Description
I'm trying to compile k256 for ATmega328, a popular 8-bit chip on arduino boards, but I'm getting:
error: this crate builds on 32-bit and 64-bit platforms only
--> /.cargo/registry/src/github.com-1ecc6299db9ec823/crypto-bigint-0.4.9/src/limb.rs:31:1
|
31 | compile_error!("this crate builds on 32-bit and 64-bit platforms only");
The other alternatives to k256, secp256k1 and libsecp256k1 both need alloc, which I have not been able to get working yet on that platform. Any thoughts?
