A couple of questions popped up before I started poking around inside a DM800 HD PVR DVB-S reciever I've promised to take a look on for a friend.
It's having the infamous "error" display, won't start ethernet correctly and a lot of other problems. And after looking at the horrible DreamUp software, I decided to make some stuff from scratch instead.
Since there's a lot of people having trouble with "file too big" errors and trashed / bricked boxes, I thought I'd pull some bits together for people in need of some info for reflashing and fixing the Broadcom BCM7401 SoC through JTAG programming.
There's some info available for the DM500, but those guides have been written by people not having a clue whatsoever of what they're up to. They've just found an article somewhere and have no experience.
But remember, doing a JTAG reprogramming is voiding your warranty, and if you screw up, you can always use your box as a frisbee from a cliff wall or something.
The article will be primarily published first at Welcome to the Frontpage (http://xtal.lewdesign.com), but guides and software (GPL) will be placed here at digital-kaos too. For obvious reasons.
