title: Synchronous External Abort on ARM
body: <p>I was building a bare metal application on ARM Cortex A9 Pandaboard, and I got Instruction Fetch Abort frequently. When I dump IFSR Register I got 0x1008. I've read the reference manual, and I understand that 1008 was Synchronous External Abort. The problem is what synchronous external abort means and where does it come from? Thanks for your help.</p>
