"they are 3 features, that..." <- ah, i wasn't aware of that! i now tried this in `esp-hal/examples`: ``` diff --git a/examples/Cargo.toml b/examples/Cargo.toml index 91ab16cb..158437c0 100644 --- a/examples/Cargo.toml +++ b/examples/Cargo.toml @@ -25,7 +25,7 @@ esp-alloc = "0.3.0" esp-backtrace = { version = "0.11.1", features = ["exception-handler", "panic-handler", "println"] } esp-hal = { version = "0.16.0", path = "../esp-hal" } esp-hal-smartled = { version = "0.9.0", path = "../esp-hal-smartled", optional = true } -esp-println = "0.9.1" +esp-println = { version = "0.9.1", default-features = false, features = ["jtag-serial", "critical-section", "colors"] } heapless = "0.8.0" hex-literal = "0.4.1" hmac = { version = "0.12.1", default-features = false } ``` but that didn't help either (note: running with `espflash` in this case)
