Blackmagic - debug ARM and RISC-V hardware

Blackmagic is a GDB server for embedded hardware that translates GDB remote protocol messages into JTAG and SWD commands. It functions as an ARM and RISC-V debugger and hardware debug probe manager, enabling users to inspect memory, control execution, and manage registers on ARM Cortex and RISC-V cores.

The project distinguishes itself by acting as a remote hardware debugging bridge that can stream GDB server traffic over TCP/IP to control physical hardware from a remote machine. It also provides a JTAG and SWD interface to connect host computers to target hardware and serves as an embedded flash programmer for reading, erasing, and writing firmware images to on-chip and SPI flash memory.

The system covers broad capabilities in debug probe management, interfacing with various hardware probes such as CMSIS-DAP, J-Link, and ST-Link. It includes features for embedded device monitoring, such as capturing real-time logs and data using semihosting or serial wire output, and supports automated target identification to remove the need for configuration scripts.

The software communicates with host operating systems using a standard USB CDC ACM virtual serial port to eliminate the need for proprietary drivers.
