Will there be a new groupbuy going soon? I'm very eager to get in on the batch that won't have these problems people are describing here, as I in no way know about tampering with the software and stuff like that.

Has anyone tried the new firmware at this point?  I downloaded it, installed it onto a spare flash card, but my miner has been running stable for the last 24 hours so I haven't felt compelled to mess with it.  I was wondering if anyone had tried the software and seen improvement.  Thanks.

I was going to wait and mess around with the firmware tonight, but decided to just do it and see what happens.  Loaded up 1.0.2 and right out of the gate the system on boot up decided to drop a card.  I let it run and watched the hash rate fall on the failing card which took about 10-11minutes to get to the place it decided to reboot.  When it got down to about 15mh on that card the miner rebooted itself and started hashing again normally.  I am just monitoring now to see how long it will run before it decides to reboot itself again.

I am still on Litecoinpool at this time due to stability of a single coin being mined.  Not a good sign that the miner dropped a card almost immediately.  But it is a good sign that as the hash rate dropped it did eventually detect it and restarted the miner.  So possibly some progress in getting the miner back up when a card stops hashing.  

On the hashing front, the miner side says roughly 270, but the pool is reporting only in the 230's and lower end 240's.  So still not hashing at a very good rate.  On the settings front the new firmware came set at 815mv and 1200mhz.

So how are the A4's going? If someone wants to send me one to test/troubleshoot/take apart let me know.

Well the A4's need some firmware help for sure.  They are going to open source the software so we may be able to get our code experts to take a look at this.l  I know there were some folks who did A2 firmware, and I don't know if GenTarkin would want to play with this or not.  The tough part is getting one in the hands of the guys who can massage this and make it work better.

If we could find someone that knows what there doing and we can trust. Maybe we could start a fund pool to buy them one unit in exchange they fix it and the miner could be there payment.. Just a idea

Hm. Is the source controller computer a beaglebone black? I have a few of those over here and can fire it up to see what it does.

If they're having code problems they should just drop ship a single unit to Tarkin or something. The $600 or whatever cost is miniscule to the value of having more eyes on the problems.

So it appears the v1.0.2 rebooted again on me.  Not sure what precipitated it as I was out running errands when it happened.  So it does not appear the newer firmware fixes problems with the need to restart.  At least if it is due to a hung card it appears to be trying to keep the miner alive at least.  But stable? Nope not from what I am seeing.

Thats what worries me most either dealing with poor coding skills or inherent hardware design flaw.

So it appears the v1.0.2 rebooted again on me.  Not sure what precipitated it as I was out running errands when it happened.  So it does not appear the newer firmware fixes problems with the need to restart.  At least if it is due to a hung card it appears to be trying to keep the miner alive at least.  But stable? Nope not from what I am seeing.

Confirmed here too, 1.0.2 does not fix the problem for me, if anything my experience is worse on this build than the build I was running. 1 card went down after only a few hours.

I noticed that the miner was most stable for me when I set starting difficulty at 8... 1.0.2 was built with 8192 as diff setting but still showing 8 as default. After I stopped the miner in an attempt to get the missing card to come back online, it would not restart.

I checked all my settings and changed the starting difficulty back to 8 and it came up.

Don't know if this will have an effect for anyone else or if it was just dumb luck.

On a side note, I feel like 1.0.2 hashes just slightly lower than the version I was previously using (I think it was 1.0.1)

No doubt in my mind that v1.0.2 is a fraction slower.  still have blades dropping though. Not sure what this version was suppose to fix.
Fortunately, im running them on a switched pdu, so I can power cycle them from anywhere.

I'm seeing the same thing with my Batch 2 miners. These are the miners with the controller software with V1.0.1 beneath the LTC LIMITED--T SERIES and can run the V1.0.2 image Chloe posted. The Batch 1 miners I have run rock solid with the 1.0.0 firmware (just says LTC LIMITED--T SERIES with no version number beneath). The hardware is different in some way. A B2 image will not run on a B1 miner. Hashrate = 0

If you're not sure what you have or mixed them up like I did, you can find the manufacturing date on the tamper proof sticker which is covering one of the rear case screws. Batch 1 machines were made before 15th Oct.

At the moment I can't keep a batch 2 machine with the new V 1.0.2 firmware running for longer than about 30 minutes before it restarts itself. I'm glad to hear that Inno will open source the firmware. It would be good to see Gen Tarkin or Emdje work on improving it.

I'd happily sponsor it with a few Satoshis.

 There were 2 folks that wrote A2 software upgrades (This is NOT Firmware, it's SOFTware).

 I'm sure one or both will be looking at A4 software "fixes" as soon as they get an A4.

Well 1.0.2 is less stable for me than the version I was running previously.

When the miner drops a card, it absolutely will not restart on 16384 starting difficulty, if I change it to 8, it starts right up.

I'm still doing some testing but I think I'm going back to the previous version unless I am able to find some stability.

At least on the previous version it would at least run like 2 days before a card would drop.

I have 3 running miners. Each of them drops 1 or 2 cards at least once per day.
Fortunately, I have a switched PDU which allows me to power cycle remotely.
I need to "automate" that somehow, because I don't catch the drops when they happen, only if I go look at the miner.
Im running the G5-1102 version.

I have switched back to older build.

Apparently I was wrong about 1.0.2 being slower, I switched back to 1.0.0T and it was slower 6 minutes in. I tried to take a 2nd picture of 1.0.2 at about 25 minutes but it crashed right in front of me while I was attempting to screen cap. EDIT: I found on another site that someone said 1.0.2 restarts around 22 minutes -- this corroborates what I experienced.

I believe I have a Batch 1 based upon posts I found else where and the fact i have the 1.0.0T version.



1.0.2 Screen capture from previous post



1.0.2 @ ~6 Minutes -- Hashing around 272MH


1.0.0T @ ~6 Minutes -- Hashing around 267MH


At this point, I'll trade speed for (more) stability between the 2 unstable versions I have.
