Asset Intertech on debugging Minnowboard firmware

Asset Intertech has a blog series on debugging Minnowboard firmware using their debugger product. Even if you can’t afford their product, you can still learn about debugging UEFI firmware from this post. 🙂

The Minnowboard Chronicles – Episode 3

As I continue the journey to learn about the internals of UEFI and to debug it with SourcePoint, I encounter some issues doing the firmware build. Last week, I played around with the UEFI shell, and then updated the firmware on my Minnowboard to the latest release (v0.94). Then, I used SourcePoint to look at disassembled code when the platform was sitting in the UEFI shell, waiting for keyboard input. From last time, we can see a number of “INT 3” instructions, with opcode CC. […]





new Minnowboard variant

It sounds like this new Minnowboard Turbot Quad Core from ADI will be out in December for around $190.

“ADI Engineering announced an upcoming Quad Core varient of the MinnowBoard Turbot that will used the E3845 SoC. Compatible with the existing MAX and Turbots this brings a new level of performance to the SoC for those computationally expensive tasks.”

From the Netgate pre-order page:

Improvements over MinnowBoard Turbot Dual Core
* Twice the core count. Higher clock speed.
* Over 2.5 times FASTER than the MinnowBoard Tubot dual core.
*  Better Ethernet! This board has Intel i211 vs Realtek NIC.
* Fansink keeps it cool! Suitable for higher temp applications.

Intel UEFI updates for Minnows and Braswell

Intel has released UEFI updates for the MinnowBoard Max, MinnowBoard Turbot, and Braswell boards:



Intel updates Firmware Engine

Intel® Firmware Engine Release 2.0.0
Program installer for Microsoft* Windows 7/8/8.1/10.
Includes program and MinnowBoard Max and MinnowBoard Turbot platform support.


Intel: please port Firmware Engine to Linux (and FreeBSD, which also has UEFI support), the current Windows-only release only helps Windows subset of your target firmware vendor ecosystem. Thanks!


update on Atom’s demise: Minnow’s swim on

It appears that the Minnows may be spared from the recent news of Atom’s demise, see the below comments from Intel on the subject:





Minnowboard is part of GSoC16

The Minnowboard project is part of the Google Summer of Code project. If you are a student, this might be a good opportunity for you to start on a new project. There’s dozens of things that should be done with coreboot, U-Boot, UEFI, SeaBIOS.

According to the wiki, students will get a Minnowboard Turbot, and some cables.

The MinnowBoard project is an open hardware platform that uses Intel Architecture. While the project, overall, is focused on hardware there are a lot of things surrounding this effort that can, and are, useful both to the project and to the greater open source community. As such the MinnowBoard project (from a GSoC perspective) is more of an umbrella giving a home to a number of other projects to collectively work on and around the enablement of the MinnowBoard. These projects not only help the MinnowBoard project, but also enable other open source projects and software. These tend to be smaller projects or projects that are more tightly focused and would not otherwise be apart of GSoC, but that could benefit from additional contributors.

Board Design Files for Minnowboard Turbot available

John Hawley of Intel announced on the Minnowboard mailing list the availability of board design files for the ADI MinnowBoard Turbot, released by Mentor Graphics.

3D STEP files now available – Courtesy of Mentor Graphics. Just wanted to let everyone know that Mentor Graphics has just released accurate STEP files for ADI MinnowBoard Turbot. I know there’s been folks interested in getting these for a variety of reasons, and while I’ve attempted to respond to the folks who have pinged me directly, I wanted to make sure that everyone is aware that those are now available. If you’ve got any problems with them, let me know, and serious thanks go out to Mentor Graphics for doing this!

Two quotes from the Minnowboard wiki:

“The design files are released under Creative Commons CC-BY-SA.”

“The MinnowBoard Turbot is intended to comply with all requirements and guidelines set forth by the Open Source Hardware Association (OSHWA).”

The word “intended” is probably significant; regardless I’m happy to see Minnowboard intending to be OSH. I hope they fulfill this intended goal! 🙂
