UPDATE, small error found in previous v.99 upgrade. For anyone that has updated so far, please reapply the .bin found here:
https://github.com/GenTarkin/Titan/releases/tag/v.99

BTW, as of now the enable / disable lighttpd option under SYSTEM tab works =)

how long should it take when upgrading 2.00 ver??
I am looking for 2 hours at this line

System upgrade in progress
Copying files... files copied No wget found, syncing apt & installing wget Syncing apt-get...

Can I refresh a page or smth?

It should only take a good 5mins or so... Not 2 hrs unless ur inet is shit or your SD card is dead or ur inet is crap to the pi. If its hanging there that means apt-get is failing to sync & download wget. =(
If thats happening to a lot of installs, I may have to rethink the whole upgrade process.
All I can say is hit browser back button and try upgrading w/ the .bin file again.

This screen stays for an infinite time

internet is 6Mbit and SD 10class NEW one!

Bummer, do you only have 1 titan or more? If more then have you tested it on the others? Also, what method is the Pi hooked up to internet, wifi or eth?

[GenTarkin]

agreed, and I think you might be right. I found this. Its old but might have some helpful information. https://bitcointalk.org/index.php?topic=307055.0. So are you saying in the advanced page , the temps to the far right are the vrm temps? If thats true, and I think it might be, where are the temps of the 4 cores found, or do they average it on the status page? I think the next update might need clear labels on these numbers , as KNCminer gave us temps, but for what!!? Everything is not labeled in the miner, and its needs to be to clear up all of this confusion.

The pages are already correctly labeled LOL! DCDC = VRM's ... loosely interchanged to refer to the same thing.
The temperature column on the status page grabs those temps directly from a LM75 sensor... I dont know where this sensor is on the board, could u inspect the underside of the board perhaps? maybe there is 1 LM75 sensor mounted beneath the ASIC package. Its reading temps through the board, or maybe somehow the LM75 is integrated within the ASIC package.
But there has to be one LM75 sensor somewhere on these damn boards.
Either way, I suspect its an external sensor for the ASIC package. It functions to readout external package temps which are usually a good 10-30C less than actual die temps.

Out of curiousity how much did your temps change by when u slid the HSF around?
I have 2 theories,
1. when sliding HSF around this could potentially change airflow caused by your hand etc... and therefore the DCDC's were being cooled more or not depending on that airflow aversion.
2. If slid the HSF caused temperatures to skyrocket for a short period the dies may have went into a limp mode to avoid being blown up.

I suspect there is no on die temp sensor, otherwise we would see it being used. We arent.
Hey vegas, w/ ur thermal sensor thing, can you read temps from atop the base of the HSF while its hashing? Actually, if u could aim the laser at the package underneath the heatsink as its hashing, that would be really telling. If its close to the readout of TEMPERATURE on status page then the ASIC is using a single external package temp monitor. (thats already my suspicioun anyways, but it would prove the theory)
What I wish we knew was the TDELTA between the dies & the package temp sensor. If I knew what that DELTA was on average, I could code it into the firmware to reflect the correct average temp of the dies.

Just to add my 2 satoshis here. From what I've seen tinkering with these things is that the dies pull more power when they get hot. I had a couple of cubes damaged with the screw fixing at the back coming loose. Dies 1 and 2 would come on then the amps and watts of the DC/DC / VRM's would shoot up to 50 then the dies would go down/offline when watching the advanced page.

I took the heatsink off replaced the thermal paste then secured it back in place and the dies came back on as normal but no longer shot up in power or temperature. managed to get all but 1 die back and working, now its running stable with decent temps.

Ok I can run it with plate only and give a readout of what my temp gun says and what "temp" says on status screen. Ill let you know. If these are within 1C +/- I would like to see it reworded "average die temps" on status screen. There is no chips mounted under the pcb, Ill check the layout of the board, and post a screen shot too and see if we can locate it.

BTW, if more and more people experience issues w/ wget installing, then for the next release Im gonna go ahead and remove the upgarde button option located beneath my firmware version on status page. People will have to upgrade using .bin file method instead.

[GenTarkin]

Alright, found a way to actually download the file using curl despite the obscure URL which is why I had problems w/ curl previously. I will code up a new upgrade method and package and make a new incrimental release. Will do away w/ the questionable reliability of sync'ng apt and trying to install wget ... yay!

[vegasguy]

ok location of LM75:



close up of LM75 (you can hardly read it, I had to use a magnifying glass) :

[GenTarkin]

HAHA! Figures, well it must have a remote temp sensor somewhere. Would have to trace the traces... which being a multilayer is impossible.
I bet the sensor is somewhere or in the actual ASIC package.

It would be super retarded if KNC just put that there and the sensor was close but all it did was measure ambient, lol Id wanna burn their farm down then, oh wait I already want to...

A schematic might help.

Announcing new firmware v.99a:
Quick, incremental fix for failed installs when hanging on wget installation(apt-get syncing etc...)
No longer relys on wget being installed to download files when using STATUS->upgrade.

https://github.com/GenTarkin/Titan/releases/tag/v.99a

[frenchy]

Hey vegas and gentarkin ,you have a lm75 on the controller board too!!!just take a look between the lcd display and the Rpi...

[GenTarkin]

UPDATE, small error found in previous v.99 upgrade. For anyone that has updated so far, please reapply the .bin found here:

Please attempt installing the new released v.99a firmware .bin file here:
https://github.com/GenTarkin/Titan/releases/tag/v.99a

It wont attempt to install wget anymore, should have no problems with this release.
Upgrade should finish in a few mins.

Rofl really?! well I dont think thats being polled for any info as per the webgui at least.
If it is then I have no idea wtf is going on =P

Is the LM75 the actual temp sensor itself as well? if it is then measuring the temperature on that location of the board is purely a freaking ambient temp - "inside of the cube" temp ROFL! Thats quite useless, thanks KNC.

But if it uses a remote temp line then where that remote temp thingy is... is a mystery, I would think somewhere near the ASIC package.

Whats funny is, if the LM75 itself is the thermometer and the DCDC's temps are just really the DCDC temps then ... we have NO fucking clue what the actual ASIC die temps are =P    ..... engineering at its finest....

[GenTarkin]

Hey vegas are one of these on the hashing board? tps65217

I would think thats for the FPGA but double check.

[frenchy]

[/s]I believe the tps 65217a was located on u16 on your last picture vegasthe eight chip near the lm 75.

[vegasguy]

I believe the tps 65217a was located on u16 on your last picture vegasthe eight chip near the lm 75.

I found this and it sounds like its on the controller :

https://github.com/KnCMiner/knc-asic/issues/2

[frenchy]

Maybe under the lcd screen  on the controller?

[frenchy]

No it was on top of the molex connector on the controller.

Interesting, will the titan refuse to mine / power up if the LCD is not there rofl?!
Or tps65217 for that matter?
