Hey nst6563,
what commands did you use to get both the summary and scrolling print out? I can only get one or the other..DOH!
Tanks!

Wolfey - here's the command I'm using. I didn't enter anything special that I know of to get both the summary at the top as well as the scrolling data.

Code:

minerd-gc3355.exe --gc3355=\\.\COM8,\\.\COM9,\\.\COM10 --gc3355-freq=\\.\COM8:1200:0,\\.\COM8:1150:1,\\.[b]\COM8:11750:2,[/b]\\.\COM8:600:3,\\.\COM8:1175:4,\\.\COM9:1225:0,\\.\COM9:1200:1,\\.\COM9:1225:2,\\.\COM9:1225:3,\\.\COM9:1225:4,\\.\COM10:1225:0,\\.\COM10:1275:1,\\.\COM10:1250:2,\\.\COM10:1250:3,\\.\COM10:1275:4 --gc3355-autotune --url=stratum+tcp://pool.manicminer.in:3333 --userpass user:pass

\COM8:11750:2,
Thanks. I'll chk it out. You sure about that? ^^^^^^^ I wish! Wink

@Happydaze - what you might try to check is the voltage on the vIN pins on the gc3355 chips. Test them all, ones that vary may lead to another clue as to where the fault is. Between looking at the board and the schematics you can likely trace back the supply voltage line and test at various points along the way to try and narrow down the possibilities.

Anyone know of a free dsn viewer? I can't open that file from the github docs.

I don't have access to my main computer, but I believe that I used this one for brd and dsn

re: only one chip working after volt mod attempt

I posted photos of the solder that came out from under a gridchip on my pod here: https://bitcointalksearch.org/topic/m.6432641 The cleanup went pretty good but still only one chip working after that. No mods, back to stock using the untouched 33k.

I tried to mine Bitcoin to see if that part of the chips worked and it mine for a few minutes and quit. I thought it was done for. It wouldn't mine anything after that. So I've been practicing my soldering on it and got it back mining on 1 chip using the stock resistor. I put a 47.5k resistor in the R52 spot like Wolfey does his 49.9k and to my surprise now chips 2, 3 & 4 are working ! ! ! I might end up with a 275+ kh/s pod.

Electrically, what is going on here? Why would two more chips start working by replacing the 33k resistor with a 47.5k? I had tried it again just minutes before changing that resistor and only one chip worked.

Any ideas to help me get the other two chips working?

What are your actual pool side stats vs the local indication thereof?
Is it coughing up accepts / valid shares on the right end? Wink

Your problem could be another 1 or couple or few compromised components. Check them against the specs', others tests on same etc. and see if you can narrow down where the other compromised part/s is/are.
Nice save! Shocked

Good luck! Grin

Hello Sandor111, great work you're doing.
I am curious as to why my seed speed hasn't calmed down to something more reasonable over the last ump-teen hours using autotune...They adjusted over several hours but settled at what seems to be their maximum-overkill setting which is yielding too high an Accepts to HW error ratio. Some just a hair under or over 10% and that's just too high! Way!
Do I have to manually guess and set them to lower speeds now after all that automatic tuning?
I sure love the autotune feature. I guess it still needs a bit of tweaking.
Let me know if you want me to take and send you a log file or not.
Thanks!
Wolfey2014

That looks Odd, I get a clean 510KH @ 1200Mhz and this is EXACTLY what shows in the pool... This is with Cgminer.. And I get <5HW Per 24Hr

wtf is Sandor? Sandy! Where are ya?
I don't much like the idea of being suckerd into being your guinea pig Tongue

I'm reverting back to your previous version due to the bug with autotune and HW error count being too high because all pods are being pushed over 1200MHz and held there, in this ver.
I love the simplicity of it though. I'd like to see output scrolling below simultaniously. I saw someone else had theirs set that way and mine wasn't (same ver) so I know it's not the default. Would it be --text=y ?
D-OH! I'm such a noob! Again! Grin

Please let me know when these two issues have been licked so I can upgrade again.
Thanks Sandor!

Confirmed it was a bad barrel plug with the multimeter. I guess it teaches me to test these things before using them...so sad...not a bad looking paperweight but still Sad

What exactly was wrong with the barrel plug? polarity reversed? intermittent / flaky power? I'm having a hard time imagining what could go wrong with the barrel plug to make it burn out like that...

I really don't know. Here is the series of events:

1. Newly wired PS (IBM 835w to 11 barrel plugs using 16AWG. This is the third one I have made.)
2. Not thinking to test by plugging in one miner at a time (like I did with the first two PS's) I wired up 10 pods to the PS and turned it on.
3. Spark bang smoke
4. Turned off the PS within 5 seconds. Think I was in shocked for a bit

5. Unplugged all the pods. Tried a different connector and PS to the damaged pod..nothing :/
6. Tried the bad barrel plug in another pod...started to spark and smoke but I quickly disconnected it. It still works although you can see some black charring on it. Guess I lucked out on this one.
7. Replaced the barrel plug with another one and plugged it into a working pod....worked!
8. Wired up the remaining 9 pods to the power supply and all are working.

Today at lunch I went home with the multimeter and used a known working PS and tested each barrel plug to see what voltage it was providing..they all came in at around 13-14v. It's a needle type multimeter so hard to say exactly. Unscrewed one of the known good barrel plugs and wired up the bad one. No reading on the connector end. Zero...tried to see if it was reverse polarity but still nothing. Pressed the probes onto the wires and it was good there...also good on the barrel plug screws.

So I'm not sure what the deal is.

Edit: If anyone with the skills to check would like the bad barrel plug to investigate let me know. I will ship it out USPS at my expense as long as your in the states.

Not necessary. The internal part of the barrel is obviously shorted out, perhaps via a caved in or pinched barrel or mis-soldering / mis-wiring and or it's just a defective part that got through QC without being picked up on. It happens.
From now on make darn sure you test all plugs and if needs be, jacks / receptacles with a DVM or the analog equivalent and use the 0 ohm or short test with beep when shorted so you know if it's open or short and verify voltage and polarity are correct with the proper meter setting. Yes it's DC not AC for you greenhorns Cheesy

I have 99 male coaxial power connectors with screw on type wire terminals and they allow for testing in or out of circuit. Nice!
I'll post pics of my new rig when she's all fired up and hashin in the cash! Wink

Woof! Woof!

Git and binaries have been updated.
TUI is included, and a number of bugs have been fixed.
A number of useful commands have been added, check --help for more info.
Win: https://www.dropbox.com/s/ttqa9p851siz8oi/minerd-gc3355.zip
Rpi: https://www.dropbox.com/s/xc3lvysi8vtrt00/minerd-gc3355

Hate to be a noob, but I downloaded the raspberrypi file, and now have it placed on my raspberrypi, what do i need to do to run it? when i try to execute the file I get:

(error while loading shared libraries: libjansson.so.4: cannot open shared object file: No such file or directory)

What are the installation steps for getting the Rpi file to run?

Answered my own question, posting here for reference.
was able to load the libjansson I needed by typing "apt-get install libjansson-dev"
then to get it working, instead of using COM ports, you need to use the following device strings from the /dev/serial/by-id/ directory
my resulting string afterwards as an example:
"./minerd/minerd-gc3355 --gc3355=/dev/serial/by-id/usb-STMicroelectronics_STM32_Virtual_COM_Port_6D83309A5750-if00,/dev/serial/by-id/usb-STMicroelectronics_STM32_Virtual_COM_Port_6D85446F5750-if00 -F 850 --url=stratum+tcp://xxx:4444 --userpass=xxx:xxx"

Ok Guys I have modded 19 Pods and Itest each one after I have done it.. Now got all 19 and I plugged them all in together for the first time after being successfully tested individually, anyway So I plugged them all in flicked the Powersupply switch and this is when I hear a small POP and flame like someone lit a match I INSTANTLY FREAKED OUT AND POWERED EVERYTHING OFF, OPENED THE POD in concern and this is what I see, I AM FURIOUS ANGRY as I HAVE TESTED EACH POD after I mod it and al worked perfect accepted shares NO HW and all perfect, but now that I plug the power in all of them I hear this POP and flames.

Please tell me what may have gone wrong here, Not enough power on the PSU cable? But not enuough power should NOT make this burn up and POP the moment I flicked he switch right? Anyway can someone PLEASE tell me the 2 chips I burnt I really would like to repair this pod... Its a waste, I am lost as to why this occured. I am using Acritc Mx-2 Compound- NON CONDUCtIvE so this could not have caused a short.

Please if someone can help me find these chips will be greatly appreciated.

HERE IS THE PICTURE OF THE 2 BURNED OUT CHIPS, THEY LOOK THE SAME SHAPE AND SIZE. IT WOULD BE GOOD IF THEY WERE THE SAME CHIPS.
https://www.dropbox.com/s/qymhbmgvu5raq1t/20140428_203015.jpg

If someone can also give me an idea how this may have happened, please remember I test each POD after I mod and wait for a few shares to be accepted before I screw it all back together and this went in flames the second i turned the power on ... I was thinking maybe I tightened it to tight and the copper heat sink touched something to short out? And no I have not used any copper shims yet.

I had this happen to me last night but it was due to what I think was a bad barrel plug. I replaced the barrel plug and it worked with the power supply on a different pod. My pod looks almost the same as your picture Sad

Borrowing a multimeter from work to try and figure out what was wrong with the barrel plug as I don't see why/how it would be bad.

Any ideas how this could happen? Haven't modded any of my pods but your post made me reply. I don't have the skills to repair it. If anyone would like to purchase my damaged pod please make me an offer Cry

Having the same issue with latest version as well, alot of HW errors due to autotune going too high in the MH/z, but it helps to see what the best
MH/z is for all my pods, some accept way higher as others

oh well looks like crystal swap is in the pipline - upgrade the crystal anyone? thinking maybe a 33mhz in there Wink

.

Since I'm curious, I ordered some crystals to test on one pod. I'll report if anything apart from black magic smoke comes out of the tests.
According to gridseed notes, the crystal used can be up to 50MHz.

Also, the miner in the output says it will adjust the voltage in steps of 25, ie " 2565 steps until frequency adjusts to 1175MHz" but then it really only bumps it down to 1190 from 1200 on the status display at the top. I can't tell what frequency it really adjusting it to.

Ok I'm retarded, the frequency adjusts per chip, so the readout is showing an aggregate of all the chips on the one particular gridseed device... my bad.

SAndor111 - how does your autoclocking feature work? is it keep increasing the frequnecy every x steps until hardware error? or is it an ratio % hardware error to accepted shares type thing. just wondering what the tech/ logic behind the auto tune is.
And a) recall how to compile for windows?? i was playing over the weekend but hit a wall!
b) any chance or mauall /via config file adjusting the autotune setup - to say x steps and x% hardware errors type thing???

i got one red nounce after several hours and it knocked the frequency back down. grr! one hardware error over several hours ainnt nothing, and its gonna be impossible for everyone to get zero hardware error - heck ive even had them on new grids at stock freq. each grid and each chip varys so much.
