Installation of Meraki MR18

Installing and Using OpenWrt
1

Hi All

I have been able to install Openwrt upon three of my 15 MR18 so far.
Here is what I did to get them.

  1. I followed this website https://openwrt.org/toh/meraki/mr18/jtag?s[]=nano*&s[]=plus*#flashing_openwrt
  2. I used my openocd raspberry pi config
adapter driver bcm2835gpio
bcm2835gpio peripheral_base 0x3E000000
bcm2835gpio speed_coeffs 194938 48
#bcm2835gpio_jtag_nums 11 25 10 9
adapter gpio trst 7
adapter gpio tck 11
adapter gpio tms 25
adapter gpio tdi 10
adapter gpio tdo 9
  1. On JTAG I connected pin 14 from Meraki (VCC) connect directly to VCC 3,3V on Raspberry PI (pin 1), pin 2 (GND) on Meraki to pin 25 on Raspberry PI.
  2. I used a Raspberry PI 3B, with current version of raspberry pi lite image. I had no devices connected to the raspberry pi.
  3. I ssh into the raspberry pi and did all the installation this way.
  4. I am randomly getting there. I am not sure when timing of running openocd to break to the Meraki MR18 boot sequence.
  5. 12 more MR18 to convert.
  6. I will try to make a blog post and youtube video. So in the future others can just follow the steps

I now have been able to flash 13/15 units, Two where faulty.
I also made a screen cast of what I done, yet to edit the video.

What is the issue with the faulty ones?

One kept booting to a menu to press like options one to five and the other could never get port 4444 up, got to port 3333 and hung there, did it about 40 times to no avail.
