Trouble installing OpenWrt on meraki mr24

I am having trouble installing wrt on a mr24. I seem to be getting stuck on this step. Can someone guide me in the right direction. From what I understand step 5 would almost seem optional. Yet if I skip, it will not boot into wrt. What software do you use for the SCP/HTTP server?

  1. Create a recovery UBI partition. This will host an initramfs build so our board can have a failback image in case of a bad flash, or sysupgrade issue. Note you will first want to upload a copy of the initramfs image to the board (which can be done with SCP/HTTP Server). In the below tutorial note that the new partition is made to be just a bit larger than the initramfs image. You will want to do this as well.

ls -alh /tmp/openwrt-apm821xx-generic-mr24-initramfs-kernel.bin
ubimkvol /dev/ubi0 -s 5MiB -N recovery
ubiupdatevol /dev/ubi0_1 /tmp/openwrt-apm821xx-generic-mr24-initramfs-kernel.bin

This step is not optional!!!

It's especially not an option if you want to test your device by booting into the recovery to proceed.

  • 5MiB is too small, use at least 7

I use and wget directly to /tmp on the router ...after all, the file is already there.
