Debug Trick Uses CPU Cache as RAM

by Bryon Moyer

Embedded tool company Asset Intertech is giving away a free e-book that teaches a clever little debugging trick: Use your CPU’s on-chip cache like RAM so you can bring up a non-functional board. If your new hardware won’t even boot, it’s hard to figure out where the hardware/software problem(s) lie. With no working RAM you can’t even run diagnostic routines. But your processor’s on-chip cache is always there and always reliable. Give it a shot. The download link is at http://bit.ly/XzK0nI.
