sdrr-fw-parser

Parses Software Defined Retro ROM (SDRR) firmware.

This is a no_std compatible library, which can be used in both std and no_std environments and can read and extract information from SDRR firmware - either from

• a binary file
• an ELF file
• raw bytes, e.g. from bytes read directly from a device's flash or RAM

This is used directly within the SDRR repository, by:

• sdrr-info - PC based tool to analyse SDRR firmware source code

It can also be used by external tools.

Typically used like this:

use sdrr_fw_parser::SdrrInfo;
let sdrr_info = SdrrInfo::from_firmware_bytes(
    SdrrFileType::Elf,
    &sdrr_info, // Reference to sdrr_info_t from firmware file
    &full_fw,   // Reference to full firmware data
    file_size   // Size of the full firmware file in bytes
);

sdrr-fw-parser

Crate to handle parsing an SDRR firmware image.

This can can be a .bin or .elf file - or could be the contents of an STM32's flash memory. It supports no_std environments, for adding to embedded applications, or std for use in PC-based tools.

A PC-based reference implementation is provided in the sdrr-info tool, which is used to parse and output the contents of a firmware image when you run make info or make info-detail.

A reference embedded implementation using this crate is Airfrog, which is a tiny $3 probe for ARM devices, that can be used to inspect the firmware and runtime state of the SDRR device, and change its configuration and ROM data - while it is serving ROMs.
