Hi all, I recently formatted my RPI SD card and lost the firmware for the miner, should have backed up.
I've tried different versions, although non work. The screen comes on, shows false default IP. and constant flashing green LED's.
I had plugged the RPI in backwards and turned off/on/off/on repetitively. But I've done this before and had no issue what so ever, the Raspberry PI functions as normal so no shorts, while the screen side of the Miner still works. Moving along, can anyone link me or send me the miner .iso for the Raspberry Pi Please. I'm in great need for it as I have someone coming to collect it tomorrow at 11:30Am.

Many thanks! 

It's been a while since I have used it (i believe it is 192.168.1.179 but that could be wrong).  https://www.dropbox.com/s/yz02suc4j24ium4/dragonboot-4BLADE-ENG.7z?dl=0

It is 4 blade with screen dragon.

Yep, the default ip on the one I tried was 192.168.1.134
Link not found :/

Appears it's no longer in my dropbox.  I no longer have the 1T dragon if someone who downloaded my image wants to upload it they are more then welcome to.  Appears I just have the 1.5T image in my files.

You might try this one i know it's modified a little - https://bitcointalk.org/index.php?topic=523634.msg8228012#msg8228012

Thank you, I'll give that a go

I'm starting to think the Raspberry PI is faulty, or either the SD card, reason being. I noticed that the miner shows the screen and details even without the raspberry PI plugged in, was quite shocked at this. Tried booting via wheezy on my monitor, nothing happening. Power is fine, fuses all fine, now to check if ACT lights up fully. If not I'll resort to another SD card ._.

Nope checked SD Card, all fine. And boots up with any Dragon image and I can see it on my external monitor. How ever what I think is happening is it's not connecting to the internet, it keeps pining 4 single numbers saying its an ip.
While it also gives out the default ip yet I can't connect, on other raspberry PI images I can connect to the internet, just not the dragon image.

Is there anyone who could reupload this image? Dropbox link is dead atm.

Thanks in advance.

Dropbox link will remain dead sadly.  I tried to find a backup to upload and I do not have it, and don't have the 1T dragon anymore to copy it.

There were a few different images people have posted.   Hopefully someone will have a link  to one of those for you.

Try that one. It should still be working. I uploaded it a while ago.

I've got:

dragon-with-red-box-ip-192.168.178.73

stuck away on a NAS that I can upload if necessary.  Just let me know if no one has one posted.

i am still running the 4 board 1 ths models.. if you need a firmware i can make one fresh tomorrow and get it uploaded for you..

Best Regards

Same here

It would be great if anyone could do a fresh copy of firmware...

Do you know is it one with default ssh password or one with altered?

Thanks

Will give it a try tomorrow.

Thanks.

I try this FW, but seems it has no autostart on my miner. Can anybody help me?

This is the firmware that doesn't allow SSH.

hi there,

is there any image with an ip adress like 192.168.2.xxx or how can i change that in an existing image before i put it on a sd card

I think you could change it if you mount in linux, I have not tried it to see if it works.  But you would be able to edit the file.

Easiest would set computer or 2nd router to IP range log into miner and change it.   Make sure to make a backup of your SD card before doing it.  But that is a odd IP range doubt anyone has a image ready for it.

Easiest approach would be to direct ethernet to your laptop/computer.  Switch laptop/computer to same network and then web into the dragon and change in the gui to what network you want.

how would i do this with a computer, my isp wont let me change my range it is 192.168.2.xxx can change it

You might call up ISP tell them the router is causing troubles and you want "bridged" mode.  This allows you to have your router instead of their all in one.

But plug ethernet cable from dragon into computer's ethernet.  Configure them on same IP range.  Then go to machine and change it to proper settings.

Make sure to make a backup of your SD card before trying any of this.

al sorted out, thx for the help.

one last question,
I can set the difficulty in thr gui of the miner, what does it need to be for example f2 pool.
if i look at my dashboard at f2 it does not reach 1 th/s

greetings

It does not matter what you set it to for most pools.   It will automatically pick difficulty based on your speed connected to pool.

So yea set it to 256 or something.  But you will be fine it does not matter.   Also might look into antpool it has PPS at 2.5 percent vs f2pool 4 percent.

Set it to at least half the speed that you've seen it hash (or what it is rated to hash) to be on the safe side, i.e if you see 1Th/s, set it at 512 and the pool will take it from there; that way you avoid the classic S2 syndrome!

thx for the reply all off you, s2 syndrome what is that

If the diff is set low, then the software on the rig may get into a loop (for lack of a better word) trying to submit so many shares in a very short space of time that it crashes the rig before the pool has a chance of adjusting share diff. I personally always set my rigs' diffs higher than their rated speed (as I know the pools I mine on will lower / set it appropriately after a while).

I have used the dragon 1T and 1.5T.  Really 256-512 it does not make much of a difference.

Once you connect to a decent pool it automatically adjusts the difficulty.  The dragons are pretty much set and forget if using a good pool.   They seem to have a very long lifespan (minus the PSU's used in them).

^^^^ And that is the plague of signature campaigns striking .... basically nothing to add to (not even negate)  what has already been said.

I appolgize if it was worded wrong.  I have used many dragon 1t A1's and not experienced the "s2 syndrom".  I was negating that setting a 1T dragon to 512 really making much of a difference.

I believe the default is 256, and it has no issues at this.   So I was meaning to negate your statement of 1T dragons having as you call it "s2 syndrom"

Hopefully that clears it up.  Pekatete have you owned a Dragon 1T?
