on mini image i could start cgminer thru putty and file with command.
but 4.0 version isnt working.
when starting file nothing happens.
and i cant copy paste command to putty as it starts cgminer in middle of pasting. anyway to start miner using ssh?
Cgminer starts automatically, no need to start is manually. Just put in the right info in the webinterface. If you do want to start it manually you need to disable auto startup. The problem I encountered with starting trough putty is that once you disconnect, cgminer stops. EDIT: I now read you say 'mini image'. Problem with that image is that I can't check what happens with that one. I have no new A2 boards to check my work, that is why it says experimental. About the sha256 reference in your picture. That is just a reminiscence in the code from when it was first used for the A1. I fixed most references in the output, but missed this one. Will fix that in the next release (which will take a while, have been busy with submitting paper for review). |

At 8 kh/s I assume you are mining with your cpu?
I would advice to stop mining, it is a waist of your power.
If it is a work computer I would recommend mining something else with your cpu.
You can use cpuminer-multi-rel1.0.9 to mine many algorithms, I use cpu to mine Lyra2RE.
The core i5-4590 I am on right now does about 610kh/s.
Other algorithms might even be better to mine with CPU, but this is what I use.

You are welcome. And great to hear my image works well.
If you do change out the psu be aware of the polarity of the connectors to the board. I had to switch the pluses and minis-us of my computer psu for the correct polarity. Measure and check the polarity!!
|
|
|
|
would psu cause this?
had to lower three blades to 1100 and three left at 1280 giving me 88mh/s with 3.8% hw errors so not bad
Well yes, if the power supply can't provide enough/stable power it could. |
|
|
|
temp in room about 25-28 celcius. a2 mini was getting around 2% errors
Which software is on there? Because the way the deviders are set-up in the firmware matters quite a lot to the amound of hardware errors. I would recommend my latest version. |
|
|
|
|
1280MHz in normal configuration should be around 6% errors or something. 1200 should be low low enough. Indeed how hot is your room, they work alot better when the chips are colder, < 50 Degrees Celcius.

Great development so far, I am watching  |

.......
Parameters are:
8MB cap
Doubling every two years (so 16MB in 2018)
For twenty years
....
Does that mean in 20 years after it starts doubling the blocks will be 8192 MB, which is 8.192 GB per block? Have I done my maths right? 8 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 = 8192 To keep it simple I'm not considering the difference between mebibytes and megabytes. Yes but 20 years ago we had this:  The computers now are not comparable with the one from 20 years ago, unthinkable even. And the computers from 20 years in the future will be unthinkably fast as well, so I guess blocks of 8.2 gb will not be a problem. |

I'm having pool issues again.
I usually connect through miningrigrentals. My gridseed rigs connect fine (via stratehm proxy), the last few days, my a2 has had trouble using mrr. It currently can't connect, although it can ping mrr ping. I've tried adding --failover-only but it's not helping. As my last pool (I hacked it to have 6 instead of two groups of 3) I have clevermining, which it usually, but not always, will connect to. I don't have a brilliant connection, but it's generally ok for mining.
Weird I never had any issues with any of the versions (only with the latest one I use personally over wifi and have not released due to those issues). Now that I come to think about that, do you use ethernet of wifi? I will finalize as you can read an new version soon. I will revert back to the old stratum code, because I think that is a little bit flaky. |

Hi Emdje, Would it be possible for you to upload the latest image with 1200-1220-1240-1260-1280-1300-1320-1340-1360-1380-1400 available? I am working on it right now. I can't finalize it because I am not at home, but it will come soon. |

You could sell the PI and buy some coins  Would generate the most coins I think  Or you could host a simple peer to peer mining pool at a 1% rate or something |
|
|
|
I'm pretty happy about miningrigrentals myself. If you pick a seller with a good rating, he'll most likely provide you with the necassary power... Also, if they try to rip you off, i think miningrigrentals refunds your money...
Miningrigrentals indeed refunds fully or partially if anything is out of order. |

I can't find a watchdog, no sign of cgminer getting restarted.
I've got my own watchdog running now.
Other than stopping, possibly when trying to start when servers aren't responding quickly enough, your image has worked ok.
I had a quick go at putting your cgminer in minera. It didn't seem to like the mix of command line and json.conf. I can't be bothered to delve into minera...
The watchdog is programmed into cgminer, it is not external: /* Makes sure the hashmeter keeps going even if mining threads stall, updates
* the screen at regular intervals, and restarts threads if they appear to have
* died. */
#define WATCHDOG_INTERVAL 2
#define WATCHDOG_SICK_TIME 120
#define WATCHDOG_DEAD_TIME 600
#define WATCHDOG_SICK_COUNT (WATCHDOG_SICK_TIME/WATCHDOG_INTERVAL)
#define WATCHDOG_DEAD_COUNT (WATCHDOG_DEAD_TIME/WATCHDOG_INTERVAL)
static void *watchdog_thread(void __maybe_unused *userdata)
{
const unsigned int interval = WATCHDOG_INTERVAL;
struct timeval zero_tv;
pthread_setcanceltype(PTHREAD_CANCEL_ASYNCHRONOUS, NULL);
RenameThread("watchdog");
set_lowprio();
memset(&zero_tv, 0, sizeof(struct timeval));
cgtime(&rotate_tv);
while (1) {
int i;
struct timeval now;
sleep(interval);
discard_stale();
hashmeter(-1, &zero_tv, 0); The big problem was that cgminer exits if it can't connect to pools. It does seem to keep running if it starts properly. I've got a bash script that checks for the right number of ./cgminer processes every 3 minutes now. Too many, it kills them all, not enough, it invokes run.sh. I had some gridseed rigs where they sometimes started duplicate copies of cpuminer, which doesn't work very well. Your firmware hasn't had that problem, but I've left it in. edit index.php to change run.sh to check.sh check.sh, stick it in /var/www #!/bin/bash while true do MC=$(ps -ef | grep -v grep | grep -c "./cgminer -o stratum+tcp" ) # echo $MC if [ $MC -lt 2 ]; then sudo ./run.sh else if [ $MC -gt 2 ]; then # echo too many sudo /usr/bin/killall -s9 cgminer fi fi sleep 180 done Thnx I'll check it out |

So what command should i use for cgminer?
Psu was replaced on this one. Came with hp server psu
I don't know what is A2 command set. But the one you put is A1 setting. Maybe you can post miner & setting page. The software that Innosilicon used for the A2 is basically the same as they used for the A1. They just forgot to change all instances of A1 to A2, firmware is for A2 and should work. But as Wolverine5pl stated in a different topic, his blades are working now, were loose resistors due to transport: https://bitcointalk.org/index.php?topic=672969.msg11513791#msg11513791 |

how to start cgminer from ssh on image for a2 mini? i need to reboot my miner everytime i want to change pool  nvm found it:) for some reason wasnt starting. just need to install screen and Im good to go. thanks for great image. scripta was crap. most of times cgminer woudnt start:/ Great to hear it works. And great that you could fix the transport damage. |

 only blue light and one light on side of plate on top of blade. about logs. tried your image but wasnt lucky. on image that was installed was reporting no device. If you look closely on the blades you will see LED's that are marked LED_UA4 - LED_UA3 ...... to LED_UB1. These LED's indicate if the chip is properly working. When blinking they are noticed by the software but not running yet, when they are not blinking they are hashing and when they are off there not working. after closer examination I found lose resistor in chasis. after soldering it back on small board blades came back to life:) thanks for help guys Great to hear that it is working again! But where did you buy these broken blades? |

I've had a rummage, your image is infinitely simpler than minereu or even scripta, whoopsie. I've set it to append logs to cgminer.log so it does more than one session and had a nose around. If it can't connect to servers on starting, cgminer exits. It doesn't seem to retry, at least not very often. this is not good for those of us with flaky internet, is there no watchdog? I can't find one, but may be looking in the wrong place. I thought there was a swiitch to stop cgminer exiting, but can't find it, maybe it's just cpuminer. I wrote a crude watchdog for my rigs two years back, I should be able to find it, somewhere. I haven't got it to duplicate the no A2 miners found error today. I'm currently cloning minera to see if I can get that to play ball, I have it running sweetly on my gridseed blades. It might be worth you collaborating with Michelle if I fail. I tried to get cgminer to run on my gridseeds last year, but failed. log from this morning, while both connections was down (it's fun out here in the sticks). It exited repeatedly the same way a weekish back when it did have a live connection, possibly servers were sluggish? Both main and secondary connections pinged ok to google DNS that time. My other rigs were showing as hashing on the pool site. The only thing I've done to your image since last week is change '> cgminer.log' to '>> cgminer.log' in index.php and run.sh it's running now... [2015-04-19 17:21:52] Started cgminer 3.9.0

Yes there is a watchdog, but it seems that more people have troubles with version 4. I will revert back to the old stratum code, because I think that is the troublemaker. I have time tomorrow to fix that, and will post the binary as well as the complete image. |
