Last week, I wrote about my out-of-the-box experience with the Minnowboard Turbot, and how easy it was to start JTAG-based debugging on it with the SourcePoint tool. This week, I explored the UEFI shell, and updated the board firmware.

It is often part of a hardware validation test suite to initiate multiple PCIe bus retrains, looking for hardware design issues, or LTSSM RTL bugs in the device under test. These test suites take a very long time to run. Is there a way to speed them up?
