Change log for version 2.1c and d:
- Corrects a condition where the wrong pool was sometimes being returned to after the dev-fee cycle.
- Added frequency tuning guide to "Miner Configuration -> Advanced Settings" page; If you do not see this, please clear your browser cache.
- Updated the frequency selection list up to 850; this corrects an oversight for the Mini releases and allows you wild and crazy kids to try extreme (but not recommended by me!) frequencies.
- Resolved a race condition where multiple cgminer processes could start running after setting new frequencies; I'm 99% confident this is resolved now.
- Corrects an issue where certificates expired after 30 days resulting in a failure to mine properly; paid license users will need to re-apply their license after upgrading. This is a mandatory upgrade as 2.1(c) and earlier will stop working because of the early expiration mistake.
The majority of issues seen are related to stale cache in webbrowsers. I will fix this in my next release. If you are not seeing what you expect after upgrading, please clear your browser cache and try again. This will be true if you upgrade or downgrade.
If your browser automatically uncompresses archives, you will get a 'tar: short file read' error on upload. Please disable automatic uncompress in your browser. You should be uploading a ".tar.gz" file to your miner, not a ".tar" when flashing the firmware image.
Paid users - please use your normal download link for instructions.
I am proud to announce the release of version 2.1, built on top of the reliable 1.x releases which have a proven track record of success and is installed on more than a thousand+ machines! This has taken me a lot longer than I expected to prepare and release, but I am confident in the development, testing, and the resulting product. I welcome feedback and will address responses, questions, etc. as quickly as I can.
This includes all of the functionality of the previous release (stable overclock, fully unlocked, proper temperature/sensor measurements, etc.) and brings a framework for adding additional features and a much requested feature to control the frequency of each hash board separately. In addition, the frequency selections have been updated to support the broadest range of frequencies.
To tune for best frequency
1) Set global frequency to 650. Set each other frequency to "Use Global".
2) Observe your boards for at least 10 minutes, if any drop out, on the next cycle decrease their frequency by 1 step in the pulldown.
3) Repeat this cycle until you have a stable minimum frequency for your boards.
4) To start the 'upwards tuning', choose one board (#1 for example) and increase it's frequency by 1 step.
5) Observe the board for at least 10 minutes to see if it is stable. If it is, repeat #4. If it is not, drop down 1 step and move to the next board.
Going through this process (which hopefully makes sense), you should be able to tune your units for your individual system maximums. It's best to do this with the fans set to 100% so you can remove thermals from the equation -- after which, set the fans back however you want them and see if your boards stay stable. If they do, good, of they don't, eithee decrease freqeuncy by 1 step or increase fan.
Please do note that sometimes a lower frequency produces a higher hash rate, so be mindful of that as you select for your environment.
Version History:- Version 2.0 - Initial release with individual hashboard overclocking
- Version 2.0b - Corrected a minor issue with the reporting of frequencies in the web interface after a reboot.
- Version 2.0c - Corrected an issue with the "dev fee" running too often. This is a recommended upgrade for all users.
- Version 2.0d - Corrected an issue where if pool 0 was dead, the dev fee would not return to the previous pool. I believe this is now completely resolved.
- Version 2.1 - First release available for Z9 and Mini users as well as paid and dev-fee users.
- Version 2.1c - Expands frequency options, resolved cgminer restart race condition, adds tuning guide, corrects issue where the wrong pool was selected after the dev cycle in certain conditions.
- Version 2.1d - Corrects an issue where certificates expired after 30 days resulting in a failure to mine properly; paid license users will need to re-apply their license after upgrading. This is a mandatory upgrade as 2.1(c) and earlier will stop working because of the early expiration mistake.

Example of 3 boards running at 3 separate frequencies.![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FR3eSJrX.png&t=665&c=t2-H99sJJJJNTQ)
In the near future I will be adding support for fan/temperature control curves, voltage management(TBD), automatic overclocking capabilities through heuristics to evaluate your individual board performance, and much more. I have a pipeline full of ideas that can be applied to the Z series and other miners alike.
Please note that this firmware is "free", but does include a small developer fee consisting of 10 minutes of developer mining time for every 280 minutes of regular mining. The exception to this is when the miner is first started, it will mine for the user for 10 minutes, and then developer for 10, at which point it will cycle 280minutes user, 10 minutes developer.This has been changed to 3% dev fee -- 10 minutes for dev, 320 minutes for you as of 12/7/2018 00:00:00 GMT.
The first time the software is started, the hashboard frequency page will not have any items selected. Choose "Use Global" or any other frequency and apply; the selection will stay for future changes.
This is not a source-based modification, but instead was performed using an ARM disassembly, some sweat, tears, an oscilloscope, and other misc. equipment.
If anyone cares, here is a summary of the kind of work that has gone into this. Not all of this is original code, but a significant portion of it is.

To install the firmware:1) Download the firmware from the link above, do not uncompress it, leave it as is.
2) On your Z series unit go to System -> Upgrade -> "Flash new firmware image"
3) Use the "Choose file" dialogue and select the file you downloaded in #1.
4) Select the "Flash image" button. You can use or disable "Keep Settings" at your own preference.
5) You will see the image upload and apply, and then the notification to wait 90 seconds. In my experience, after 60 seconds, if I select "System" from the top left, the miner is generally up and running.
6) Go to "Miner Configuration', "Advanced Settings", and select 575Mhz and then apply.
NOTE: If you have previous had your miner set to 550Mhz before applying this update, the frequency selection box will be empty by default, and will populate when you select the pulldown.
I welcome any feedback on this firmware and how it is performing.DISCLAIMER: I take no responsibility for your miner catching on fire, bricking itself, running out and marrying someone else, or any other catastrophe. These miners can be fully recovered in the event of a failure in flashing using a microSD card and the "V9 recovery" instructions, followed by flashing the original firmware back. I have successfully done this numerous times to test recovery scenarios.
