使用elf2uf2-rs在Raspberry Pi Pico上运行货物代码
使用elf2uf2-rs在Raspberry Pi Pico上运行货物代码
提问于 2022-01-01 18:43:16
我试着在Raspberry Pi Pico上运行Rust代码。使用以下方法成功构建了一个简单的“眨眼”例子应用程序(看上去是这样的)：
cargo build --release --target=thumbv6m-none-eabi我已将elf2uf2-rs安装如下：
cargo install elf2uf2-rs然后，我尝试在Raspberry Pi Pico上运行眨眼应用程序，使用：
cargo run --release --target=thumbv6m-none-eabi但是这个消息失败了，其中"rp2“是我的二进制文件的名称：
target/thumbv6m-none-eabi/release/rp2: cannot execute binary file有什么可能出错的建议吗？
这是我的Cargo.toml
[package]
name = "rp2"
version = "0.1.0"
edition = "2021"
[dependencies]
rp2040-hal = "0.3.0"
cortex-m = "0.7.2"
embedded-hal = { version = "0.2.5", features = ["unproven"] }
eh1_0_alpha = { version="=1.0.0-alpha.6", package="embedded-hal", optional=true }
embedded-time = "0.12.0"
panic-halt = "0.2.0"
rp2040-boot2 = "0.2.0"
cortex-m-rt = "0.7"
rp-pico = "0.2.0"
[dev-dependencies]
cortex-m-rt = "0.7"
panic-halt = "0.2.0"
rp2040-boot2 = "0.2.0"
[profile.dev]
panic = "abort"
[profile.release]
panic = "abort"更新
我现在添加了一个包含以下内容的文件.cargo/config.toml：
# Choose a default "cargo run" tool.
# probe-run is recommended if you have a debugger
# elf2uf2-rs loads firmware over USB when the rp2040 is in boot mode
[target.'cfg(all(target_arch = "arm", target_os = "none"))']
# runner = "probe-run --chip RP2040"
runner = "elf2uf2-rs -d"
rustflags = [
"-C", "linker=flip-link",
"-C", "link-arg=--nmagic",
"-C", "link-arg=-Tlink.x",
"-C", "link-arg=-Tdefmt.x",
# Code-size optimizations.
# trap unreachable can save a lot of space, but requires nightly compiler.
# uncomment the next line if you wish to enable it
# "-Z", "trap-unreachable=no",
"-C", "inline-threshold=5",
"-C", "no-vectorize-loops",
]
[build]
target = "thumbv6m-none-eabi"和一个包含以下内容的memory.x文件：
MEMORY {
BOOT2 : ORIGIN = 0x10000000, LENGTH = 0x100
FLASH : ORIGIN = 0x10000100, LENGTH = 2048K - 0x100
RAM : ORIGIN = 0x20000000, LENGTH = 256K
}
EXTERN(BOOT2_FIRMWARE)
SECTIONS {
/* ### Boot loader */
.boot2 ORIGIN(BOOT2) :
{
KEEP(*(.boot2));
} > BOOT2
} INSERT BEFORE .text;但是，如果出现此错误，cargo build --release命令将失败：
error: linking with `rust-lld` failed: exit status: 1
...
= note: rust-lld: error: cannot find linker script defmt.x我使用MacBook和M1苹果硅芯片，这可能是一个相关的问题AArch64系统下的锈蚀-lld问题。

我现在已经在Raspberry Pi Pico上运行了代码。
第一个问题是，我没有创建包含要使用.cargo/config.toml“运行”的指令的elf2uf2文件：
[target.'cfg(all(target_arch = "arm", target_os = "none"))']
runner = "elf2uf2-rs -d"另一个问题是，我的.cargo/config.toml还包含了对系统中没有的护卫的引用，所以当注释掉这一行时(在rustflags下)，用cargo build --release编译的代码在带有cargo run --release的Raspberry Pi Pico上运行
