Based on my experience I would prefer to skip the experience of trying to get the wallet running on a Raspberry. The experience even on faster devices is, that it didn't manage to finish the download in like 1.5 weeks. Therefore this seems like a very bad idea. But never tried the wallet on ARM in first place.
On the other hand I'm wondering, if you ever got the miner running on the Raspberry. Because my experiences with that one were quite horrible as well and I didn't get it running until this day. And I tried for a few days to do so. While I don't hide, that I'm a beginner with mining and despite knowing my programming basics that I'm not quite a developer either, it is worth mentioning, that I looking back at many years of Linux experience and quite some years with Raspberries as well. So I'd say, if I have this problem, many other with this idea are going to have it as well.
The usual is libcurl allegedly blocking https... which is not the case. Because I have it all installed and https with CURL for example works just fine. Recompiling doesn't work either. Neither with the build script, nor, was it cmake that also compiles libcurl? Something like that... So, seems it's just the miners that don't work properly. Same problem on aarch64, ARM32 and x86-32 and with both, Raspbian and Arch. On Linux 64 works just fine, but not where I want it.
And I've tried various options, including a full recompile including libraries in the build sh file and the result is, that while it runs through the compilation process and the libcurl file gets place where it should be according to the build script and the mining scripts are there, the binary is not.
So, if you got the miner running on a Raspberry, let me know and let me know HOW you did it! Because for me that is actually the bigger issue.
