ASSET recently joined the UEFI Forum and, enjoying the benefits of membership, we came across this paper extolling the virtues of the technology and clarifying some common misconceptions.

More efficient BIOS printf trace

Conventional printf statements within a BIOS being debugged add a lot of “backpressure” due to the overhead within the printf routine and the cost of directing the output through a slow serial port. This slows the debugging process down, and may even mask some time-sensitive bugs. Is there a better, more non-intrusive way?

In a previous blog, I described how the ScanWorks Embedded Diagnostics (SED) utility runs Intel CScripts nearly as fast as legacy methods. This applies in particular using the Emulex Pilot4 BMC, with its on-chip JTAG Master.

Programmers debugging BIOS (known as UEFI today) have debugged complex systems without using any Trace features for 20 years. This is all about to change.

As the UEFI Forum continues to make advances in the technology behind what is still called the BIOS (Basic Input/Output System), ASSET has joined this standards body to assist in the debug of its latest features.

In a previous blog, I shared some prospective information on the real-time performance of Intel CScripts, when run on our SourcePoint debugger, versus legacy methods. This article contains quantitative measurements, and supports the theory that SourcePoint yields much higher throughput.

Catastrophic events within an Intel processor will often manifest themselves with a “hung” or “wedged” system. What causes these events, and how can they be resolved?
