cgminer won't run under Raspberry pi "Bullseye" system.

I'm running into the same issue. Using pi 4B 4G model + Newpack Miner

I'm running into the same issue. Using pi 4B 4G model + Newpack Miner

Found a fix:

check to make sure gekko device is still functional
remove gekko from pi

sudo apt update
sudo dmesg -C

insert gekko into pi

dmesg
cd cgminer-gekko

run application as normal.

How do I access CGminer I'm wanting to get into crypto mining and was told CGminer is a good place to start but I don't know where to access it

[Shadpw2]

you need to install it with a terminal following the readme instructions.

Hi, there is no problem on raspberry bulleyes 32 bits.
I'm installing bulleyes 64 bit on a raspberry pi and check
I'll give an update in few minutes

best regards

Hello
i've just tested it , no problem...

Double check you tune the system to acces to USB:
(acces privilege on usb fail , cgminer detect the newpac as GSH device but do not have access to it)

cd cgminer-gekko
sudo usermod -a -G dialout,plugdev $USER
sudo cp 01-cgminer.rules /etc/udev/rules.d/
then reboot and try again.

I used 2021-10-30-raspios-bullseye-arm64 , a powered usb hub and a 2pac miner

after 5 minutes of mining :

Hi Wareck,

I ran into the same issues, all on 3 different OS's. 32 and 64 bit Raspberry Pi and Ubuntu. I receive the following message:

[2022-01-23 22:44:30.934] Started cgminer 4.12.0-wrk
[2022-01-23 22:44:30.936] Probing for an alive pool

[2022-01-23 22:44:32.104] Network diff set to 26.6T

My devices are plugged in via a USB Hub. I've verified the USB Hub (BitCoin Merch) is working as it does read it.

I did attempt your fix in regards to:
cd cgminer-gekko
sudo usermod -a -G dialout,plugdev $USER
sudo cp 01-cgminer.rules /etc/udev/rules.d/
then reboot and try again.

But still had the same error.

I'm using 10-30 rasps bullseye arm 64 lite

Any ideas?

Hello
What kind of usb miner you use ?

First , be sure you build cgminer with gekko usb support
(this software will work for several usbminer but not all ! be sure you have a compatible miner)

try this
cd cgminer-gekko
./autogen.sh
./configure --enable-gekko
make

Then check your usbs :
lsusb

it will list you all usb found on your system (usb root, usb hub and miners)

then:
./cgminer -ndevs

it will answer if cgminer find your usb

if nothing found, you have to check your hub driver ou hub itself
(disconnect hub and connect one miner directly on the raspberry, if it works it's hub issue)

do not forget that there is no enough power from the raspberry to drive usbminer, you need a powered usb hub

I'm using 6 CompacF's. I'm currently overclocking them to 475mhz and averaging 1.337 TH/s.
It's been working just great, no issues now, for the past hour.

Thank you for the help with this. I have been working on connecting the gekkoscience newpac as well but I have one question. After reading the bitcoin.org forum, they suggest Building the cgminer gekko first using PC creating a file text, etc., then attaching it in to the powered up USB Hub connected to Raspberry pi4. Although I found a network connection on my Mac showing the Newpac Stick as a dial up? Has anyone noticed this before? btw, I have a Gekkoscience NewPac 130Gh/s if that makes any difference.

No problem to use gekko stick on a raspberry Pi 4 with bulleyes.
You just need to use a powered USB Hub because raspberry can't produce enough power to make stick running.

You have to follow the readme.md guide to install and make cgminer.
if you do not have skill with raspberry and linux , use my new script : https://github.com/wareck/raspberry_gekko
It will help you to automatically build a running raspberry with cgminer
