The UP Squared Chronicles Episode 3: Intel Processor Trace

Wow! It has been a while. I wrote Episode 2 of my open-source explorations into the AAEON Intel Apollo Lake-based Up Squared board back on June 7th. In that episode, I gave directions on how to build the UEFI debug image for the board, complete with source/symbols for consumption by JTAG debuggers like SourcePoint. In this episode, I show source-level debug with SourcePoint, and take advantage of Intel Processor Trace on the board.

Coding to the SED API: Part 1

In my UEFI Forum webinar, I demonstrated a utility function for stressing PCI Express ports at-scale using JTAG. Let’s walk through the source code and see how it works under the hood.

Debugging Intel CATERR using Embedded ITP

In my webinar with the UEFI Forum, I demonstrated some of the utility of using JTAG functionality within BMCs to perform out-of-band debug. This is a tutorial on the coding practices to use the SED API.

PCI Express LTSSM stress using BMC-based Embedded JTAG/ITP

This past week, I did a webinar in collaboration with the UEFI Forum on JTAG-based UEFI Debug and Trace. This reviewed some of the often-used tools for low-level triage of difficult-to-diagnose, intermittent bugs. Near the end, I demonstrated the usage of technology running directly down on a BMC to perform low-level functions not achievable with firmware or OS-based applications.

More Skylake Server CScripts Explorations

In Running Intel CScripts on Skylake servers, I gave a brief introduction to the Intel Customer Scripts (CScripts), and showed how to run them with SourcePoint. Today, I do a deeper dive.

The MinnowBoard Chronicles Episode 46: Using the DediProg SF100

I’ve been working from home for quite some time now, and don’t have access to all the equipment I normally would have at the office. And I’ve wanted to flash the MinnowBoard (and some other boards). So, rather than wait for the coronavirus shelter-in-place to lift, I went out and bought a DediProg SF100 of my own. Here’s my out-of-the-box experience.

Running Intel CScripts on Skylake servers

As everyone who works with server designs knows, Intel publishes a group of JTAG-based scripts called the Intel Customer Scripts (ICS, or CScripts for short). The CScripts are derived from internal applications that Intel uses for silicon validation, and they are enormously useful for board bring-up and debug. This week, I took a look at them, and ran some with SourcePoint.
