yes, you cannont execute asm code on arm.... you need to modify the code

maxibelino commented 6 years ago

hi, @manfire , how do you do that? thanks!

Zenitur commented 6 years ago

I'd tried to compile cgminer 3.7.2 on Raspberry Pi. It was successfully compiled. When I tried to start it (with scrypt algo), it didn't show any hashrate and results, but GPU temperature rises. After few hours, the program stopped to work and shutdown.

I'd used nightly build of VC4CL, because there is no one stable release at this moment.

@Zenitur ...this would connect to a remote node? i don't realize how would it download all the blockchain into the RPi (more than 40 GBytes) Sorry, but i also don't know what is VC4CL....

Zenitur commented 6 years ago

maxibelino, you don't need to download all the blockchain. Did you know what is a mining pool?

maxibelino commented 6 years ago

yes you attach to a mining pool to mine "in group" and share profits

Hi! i compile sgminer on windows and got this issue

Does anyone know how to solve, please help
