The Embedded USB Debugger (EUD) is a sophisticated tool developed by Qualcomm to enhance the debugging and development processes for embedded systems.
It functions as a mini High-Speed USB on-chip hub, providing USB-based debug and trace capabilities. EUD is particularly useful for diagnosing and resolving issues in complex embedded systems by leveraging the widely supported USB interface.
EUD supports a variety of peripherals, including:
These interfaces enable seamless communication between the host system and the embedded device, facilitating efficient debugging.
To function properly, EUD relies on several libraries:
To build EUD, you can follow these steps:
autoreconf --verbose --force --install
../configure --enable-dll
(ignore --enable-dll
if building on Linux).make
to compile the project.EUD is licensed under the GPL-2.0 or BSD 3-clause “New” or “Revised” License. For more details, refer to the LICENSE file.
While EUD offers powerful debugging capabilities, its use is somewhat restricted.
The tools necessary for utilizing EUD fully are not openly available and require access through the Qualcomm Package Manager, often involving non-disclosure agreements (NDAs).
This limitation hinders widespread adoption and use of EUD outside of Qualcomm’s ecosystem.
In summary, EUD is a valuable tool for developers working with Qualcomm chipsets, but its accessibility and usability are constrained by proprietary requirements.
