Topic: Alchemist updated support added for RPI with a broke controler - page 2. (Read 2453 times)

Could you please also post here a link to correct USB-UART dongles model(s)?

right now this is what minera is doing on a cubieboard 1 PI with 5 Alchemist 256 miner blades on Ubuntu 14 with a 7 port usb 3 hub and a 2 k server PSU with six pin PCEI plugs with no heat from them yet been running about week off and on that way.

I can upgrade to Ubuntu 16 and have but minera has issue with PhP 7.0 sense 16 no longer supports php5 .....im a ware you can share php 5 with 16  but it's not the same.

Minera is Showing the right totals but most of the time it doesn't. hash it does  all ways and the temps you see is the cubieboard not the miner .



Just made exact same post in the minera thread !!!!...

Just discovered all you need setting wise is




and fix it above !!!! .

Thanks for the plug toptek!

FYI Some CP210X dongles come with the RTS or DTR pins. I ended up writing support for both those pins in the driver, so you can buy either dongle and it will work if you connect pin 6 on the hash board to either of those. And yes my old guide is wrong on the pinouts, pin #5 is the GND pin not 4.

Well, TODAY i have the first board hashing!! NOW i'm very happy.  

Now i found my problem: this setup do NOT WORK with the RASPBERRY PI B+. You need to use the Raspberry Pi 2 instead...  
And finally, the pins are:

1 is RX
2 is TX
5 is GND  <-- This is the correct.  NOT THE 4 pin
6 is Board Reset

Thank you very much for all your work; with my free-time i did not could install the rpi2 adapter propelly.

 I think it safe to say this works , after three hours no major issue other then normal mining issue's we all deal with :

 

got one board rolling .

Awesome info - thanks for sharing with the community!

here's the new support added i paid for it started from this thread the other day

https://bitcointalksearch.org/topic/wtb-alcheminer-controller-board-100-working-1452931

I want nothing in return if you feel the need to donate, donate to jstefanop he deserves it more.  

I paid and got what i wanted + i want to share it . Right now im stuck till i get the right dongles sent . mine that were sent have no rts pin even thu the add said it did sigh i made sure with my new ones coming, I  was kind of ass hole to the sellers for the miss info,

jstefanop:

Ok I added very rough support for the boards to be run with the USB->UART dongles with my bfgminer driver on a Rpi. I have not tested this as I don't have a spare board or dongle to test but this *should* work. Steps to get it running below

-Clone this branch off my repo: https://github.com/jstefanop/bfgminer/tree/alcheminer_USB-Dongle_Support
-Build on pi using same bfgminer build instructions in my alchminer thread (let me know if there are compilation errors)
-Connect the pins from the dongle to the alcheminer boards...you need to connect the reset pin from the board to the RTS pin on the dongle (also remember to reverse the TX-RX pins)
-Use the same command line options to start bfgminer and specify the -S /dev/ serial port your dongle is assigned too, and add the following option to turn on the USB dongle mode  --set ALC:mode=1

Let me know if it works!

I Added this from his post on the ltc forums with some tweaks I use or what i call them : https://litecointalk.org/index.php?topic=27370.0




you may need more library's as well depending on if you use ubuntu 16 standard server for the RPI 2and 3 for to work right if there is a issue try this



Then plug all the cables etc into each board to the right dongle pins like this :UART connect on the hash boards is labeled 1-6 Pin 1 is RX, 2 TX, 5 GND, 6 Board Reset , on the dongle : reverse the TX-RX pins : so like this TX to RX and RX to TX on the dongle form the hash board , GND to GND , RTS to RTS then to your 8 to 10 port self powered hub and plug the hub in to one of the USB ports on your RPI, turn on the miner then type.


 That should list what USB port is being used .

 then run BFG with the right USB ports set up some thing like this:


Valid clock ranges are between 200-400 with multiples of 16 (so  320, 336, 352 etc)
