Openscope MZ reboots on connection attempt - can't connect


Recommended Posts

Hi, 

Following a failed firmware update. I'm unable to connect to my Openscope MZ (rev F) to go through the bootloader process of recovering the firmware.

The scope boots as normal and connect to wifi. I can also connect via serial and can see the terminal output in PuTTY etc. If I enter the IP address of the scope in the browser the scope detects the connection and redirects to waveformslive.com.

However as soon as I try to connect (either via agent or via network), the scope immediately reboots - LD5 flashes once, then LD6, LD5, LD6 in rapid succession and the scope reboots, and I get the error 'Unable to communicate with device' in waveformslive.

I've also tried connecting in bootloader mode, but still cannot connect. LD5 flashes once and once more after a pause - waveformslive informs "unable to connect with device".

With the scope connected via serial connection and with a terminal open, attempting to add via network the scope reports "New client detected" then "Option page detected" and the immediately reboots.

I've tried to connect using WIndows 10, 7 and OSX using different USB cables but with no success.

Terminal output on reboot is:

Hi @frokostfredag,

I have asked another engineer more familiar with the OpenScope MZ to take a look at this.

An initial question that I have is was this the first time you were using the OpenScope MZ or the first time that you were attempting a firmware update?

Thanks,
JColvin

Hi @frokostfredag,

That's some odd behavior that you're describing there. There is one thing I'd like you to try to debug this, and that's to enable the console output in WaveForms Live before trying to connect to the device. I'm hoping that this lets us see what command is causing the OpenScope to choke. You can do this by going into the Settings page, opening the Advanced section and clicking on Change Console Log. Set this to Console, then open the developer tools for your browser. For Chrome and Firefox this is Ctrl+Shft+i. The commands and their responses, plus some other additional information will be printed in the console here as you use WaveForms Live to configure the OpenScope. 

I would appreciate it if you could share the results with me, and together we will get to the bottom of this.

Hi @frokostfredag,

I got to talk with AndrewHolzer a bit more and learned that the firmware on the OpenScope MZ is corrupted and it would need to be re-flashed via the JP2 header. If you happen to have something like a chipKIT PGM or PICkit3, we can provide you with further instructions on restoring the device, otherwise I have sent you a PM with some further instructions.

Thanks,
JColvin
