Support for Mikrotik RBwAP2nDr3

For Developers
1

Dear all,

I have a problem running OpenWrt (19.07.7) on RBwAP2nDr3. Image https://downloads.openwrt.org/releases/19.07.7/targets/ar71xx/mikrotik/openwrt-19.07.7-ar71xx-mikrotik-rb-nor-flash-16M-initramfs-kernel.bin starts correctly from bootp. But sysupgrade -v -n with https://downloads.openwrt.org/releases/19.07.7/targets/ar71xx/mikrotik/openwrt-19.07.7-ar71xx-mikrotik-rb-nor-flash-16M-squashfs-sysupgrade.bin causes the router to not wake up.

Two devices have gone through the sysupgrade procedure and are now not starts.

I am asking for help in running OpenWrt on these devices.

Anyone have partition dumps for older revisions? Maybe the bootloader has been changed?

Hi @karoiz

I haven't use OpenWrt 19.07 with any of my Mikrotik devices.

It should not be too much work to get OpenWrt master (ath79) running on this device, starting from the very similar devices:

The first device I checked from your dumps has RouterBoot 6.45.9 for backup & primary, so this should be fine. There are currently problems with RouterBoot v7 (beta) loading kernel from flash. If you do have RouterBoot v7, you can netinstall a v6 RouterOS, then upgrade (downgrade) RouterBoot from within RouterOS.

sysupgrade on my mipsbe Mikrotik devices does takes a long time (5+ minutes, leave it alone for 10 minutes to make sure). Something you can to do check if this is working: sysupgrade, then if the device does not boot successfully, netboot again and have a look at the firmware (and kernel) partitions. It is also good to note what the LEDs and network (tcpdump or wireshark) are doing during the sysupgrade.

If you can connect to the board console, there is a tag in the hard_config that usually can be changed to have RouterBoot output to console, but this does not provide much information. You should be able to tell if RouterBoot is successfully loading the kernel or not:

Example successful 760igs kernel load:

RouterBOOT booter 6.46.5

RB760iGS

CPU frequency: 880 MHz
  Memory size: 256 MiB
 Storage size:  16 MiB

Press any key within 2 seconds to enter setup..
