ASSET recently released an enhanced product for testing i.MX6-based board designs using JTAG. I fired up this new tool on the Boundary Devices SABRE Lite board, with some fun and interesting results.

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.

In the last blog, I explored the JTAG scan path of the ScanLite demonstration board. In this article, I do a deeper dive into what options are available within ScanWorks to verify the scan path, and explore some of the underlying technology of IEEE 1149.1.

I keep taking detours! This week, I built a Linux debug image, and looked at kernel source and symbols using SourcePoint, our JTAG-based hardware-assisted debugger.

In Episode 41, Hacking the Linux Kernel, Part 2, I successfully hacked the Linux kernel, both on a native Linux partition, and within a Ubuntu VM on VirtualBox, by using the general directions within the Linux Newbies First Kernel Patch tutorial. This week, I worked towards hacking the Linux kernel using a Yocto-based qemux86 on VirtualBox, as a final step towards actually hacking the kernel on my MinnowBoard.

Rejoice, Linux kernel newbies. Last week, I hacked an Ethernet driver in the Linux kernel, but the hack didn’t work; it turns out that the driver I chose isn’t used in my native Linux image on my PC. This week, I tackled the problem again, with success! And if I can do it, you can, too.

I’ve gotten all of my Christmas shopping done early, so I managed to make some time for exploring our ScanWorks test tool. I’m taking a “newbie approach” to using the tool, initially for hacking around with boundary-scan test. There’s some pretty cool technology here.
