Support for Mikrotik Metal 2SHPn

For Developers
1

Hi all!

Has anyone had any luck with installing openwrt on the Mikrotik Metal 2SHPn yet?

I have tried following the common mikrotik instructions (https://openwrt.org/toh/mikrotik/common), and have loaded the 18.06.1 ar71xx mikrotik image (vmlinux-initramfs.elf), and this seems to run, the device holds it and doesn't attempt to reboot back to RouterOS, however there are no signs of life when doing so - nothing on the LEDs and no activity via the ethernet interface (have done a pcap and can't see any packets coming through).

(https://downloads.openwrt.org/releases/18.06.1/targets/ar71xx/mikrotik/openwrt-18.06.1-ar71xx-mikrotik-vmlinux-initramfs.elf)

Anyone made it any further than this?

Thanks

Are you trying to work on supporting this device?

I don't see this devices listed in the Table of Hardware:

https://openwrt.org/toh/start?dataflt[Brand*~]=mikrotik

I have it running (quick and dirty) with wireless and ethernet, txpower is only 17db, but I think the device has an amplifier.

I just edited:
target/linux/ar71xx/files/arch/mips/ath79/mach-rb750.c
and changed it to match the device name:

static void __init rb751_setup(void)
{
        rb750_setup();
        ath79_register_usb();
        rb751_wlan_setup();
}

MIPS_MACHINE(ATH79_MACH_RB_751, "groove-5s", "MikroTik RouterBOARD Metal2",
             rb751_setup);

second file was:
target/linux/ar71xx/patches-4.9/701-MIPS-ath79-add-routerboard-detection.patch

+           strstr(arcs_cmdline, "board=groove-5s") ||

Your a wizard humnab - thankyou!

Which version did you use here? I tried with the latest 18.06 and got basic ethernet and commandline, but no luci and no wireless. And then tried with the latest master and couldn't get it to boot either. Bit hard to figure out whats going on without a serial connection.

Thanks again

I used 18.06.1, I will try to send you patches against plain 18.06.1 this weekend. If I remember correctly I followed this guide https://forum.archive.openwrt.org/viewtopic.php?id=16599 to install luci an enabled it in menuconfig. I will check this this weekend also, I did my tests some weeks ago and don't know if I remember this steps correctly.

This topic here is about adding OpenWrt support for this device.
Please split your request for OpenWrt firmware and wifiranger-linke software package into separate topics.

How is the build for this router coming along? I don't want the wifi ranger - I just want OpenWRT.

Hello

I got same device and want to put openwrt on it.
I tried to compile openwrt but device don't ping after bootp (I see device taking file for boot).
I am using 18.06.9
I modified the two files as @humnab shown and compiled openwrt using https://openwrt.org/docs/guide-developer/toolchain/use-buildsystem#building_images

I have some questions / issues if someone have the answers :
How do you identify with no doubt the device name (groove-5s) ?
from RouterOS mine is RB "Metal 2SHPn"

I have not file tagged 'factory' in build folder but it it the one required for booting device. Why ?

If anyone have a working installation, can him provides steps to have openwrt running ?

Thanks !
