Description

Hello all.

I am testing RouterBoard R52n-M on RB435G (680MHz) system with OpenWRT 14.07, downloaded from here https://downloads.openwrt.org/barrier_breaker/14.07/ar71xx/mikrotik/ and sometime after launching iperf in UDP mode, system restarts.

I did try to install a trunk version (r48688) but was not successfull.

Thanks.

14.07 is unsupported/outdated. Recent stable version is 15.05.

https://downloads.openwrt.org/

You are telling you can not install recent trunk. Why? Please report those error.

Hi.
Version 15.05 doesn't have a openwrt-ar71xx-mikrotik-vmlinux-initramfs.elf file in https://downloads.openwrt.org/chaos_calmer/15.05/ar71xx/mikrotik/ .
I tried r48688 but didn't boot. I'm going to open a new ticket regarding that.

Thanks.
