Failed to run on ARMv7 (raspberry pi 3)

[0xmichalis]

I managed to cross-compile grin minus the mining plugins with rust-on-raspberry-docker but I can't seem to be able to actually run the server.

can you confirm which branch / commit you used, and which rust version?

Yeah, you'll want to use the testnet1 branch. On main, the genesis block is mined on the spot to initiate a dev chain, looks like that's what's failing (assumingly because you deactivated mining plugins).

That was the issue, thanks!

[ignopeverell]

How about a little PR on the build docs to add some footnotes or troubleshooting at the bottom for ARM builds?

[0xmichalis]

I'll try to write something up latter this week.

[ignopeverell]

That would be great, thanks!
