0 Replies and 1199 Views Where to install ARM Exception Handlers (i.MX27 Lite Kit)  1199  0 Started by  Deleted User Hi, I want to provide my own Exception Handlers overriding the ones provided by LoLo. ARM documentation says High Exception Vectors are mapped to 0xFFFF0000. This location is however reserved for i.MX27 processor. Where can I install my custom arm exception handlers. I would like to install ARM exceptions in VRAM not over-writing locations from 0xFFFFFF00 to 0xFFFFFFFF where I can install IRQ handlers. Can some please provide me the info. Thanks in Advance, Rishi

0 Replies and 1273 Views How to connect to KEY_ROW2 using expansion breakout board?  1273  0 Started by  nedkonz We've got an i.MX27 LITEKIT and we're prototyping a product that needs a 4x4 keypad.
