Flashing and debugging tools#

With cargo, probe-rs can download and run a program in one step. It can also be used directly to flash and reset a chip.

cargo install probe-rs-tools

Use probe-rs directly#

# Flash an xxx.elf firmware image to the target chip
probe-rs download xxx.elf --chip STM32F405RG
# Reset the target chip
probe-rs reset --chip STM32F405RG

Supporting tools#

cargo install cargo-binutils
rustup component add llvm-tools

These commands provide the following tools:

Cargo wrapper	Native Rust tool
`cargo-cov.exe`	`rust-ar.exe`
`cargo-nm.exe`	`rust-as.exe`
`cargo-objcopy.exe`	`rust-cov.exe`
`cargo-objdump.exe`	`rust-ld.exe`
`cargo-profdata.exe`	`rust-lld.exe`
`cargo-readobj.exe`	`rust-nm.exe`
`cargo-size.exe`	`rust-objcopy.exe`
`cargo-strip.exe`	`rust-objdump.exe`
	`rust-profdata.exe`
	`rust-readobj.exe`
	`rust-size.exe`
	`rust-strip.exe`

Use cargo-size to inspect firmware size.

D:\MCU-Projects\STM32-Projects\RUST\h7\embassy\embassy_h7_blink>cargo size
    Finished `dev` profile [optimized + debuginfo] target(s) in 0.16s
   text    data     bss     dec     hex filename
  31488      80    5532   37100    90ec embassy_h7_blink

Troubleshooting#

If probe-rs cannot find a chip, check that --chip matches its supported list.
If flashing fails, check the debugger connection, board power, and debug state.
If cargo size does not run, install cargo-binutils and add the llvm-tools component.
