Yes it was an upgrade from 0.7.0 done from within Minera.
The system was originally built on an existing card derived from NOOBS by doing a manual install from git hub.

Thanks for your time.
Nick.

pi@raspberrypi:~ $

It is a 1B, purchased April 2013

After running the above and "redis-cli del coins_profitability" the widgets are showing numbers again.
However the mining profitability table reads "No coins data available, please wait and try to refresh"
The Hourly charts also show "Ops! No data collected, wait at least 5 minutes to see the chart."

Argh! bugger, its now 15 minutes later and back the way it was - error in line 194

<p>Severity: Notice</p>
<p>Message:  json_decode(): integer overflow detected</p>
<p>Filename: models/util_model.php</p>
<p>Line Number: 194</p>

If I do "redis-cli del coins_profitability" the widgets work again, but everything between mining profitability and mining log is grayed out

Next auto refresh page is not working again.
 
Thank you very much for your help so far
Nick.

Nope - still get the error on line 194...

Thanks,
Nick.

Still the same error.

I'm now in the process of apt-get update & apt-get upgrade, 63 packages on the system need updating, I'll see if that fixes it.
Give it an hour or two...

Thanks,
Nick.

Used mineras inbuilt terminal to log in as pi sudo git pull changed 7 files.  refresh page didn't solve problem, sudo git pull again, everything up to date no changes, still not working.

My Minera 0.8.1 doesn't show any dash board data, all widgets are grey shaded with the hash rate showing as "calculating" and the bitcoin price as "getting data"
Clicking the raw stats button at top right then the "here" hyperlink, get the following -

<p>Severity: Notice</p>
<p>Message:  json_decode(): integer overflow detected</p>
<p>Filename: models/util_model.php</p>
<p>Line Number: 194</p>

I updated from 0.8.0 to 0.8.1 day before yesterday and the history charts are no longer recording data.
It also shows the "prohashing.com" pool as dead although Minera shows a non zero local rate and the pool is crediting my account.

Any pointers on what to do to fix without loosing all the previous data?
Actually just let me go check how much free space left on the card...

In the system load section, perhaps a free disk space indicator would be a nice feature...
 
Thanks,
Nick.

Nope - write protected, first thing the programming software asks to do is unlock the flash and erase the chip...

Hi - I've managed to destroy one of my g-blades in a manner that I can't easily repair.
I had them on a raspberry pi all powered by a battery / solar set up.
It looks like the power jack on one failed, opening the negative, causing the return current to flow through the RFI bead to the STM32f103 ARM controller ground, down the USB cables to the pi, through the pi ground and back to the solar controller ground.
The pi survived.
Along the way the ARM and 3.3V regulator were destroyed - as in escape of magic smoke and 3.3V shorted to ground.
There must have been over 5 V of drop on the ground there to reverse the polarity on the ARM and regulator to destroy them...
When I power up on 12V, I still have the 1.2 V rail, the 5V rail derived from the 12 V rail, and the 5x 3.3 v rails.
Fingers crossed the GC3355's are all ok. 
I've done some probing tracing of the board to understand how the GC3355's are connected to the ARM.  Looks like the only connects are to the ARM's 5 UARTs and some signals to the uP1509 that genrates the 1.2V

I think I'll replace all the 0 ohm links between the GC3355's and the ARM's UART ports with ~100 ohm resistors to limit the current that can flow into the inputs under fault conditions and put a schottky diode reverse biased  across the 3.3V rail so the power rails across the ARM can't become reversed.

I have a tech background and am able to replace the STM32f103RCT6 ARM controller, but I don't have any firmware for it.   
Back on page 29, I see there was a firmware image from" J4bberwock" but this is now a dead link.
Does any one have a copy of the g-blade firmware any more?
I am familiar with Atmel AVR / Arduino and PIC but have no prior ARM experience.
I'm assuming Gridseed shipped these with flash read protection active?
Surely its not as easy as reading out the flash from the good ARM on the other side of the brick into the programing software and writing it out again to the new blank controller?

Regards,
Nick.
