Hi, I am trying to program a Meraki MR18 using a raspberry pi model A. When I stop the boot using the Openocd I am not able to do the telenet as there is no $. I have tried this repeatedly stopping it at different points and still can't get it to work. Any help please?
How are you powering the MR18, for the first five MR18 I converted I found PoE to be a non starter and had to use a power supply.
Which method are you using?
Thanks. Using a power supply. The method is https://openwrt.org/toh/meraki/mr18/jtag
ok, same method, so you have two ssh terminals, one for uart and one for jtag?
I only ever got this working on a rpi model b.
Yes have 2 terminals. The uart stops and the jtag one says it has halted but no $ to be able to do anything.
That's an indicator you have not been quick enough.
your second screen is far too far booted, you need to be in the bootloader
Hi, I am stopping it earlier but it still doesn't go to a prompt for telenet. I switch the power supply on for the MR18 then hit enter on the keyboard within a second or 2. Any other thoughts?
Plenty of suggestions,
Are you using the Pi as a desktop pc?
How are you turning the mr18 on and off, my preferred process was an extension lead with an on off switch.
Thanks for getting back to me. Yes using the Pi with desktop environment. Using a power supply and switching on at the wall. Added connection for GND and VCC as suggested by someone for the jtag interface. Raspberry Pi is one of the first ones model b.
Hi, I am going to give up on trying to reprogram them. Would you be interested in them? I have 4, you can have them for the price of postage!
Which country are you in?
The UK, Scotland.
