The +nightly-2021-01-07 is because #29, the README.md says.

cargo build -Z build-std=core --target avr-atmega328p.json --release

What I did to get a succesfull build:

--- a/src/main.rs
+++ b/src/main.rs
@@ -3,7 +3,7 @@
 #![no_std]
 #![no_main]
 
-use ruduino::cores::atmega328 as avr_core;
+use ruduino::cores::atmega328p as avr_core;
 use ruduino::Register;
 
 use avr_core::{DDRB, PORTB};

I don't know how good or how evil that is.

Thing I'm trying to say: blink did not compile for me, I had to make a modification to get a target/avr-atmega328p/release/blink.elf.

Note: How good that blink.elf is, is currently unknown.

I recently updated the main.rs file so that rather than hardcoding the atmega328, it uses use ruduino::cores::current::{DDRB, PORTB};, using ruduino to detect the device that is being targeted. I suspect this issue is fixed now, specifically in cfb8451.

Reporting a clean compile, taking #29 workaround in account.
