In Episode 30, I finally succeeded in building a Yocto Linux image for the MinnowBoard. But, it won’t boot! Is it time to drag out a copy of SourcePoint to help?

Out-of-band access between on-board BMCs and CPU JTAG chains is now a de facto implementation on hyperscale servers manufactured by the ODMs. This article describes the BMC firmware library within our ScanWorks Embedded Diagnostics (SED) product used to run diagnostics at-scale.

In the article JTAG and run-control API in BMCs for at-scale debug, I described how embedding the Intel ITP run-control library down on a service processor provides for a rich set of target-based functions for debug forensics. How might this apply to reading MSRs, such as the ones created to address Spectre and Meltdown.

In my last blog, I observed that running Yocto Linux builds with all 16 threads of my new AMD Ryzen 7 1700X machine would always crash. Running under VirtualBox and only using one thread always worked; but it took seven hours. Could I achieve a compromise?

In Episode 24, I finished off my new build machine, successfully did a QEMU image build on it, and loaded an off-the-shelf Ubuntu image into my new MinnowBoard Turbot. This week, I tackled a MinnowBoard Linux image build using Yocto, loaded it into my MinnowBoard, and also set about doing a Yocto image build for the Portwell Neptune Alpha board. But I ran into some problems.

In Episode 23, I mentioned taking a short sabbatical, because my MinnowBoard USB ports stopped working, and my 7-year-old home PC build machine crashed. The good news is both of these issues are both fixed! Let the fun begin again.
