This past week, I attended the AUTOTESTCON 2019 conference, the premiere Defense Automated Test Equipment show, that has the theme of “increased mission effectiveness through advanced test and support technology”. As you may have seen, I was honored with the “Walter E. Peterson Best Paper on New Technology” award for Mitigating JTAG as an Attack Surface (note: it might take a little while for the paper to be posted on IEEE Xplore; you might have to check back later).

In a prior blog, I wrote about the JTAG specification’s upcoming 30th anniversary, and reflected on how it has evolved over the years, and the powerful use cases it can be put to. This week, we look at how to secure the JTAG interface, to prevent its abuse by bad actors.

JTAG is coming up on its 30th anniversary. And some would say it’s older than that. As I prepared for doing an introductory presentation on this amazing technology, I got a chance to reflect on how useful it has become, and what the next 30 years might be like.

Do you know how it feels when you have an itch, and you just have to scratch it? Well, after an extended hiatus from writing, I felt an overwhelming compulsion to do another MinnowBoard image build with source and symbols, do some more exploring, and then blog about it.

Eureka again! I finally figured out how to use Yocto to build a Linux kernel with all of the symbolic debug information, so that I can see all of the source code and symbols within SourcePoint.

In Part 3 of this series, I looked at the JTAG scan path of the ASSET ScanLite demo board, and explored some of the fundamentals of IEEE 1149.1. This week, I do some fault insertion on the scan path, and see how that is detected by boundary scan.
