Meraki MX64 Uboot not loading bin file

Installing and Using OpenWrt
1

Hi,

I am trying to install OpenWrt from Clayface instructions :

After trying many USB drives and formatting combos I got on the serial and find out that the u-boot is trying to load a different file name:
openwrt-bcm53xx-generic-meraki_mx64-initramfs.bin
and not the bcm5862x I was expecting... it goes without saying that I have tried to rename the file but with no result:

(Re)start USB...
USB:   Before reset, USB clk enable register is: 000002dd
Before reset, USB clk enable register is: 000002dd

Wrong Image Format for bootm command
ERROR: can't get kernel image!

so now I am not able to continue, nor to find a bmc53xx initramfs file... any suggestion on what could I have done wrong and how to move forward?

here some environment info:

do you really want an AP with crippled wifi ? seems rather pointless ...

The device can be used as a wired only router and has 2GB of RAM which is not bad. The full discussion of adding support is in the following thread:

There have been a few changes between Clayface initial work and the device getting official support. To install OpenWrt you will need to use a recent OpenWrt initramfs and not Clayface file. Unfortunately OpenWrt does not supply the initramfs in the download section so you will have to build your own.

The full install instructions are over here:

@XXmode1XX I just checked the wiki page in @frollic post and near the end of the page are 2 download links to pre-compiled initramfs files. You should be able to complete the install using one of those.

Eureka!

the bin form the Clayface git are not readable from the U-boot installed...

so I re-wrap the bin with this command:

mkimage -A arm -O linux -T kernel -C none \
  -a 0x80001000 -e 0x80001000 \
  -n "OpenWrt MX64" \
  -d openwrt-bcm5862x-generic-meraki_mx64-initramfs-kernel.bin \
  openwrt-mx64.uImage

then I saved it on the USB stick and load it manually on memory

usb start
fatload usb 0:1 0x80000000 openwrt-mx64.uImage
bootm 0x80000000

then I have transfer the squashfs bin with a Wget ( you will need to set up a local webserver) and proceed with the sysupgrade...
