No hashrate when mining with CPUminer

Question

I've set up a monero-miner for my Raspberry Pi (for educational purposes) and when I run my miner deamon the log looks like:

[2018-06-28 07:58:10] Using JSON-RPC 2.0

I know that the Raspberry Pi is not optimized for crypto mining but 5-20 H/s should be possible. To start my deamon I use

./minerd -a cryptonight -o stratum+tcp://xmr.pool.minergate.com:45560 -u <my address> -p x -t 4

as explained here: https://www.electromaker.io/tutorial/blog/cryptocurrency-mining-on-the-raspberry-pi-60

there it says:

To start mining Monero, run:

./minerd -a cryptonight -o stratum+tcp://xmr.pool.minergate.com:45560 -u [email protected] -p x -t 4

the money I mined is also not appearing in my wallet.. (neither on my MyMonero wallet nor on my MinerGate wallet)

What did I do wrong?

Any help is very appreciated

Answer 1

You probably using a XMR Address with the XMO pool port. Change your port to 45700

Answer 2

Finally solved it... I was using a 3-4 year old miner. The mining/hashing algo was changed in April (May?) I was using the old and incorrect miner, thus bad shares...

I installed a new miner: xmrig with the following commands:

apt-get install -y git build-essential cmake libuv1-dev libmicrohttpd-dev 
git clone https://github.com/xmrig/xmrig.git
cd xmrig
mkdir build
cd build
CFLAGS="-march=armv7-a -mfloat-abi=hard -mfpu=vfpv3-d16 -O2 -pipe -fstack-protector-strong -fno-plt" CXXFLAGS="-march=armv7-a -mfloat-abi=hard -mfpu=vfpv3-d16 -O2 -pipe -fstack-protector-strong -fno-plt" cmake .. -DWITH_HTTPD=OFF && make VERBOSE=1

Did this on a brand new Raspberry Pi 3B+ with armv7 CPU arch and new raspbian. Worked well. Getting about 9-10 H/s.
