In the last episode of the MinnowBoard Chronicles, I shared my progress with building a qemux86 reference image using the Yocto Project. I’m pleased to say that the build is complete! Here’s how I did it.

I have a little secret to share: even though I may make it look easy, getting Linux onto my MinnowBoard is hard, hard work. But it's very rewarding.

After working with UEFI over the last 18 episodes of the MinnowBoard Chronicles, I’ve decided to install Linux on my MinnowBoard. It is turning out to be harder than I thought.

The news is out! Intel today announced its Intel Xeon Processor Scalable Family, codenamed Purley or Skylake-EP. ASSET of course has supported this silicon since its earliest beginnings, with the SourcePoint and ScanWorks Embedded Diagnostics products. Read the full press release here: ASSET releases new benchtop and remote debugging applications for Intel Xeon Processor Scalable Family.

In two previous articles, I looked at the JTAG access port from a security perspective, and considered what exposure the choice of BMC operating system might have on a platform supporting At-Scale Debug. Now, let’s consider the root of all trust, the silicon itself, and see what options exist for locking it down.

Given that they are network-accessible, BMCs present an attack surface. Which operating systems are hardened enough to be secure against malicious actors?

Security through obscurity is not a meaningful means to mitigate malevolent attacks. With the greater forensics capabilities offered by At-Scale Debug (ASD), how are platforms protected?

In my last article, I used Last Branch Record (LBR) Trace to manually capture UEFI program flow source and destination addresses. This week, I look at the associated instruction opcodes and mnemonics and try to figure out what is going on.

My curiosity got the better of me this week. I decided to play detective, and see what I can learn from LBR trace data if I pretend I don’t have access to the source code.
