Re: Debian on Synology DS215j - 7 weeks ago

Thanks Bodhi, I've been looking around and not much shows up. Going back to the DS215j, I want to try to compile and use the Synology DSM kernel (v3.2.4) with your Debian DeBootstrap install. How do I compile a kernel from source and use it within a Debian Debootstrap install. I guess I'll need some of Synologies custom libraries, but I'm not sure I've searched online

Re: Debian on Synology DS215j - 8 weeks ago

This is not looking good without the docs. What is the latest SoC / NAS you'd recommend that's supported?

Re: Debian on Synology DS215j - 8 weeks ago

I put the request for releasing the Armarda 375 documentation via their Request Information contact page https://www.marvell.com/request-information.html No response at all from Marvell. Maybe because I'm a nobody and not a registered company with an NDA? Are you able to try as well?

Re: Debian on Synology DS215j - 2 months ago

Nice Bodhi! I've tested the LED/Beeps and they are working as expected. Shutdown (shutdown -h now) also works with the message: reboot: Power down qnap_power_off: triggering power-off.. I'll put in a request to Marvell for the very old Amarda 375 specification documents.

Re: Debian on Synology DS215j - 2 months ago

Bodhi, Sorry, no luck in my search. It must be under an NDA :( Is the only way to get it is from Marvell/AMD or whoever owns it by signing an NDA?

Re: Debian on Synology DS215j - 3 months ago

Synologies DSM 6.2 uses the v3.2.4 kernel which I compared to the stock kernel for the same version. To get the respective kernel sources for the armada 375: linux-3.x.txz https://global.synologydownload.com/download/ToolChain/Synology%20NAS%20GPL%20Source/6.2-25556/armada375/linux-3.x.txz Location of .config which shows the kernel version (# Linux/arm 3.2.40 Kernel Configuration): ./6

Re: Debian on Synology DS215j - 3 months ago

A puzzle indeed. Given Synologies DSM uses the 3.x Kernel, then it may be a regression in later kernels (?). I'd like to try compiling a 3.x kernel to see if it works and rule out a regression in the 6.x kernel. How do you prepare the Debian-6.6.2-mvebu-tld-1-rootfs-bodhi.tar.bz2 file (https://forum.doozan.com/read.php?2,32146)? Do you have a build script?

Re: Debian on Synology DS215j - 3 months ago

The DS215j doesn't support POE (https://global.download.synology.com/download/Document/Hardware/DataSheet/DiskStation/15-year/DS215j/enu/Synology_DS215j_Data_Sheet_enu.pdf). Would've been a cool feature though.

Re: Debian on Synology DS215j - 3 months ago

Quotebodhi Either that, or the kernel misidentified the chip. Looking at the driver source, it looks like the 88E1510 is used as a catch all for the family of 88E151x PHY chips. It also contains a workaround for the 88E1514 bug. ./linux-stable/drivers/net/phy/marvell.c ... static int m88e1510_config_init(struct phy_device *phydev) { static const struct { u16 reg17, reg16;

No luck re-running sgmii (armada-375-synology-ds215j_sgmii.tar) but the information maybe useful: root@debian:~# ethtool eth0 Settings for eth0: Supported ports: [ TP MII FIBRE ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Supported pause frame

Re: Debian on Synology DS215j - 3 months ago

Thanks Bodhi. I started looking for the specification documents for both the Marvell Amada 375 (88F6720) and the ETH Marvell 88E1514. Which may help with the DTS. I cannot find anything for the Marvell Amada 375 (88F6720) (maybe under NDA???...), even the kernel docs only mentions the product brief and not the hardware specs. https://docs.kernel.org/arch/arm/marvell.html Armada 375 Flav

Re: Debian on Synology DS215j - 3 months ago

Another approach I've tried is to extract the DTB and convert it to a DTS from the Synology DSM installation PAT file. However, it has not worked, see below. Download DSM from: https://archive.synology.com/download/Os/DSM/6.2.4-25556 Extract file: $ binwalk -e DSM_DS215j_6.2.4-25556.pat $ cd _DSM_DS215j_6.2.4-25556.pat.extracted/ Install extract-dtb tool: $ pipx ins

Re: Debian on Synology DS215j - 3 months ago

Do you think the problem lies in the DTS (missing some parameter setting or adjustment) or it's a problem with the kernel/driver?

Re: Debian on Synology DS215j - 3 months ago

Re: Debian on Synology DS215j - 3 months ago

Hi Bodhi, I just compared this latest DTS (armada-375-synology-ds215j_mii.tar (20 KB)) with the version from 20th Jan, and they are the same. They both contain phy-mode = "rgmii-id"; . Should it be phy-mode = "mii"?

by ZooMoo - Debian

Re: Debian on Synology DS215j - 3 months ago

Here are the results for using the DTS from https://forum.doozan.com/read.php?2,138851,138913#msg-138913. According to ethtool the ports show three options, TP, MII and Fibre whilst the Synology DSM OS only has TP/MII. Eth0 then wrongly sets the port to Fibre when an ethernet cable is plugged in.

I've compared the output of ifconfig, ethtool, etc between the stock DSM OS and debian. Booting the stock DSM OS I can connect to the network so it's not a network issue.

The router and cable are the same ones I used when you got me to "setenv ipaddr" whilst in u-boot. ping worked in the case of u-boot. Even if ping works within u-boot, could something else be wrong with the router/cable? Strangely, when I unplug the eth
