安装Rust

https://www.rust-lang.org/tools/install

www.rust-lang.org/tools/install

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
## switch nightly
rustup default nightly
## 安装工具链 
cargo install ldproxy
## espflash espmonitor
cargo install cargo-espflash

cargo install espflash

cargo install cargo-espmonitor

cargo install espmonitor

设定RISC-V

rustup toolchain install nightly --component rust-src

rustup default nightly

查阅

https://doc.rust-lang.org/nightly/rustc/platform-support/esp-idf.html

doc.rust-lang.org/nightly/rustc/platform-support/esp-idf.html

riscv32imc-esp-espidf -C3

xtensa-esp32s3-espidf -S3

no_std库

rustup target add riscv32imc-esp-espidf # 针对 ESP32-C3
rustup target add xtensa-esp32s3-espidf # 针对 ESP32-S3

std 推荐使用 espup 下载rust对于xtensa

cargo install espup
espup install -t esp32s3,esp32c3
rustup component add rust-analyzer *** 智能提示

# 链接analyer
ln -sf ~/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/bin/rust-analyzer  ~/.rustup/toolchains/esp/bin/rust-analyzer
sudo usermod -aG uucp $USER #0r
sudo usermod -aG dialout $USER #or
newgrp dialout

配置环境变量

## config.fish
alias er='. $HOME/esp/esp-idf/export.fish'
#set -gx IDF_TOOLS_PATH $HOME/.espressif/
if test -e $HOME/export-esp.sh
    source $HOME/export-esp.sh
end

第一步 idf 下载

如果使用idf 参阅注意下载的时候网络条件, 如果不全部安装可能会有一些bug建议不要单独安装

https://docs.espressif.com/projects/esp-idf/zh_CN/latest/esp32/get-started/index.html#get-started-how-to-get-esp-idf

docs.espressif.com/projects/esp-idf/zh_CN/latest/esp32/get-started/index.html#get-started-how-to-get-esp-idf

Debug

prob-rs

open

解决一些内存的问题

https://docs.espressif.com/projects/esp-idf/zh_CN/v5.4/esp32s3/api-reference/kconfig.html

docs.espressif.com/projects/esp-idf/zh_CN/v5.4/esp32s3/api-reference/kconfig.html

通常不是espressif 官方的板子可能会遇见使用espflash 去烧写固件的时候内存对不上，这个时候就需要配置sdkconfig.defaults 这个文件也许也靠分区表来识别

配置选项有很多

例如 Build type 相关

CONFIG_APP_BUILD_TYPE

CONFIG_APP_BUILD_TYPE_PURE_RAM_APP

CONFIG_APP_REPRODUCIBLE_BUILD

CONFIG_APP_NO_BLOBS

但是我是来找flash-size 相关的内容

CONFIG_ESPTOOLPY_FLASHSIZE

https://docs.espressif.com/projects/esp-idf/zh_CN/v5.4/esp32s3/api-reference/kconfig.html#serial-flasher-config

docs.espressif.com/projects/esp-idf/zh_CN/v5.4/esp32s3/api-reference/kconfig.html#serial-flasher-config

SPI flash size, in megabytes

Available options:

        1 MB (CONFIG_ESPTOOLPY_FLASHSIZE_1MB)

        2 MB (CONFIG_ESPTOOLPY_FLASHSIZE_2MB)

        4 MB (CONFIG_ESPTOOLPY_FLASHSIZE_4MB)

        8 MB (CONFIG_ESPTOOLPY_FLASHSIZE_8MB)

        16 MB (CONFIG_ESPTOOLPY_FLASHSIZE_16MB)

        32 MB (CONFIG_ESPTOOLPY_FLASHSIZE_32MB)

        64 MB (CONFIG_ESPTOOLPY_FLASHSIZE_64MB)

        128 MB (CONFIG_ESPTOOLPY_FLASHSIZE_128MB)

sometime enconter this
