ASSET InterTech published a new e-book: Cache-as-RAM for Board Bring-up of Non-booting Circuit Boards. The technical paper takes a close look at how run-control tools can employ a processor’s on-chip cache memory instead of on-board RAM memory to boot non-booting prototype circuit boards. The technical publication is available now.
Cache-as-RAM for Board Bring-up of Non-booting Circuit Boards
Designers often face a catch-22. They have to diagnose a non-booting prototype, but they can’t debug anything without some software running on the circuit board. Fortunately, run-control tools can help designers employ CPU cache-as-RAM methods to find faults like defects in the memory controller or in its link to the CPU. Simply applying power to a prototype doesn’t help the engineer much because when the board won’t boot, he doesn’t know whether it’s a hardware or software problem.
