| Note that this does not work with armv6 (found e.g. in Raspberry Pi 1 and Zero). Previously, you could use the linker in https://github.com/raspberrypi/tools, but this is now too old and will give an error when compiling Librespot (since `3e85d77bfb3520e16c35bb7db3912c76e8cc90d7`).

I compile librespot for armv6 using the official raspi tools no problem. But I don't use cargo cross. I suggest just stating your method doesn't work for pi 1 and zero.

I'm also not using cargo cross. After commit 3e85d77 I get an error from the rpi tools linker saying it found dwarf version 6, but only supports versions 1-4. Maybe I'm using a newer version of Rust (I'm on 1.82.0)?

I'll update and see what I get. Does this happen even when compiling with the release profile?

@oyv friendly nudge - did you get around to testing what @kingosticks asked?
