Embedded Rust Debugger (ERDB)

Extension for the debugger Embedded Rust Debugger (ERDB).

ERDB is a rust debugger for embedded systems. It currently only works on Linux, and is only tested on a STM32F411RETx dev board.

Features

• Flash target.
• Continue, halt, step, and reset program.
• Set and clear hardware breakpoints.
• Show variables, registers, and stack trace.

Requirements

Check that ERDB is installed by running erdb in a terminal, if not installed then install it with the following command.

cargo install erdb

The debug target must be connected to the host, and the binary must contain the debug information section.

Extension Settings

It is required to fill in some information in the launch.json file. The following subsections describe some of them.

Program

The absolute path to the program binary, which can be used to flash the target, and contains the debug information.

If you get the error No such file or directory then this path is not set correctly.

Examples

• "program": "${workspaceRoot}/target/debug/<program name>"
• "program": "${workspaceRoot}/target/thumbv7em-none-eabi/debug/nucleo-rtic-blinking-led"

Chip

The MCU chip type that the debug target has.

Example

"chip": "STM32F411RETx"

Known Issues

• The launch command does not build the program, therefore always build before debugging.
• Only supports having one debug session.
• All step buttons perform the same type of step operation, that is stepping a single machine code instruction.
