi's latest uBoot on a Zyxel NSA310. I havent flashed new envs and booting debian from USB worked flawless. But unfortunately I cannot boot back to stock OS in flash anymore! After tweaking the envs in uBoot it picked up the kernel image but then stalls without any further progress after: Starting kernel ...

I also struggle to get back to boot the stock OS with the latest u-boot on NSA310. here is the old envs i saved before flashing latest u-boot: bootargs=console=ttyS0,115200 mtdparts=nand_mtd:0x100000(uboot),0x80000(uboot_env),0x80000(key_store),0x80000(info),0xA00000(etc),0xA00000(kernel_1),0x2FC0000(rootfs1),0xA00000(kernel_2),0x2FC0000(rootfs2) root=/dev/nfs rw init=/init bootcmd=nand readby sebr - uBoot
Is anybody running iSCSI on a NSA325 and could do some benchmarks and report back the results here?by sebr - Debian
Hope to see the tutorial soon, cannot wait to try on my 310.by sebr - Debian
I have the latest rootfs and kernel running on my NSA325 from USB thumbdrive. In fstab there is already the noatime option set. What other tweaks are advised to expand the lifetime of the USB stick? Or is that not neccessary anymore nowadays? I still remember posts from people that got their flashdrive killed within weeks - but that was some years ago.by sebr - Debian
Well thanks for your quick reply. I already read through tons of posts here but still I might have been missing something. What this automated installation does is exactly what I want: boot to debian if there is a usb key attached, else boot to stock. So that for testing purposes I can easily switch. There is no need for a new u-boot if I am not mistaken. I really have no clue what went wrong.by sebr - Debian
Yeah, it stated bad magic number. In u-boot I did a resetenv. Now the device is at least booting the stock firmware again. But it seems as it does not pick up anything from usb anymore to boot from :-(by sebr - Debian
I have tried this on my NSA325 with Stock FW 4.80. Never flashed uboot or anythign else before. Unfortunately now the device is in a reboot loop with all LEDs flashing after a few seconds and then reboot. How to fix this?by sebr - Debian
