How to choose a firmware partner: Ask if it's policy to enable the watchdog timer. The correct answer is "no". If they say "yes" then you know that their code is dodgy, and/or their hardware is vulnerable and if the WDT is not going off occassionally, it probably will after the next modification.

I recently was contacted by a headhunter about a job working on "embedded firmware". Since I've begun to notice this term can imply many things, I tried to ask whether it was an area that really interested me, whether the work would involve developing device drivers. The headhunter was stupefied, asking whether that was some sort of application, but I was able to sync up with him again when...

The system uses a 68030 controller and I pulled the eproms and made a binary image in order to disassemble. I have a very good reason to believe that HP used a variant of HP uni...
