Alrighty, I've written a little Expect script for Windows XP - it shouldn't be too hard to adapt it to Linux or other OSes.
I am using Expect for Windows NT and Solarwinds TFTP Server 8.0
EDIT: I actually was using Solarwinds TFTP Server 6.0 during testing and switched to version 8.0 late in the piece. The problem is - I can't get version 8.0 to work with RedBoot! If you can find version 6.0 anywhere, use it. (I still have a copy of the install file)
You just put your linux kernel and rootfs image files in the same directory as the meraki-flash.bat batch file and it does the rest. Expect even runs the TFTP server for you. You just need to make sure the TFTP server is set to "C:\TFTP-Root" for it's root dir, and that it's security setting is set to "Transmit Only" or "Transmit and Receive files". The script assumes all applications are installed in their default directories, and that the hard drive is C. And of course, the LAN interface on your Windows PC needs to be 192.168.84.9 (netmask 255.255.255.0).
I've opted for a 1.0MB linux kernel partition instead of 1.5MB. This leaves room for a slightly larger rootfs. I don't expect that the OpenWRT linux kernel will ever be larger than 1.0MB - if it ever is, it's a simple matter to edit this script.
The script pauses 3 minutes while the Linux image is written to flash, and 5 minutes while the rootfs is written to flash. So the whole script takes about 9 minutes to execute. After Expect changes the RedBoot boot script, it should reset the Meraki and OpenWRT should begin it's firstboot procedure.
I will shortly put together a zip file with all the install files and a batch file that installs them and makes the appropriate registry changes to the TFTP Server config.
I execute the expect script via a batch file:
meraki-flash.bat
@ECHO OFF
CLS
SET linux_file=openwrt-atheros-2.6-vmlinux.gz
SET rootfs_file=openwrt-atheros-2.6-root.squashfs
REM The above files are copied to the tftp server root directory so the meraki can load them
ECHO .
ECHO .
ECHO About to erase the Meraki's memory
ECHO and flash %linux_file% and %rootfs_file%
ECHO .
ECHO The Meraki should be turned off now
ECHO Power it after the first ping timeout...
ECHO .
ECHO Press Ctrl-C to abort... or...
PAUSE
ECHO .
ECHO .
ECHO Confirm - Ctrl-C to abort... or...
PAUSE
COPY ".\%linux_file%" "C:\TFTP-Root\" || ECHO . && ECHO Please place %linux_file% in the same directory as meraki-flash.bat && PAUSE && EXIT
COPY ".\%rootfs_file%" "C:\TFTP-Root\"|| ECHO . && ECHO Please place %rootfs_file% in the same directory as meraki-flash.bat && PAUSE && EXIT
"C:\Program Files\Expect-5.21\bin\expect.exe" ".\data\meraki-redboot.exp" %linux_file% %rootfs_file%
REM Clean up TFTP-Root directory
DEL "C:\TFTP-Root\%linux_file%"
DEL "C:\TFTP-Root\%rootfs_file%"
ECHO meraki-flash.bat ends here
