Hi Guys,
My USB -TTL arrived and i have managed to access the serial port during boot.
Dump posted here - [https://pastebin.com/rfnFYQm4](Meraki MX65 boot output)
Most relevant parts ( i think)
U-Boot 2012.10-00101-g93bc206
Linux version 3.4.111 (jdizzle@x) (gcc version 4.8.3 (GCC) ) #6 Wed May 4 11:23:30 PDT 2016
Linux version 3.4.109 (tpassaro@tpassaro-imac) (gcc version 4.8.3 (GCC) ) #15 SMP Sun Jan 10 21:10:58 PST 2016
BusyBox v1.20.2 (2015-12-18 17:37:54 PST)
It also seems like this is very similar (if not identical to the MX64 / MX64W hardware systems)
Meraki Z1 seem similar as well so i am going to read up on how they work with Openwrt and take it from there.
I have never worked on the hardware /flashing level before so any tips / guides would be appreciated.
