I downloaded package https://github.com/peercoin/peercoin/releases/download/v0.9.0ppc/stretch-peercoind_0.9.0-1_armhf.deb and installed on my Pi Zero W with command
sudo dpkg -i stretch-peercoind_0.9.0-1_armhf.deb
When starting peercoin with command
I receive the message
invalid command. I googled the error and I found that this may be a CPU/compiler related error. Is Pi Zero W not supported anymore with Version 0.9.0 or am I using the wrong package?
