Topic: Efudd Z-Series Fuddware 2.3 -Z11/Z11e/Z11j/Z9/Mini - page 21. (Read 45527 times)

Try the stock firmware and see how it works and let me know. I have a couple of ideas, one of which chipless mentioned above.

Thank you,

Today Kernel Log from my Z9 Mini:

Something particular happened,

In my effort to find a solution to: "Socket connect failed: Connection refused"

I tried connecting to the control board 1 Hashboard at a time (1,2 or 3), then 2 Hashboards at a time (1-2, 2-3, 1-3), and finally the three hashboards, after all the tests it is only starting with 1 Hashboard connected, it does not matter if it is 1 or 2 or 3). "always connect with 1 Hashboard", without the error message: Socket connect failed: Connection refused. but it's just "1" Hashboard connected.

hello...startet today with 2 used Z9 mini and just wondering - which static diff is recommended atm for ZEN?

I had a similar issue with antpool when setting my miner up make sure you have  statum+tcp:// as part of the server when you type it in the miner. I don't know why the miner sometimes will detect it and other times you have to make sure it has what I posted added to the server in the miner configuration. That's what it took to fix it for me. You can see the difference in your log one that is alive has it the last one don't causing a wrong url

Thank you for your answer,

I leave the Kernel Log of January 6 when the Z9 Mini was reinitialized repeatedly and displaying the message "Socket connect failed: Connection refused"
(The problem has continued randomly until today)

That message is normal and exists until cgminer in the firmware starts up AND properly connects to a pool.

To understand what is going on with your system, I would need to see the logs when it happens.

I have an issue with my Z9 Mini (Original Bitmain Firmware, all my hashboards tested one by one and are Ok!), When the miner lost connection for any reason and tries to reconnect to the pool, the system shows: Socket connect failed: socket refused!, power off for some minutes and power on again solve the problem, but this can be made some times in a day. The Efudd's Z9 Mini Firmware can fix that issue?.

Thanks.

Cool deal. Good troubleshooting and I’m glad it worked out.

-j

I added more miners and swapping them around for better cooling but will get some log data for you within the next few days. Kind of weird how the temps show ok but yet is still throttles back for a few minutes then goes back to full speed.


Jason I found the problem it was a bad pigtail on a power adapter heating up causing the board to drop and come back. Fixed it.
Thanks for offering to look at it.

I'd have to see the logs to guess, to be honest. There could be a couple of explanations.

-j

Gotcha… I like to play with this stuff and am sorry I didn't pm instead.


One last question when I run my Z9 up to or higher then 700m I don't get any x errors but after a few hours the machine seems to throttle slowly 1 or 2 boards back down to a 0 k/sol and sits like that for a little bit then will throttle slowly back up to the full speed. The temps are showing fine usually board tmp in the 40-50 range and the chip tmp around 60-63 it don't matter what fw I use the result is the same.

So the question is do you have any idea what this could be or is it just overclocked too much causing this. I can lower back down to about 668 and it goes away and never throttles the board.

I'm not sure you got what I'm saying. What you'll notice most about my posts are me explaining what I don't know, not what I do know instead of a 'look at me, here is what i used to do!'.

As far as gear goes, Yeah, I have a lot of gear I don't know how to use properly, too. One might would think I were an EE if they saw my home lab. I have plenty of test boards, data loggers, FPGAs, oscilloscopes, function generators, programmable power supplies, soldering irons, desoldering stations (yeah, plural on all of these for some reason), programming boards for random chips, serial interfaces for anything you can think of, beagleboards, raspi's, blah, blah, blah. (I have a dozen of these for some reason; probably unfinished projects I can't remember pre-coffee).  I don't have a pick-n-place, though. :-) .... None of that makes me experienced with this device nor reverse engineering.

Every bit of the work I've done on this has been done on a raspberry pi, actually, after the initial hardware evaluations.... I temporarily decommissioned my HAM Radio hotspot for this project.

BTW, I recommend a 'jtagulator' if you like trying to crack hardware open and aren't always sure which pins are JTAG.

The reason the fan controls are not "accessible" directly as a function pointer is that the fan control function in cgminer is compiled "static inline". That means the function is written separately, but is effectively just part of another function (as if it were never a function by itself) when compiled. It is an optimization, among other things.

My point simply is if you'd like to guess about something, leave it in a PM OR have the awareness to make it very clear the difference in what you know and what you suppose so readers are not lead astray.

-j

I understand what your saying....The code I am use to looking at uses jmp and other commands. There is a difference between the language disassembly's but yet they can be similar. Coding for Dallas Micro's and AVR's was similar but different and a PIC different, many of them I was working the othr way though not backwards thru a bunch of mess. I definitely have the equipment to interface directly. I have jtags, hardware emulators, programmers and a few other tools even a couple of Rasberry Pi 2's around. I have a couple of test boards I designed for AVR's that you can setup to control ,log, or whatever else whatever.

Thanks for the feedback

Just wanted to pop on here to say OP is a legit dev, and I'm really happy with his FW on my z9 mini.  So if you are on the fence, just make the plunge and don't look back.

Oh, if you are looking at cgminer in your statement of "they just took away the jmp into it", then you just don't understand software or compilers in that comment.

I suggest you look at what "static inline" does when something is compiled (google it. seriously. then write some code, disassemble it, and understand what it does) before making the comment you made. That is what you are referring to, but don't yet realize it.

As far as the rest of cgminer goes, bitmain modifies cgminer slightly to support hardware. They build with a set of options, lots of stagnant code is left as a result.

Bitmain doesn't have the clue to "take away a jmp". Their OS design is horrible. Their web interface is horrible. Their OS integration is horrible. Their scripting is horrible. Their code is pathetic. I don't mean how things "look", I mean how they are implemented. It is very clear to me that they don't know what they are doing and they cobble things together at best. If their hardware design is similar (I don't have the experience to comment on that yet), then they are not long for this market no matter the name they have.

The only code in cgminer that's worth a darn is the code bitmain didn't contribute.

If you are still trying to figure out how to control the hardware through their cgminer, you are wasting your time. Instead, go map out the pins on the ZYNQ, and then read up on the /proc interface until you become aware of how to expose additional gpio's to the linux subsystem. Once you map the gpios from the ZYNQ to the downstream hardware components (PIC, i2c, etc.), THEN you can make progress.

The OS and hardware are mailboxing the hardware control calls over the memory mapped axi regions. That's why you don't see it in the OS directly. If you don't understand 'mailboxing', search for 'mailbox software concept' -- it's akin to (but not scalable) message queues in concept.

Honestly. That's the way. That's the secret. That's the work I'm not doing at the moment because mapping out 191 pins for little return is not in my game plan. If you want to use that as a learning exercise, go ahead.

I agree a lot of junk leftover. Some of it is interesting though how they left part there and just took away the jmp to it. I noticed some weird stuff on the fan control.

No.

I wouldn't "gather too much" from the existence of that check. There is a significant quantity of legacy crap in bitmain's scripts and it wouldn't surprise me one bit if that was not left over from some previous PIC they used as a live or at-factory or in QA/dev ability to update the PICs firmware if needed.

If you want the PIC firmware, pull it from the PIC itself.

Jason

Have you come across a pic.txt file in any of the images? From what I am gathering it is the update file for the pic on the hashboard.
Normally cgminer looks for it in the /sbin  folder

I am wondering if this is how the different revisions are limited to speed. If the pic chip code was changed. I would like a dump of each board revision to compare. I do see it is possible to dump the pic with cgminer

I see, many thanks for the reply, appreciate you coming back to me.

I've updated as per your instructions and it's all sorted.  Really like the per board control.

keep up the great work 

jamiec, you are mixing up the firmware upgrade from the license application -- and the confusion is my fault. When I first provided download links to paid users, it was the whole firmware. The updated links are just the license file.

So.. apply 2.1d, CLEAR YOUR BROWSER CACHE, then follow the instructions in your "UNZIP_ME_*" file.

PM me if you have any other questions.
