Has anyone done any work with the Avent Digital Surveillance board?

I'd love to hear that uClinux is already running on it; but I'd be interested to hear *anything* about it (good/bad/etc..).

it lacks a UART which means currently you cannot get a console, so it makes it pretty difficult to do u-boot/linux on it

 

we're working on a console-over-jtag which would mean you could then do things on the board ...

Yikes!  I didn't realize it didn't even have a serial port.  I just bought one thinking I could do some blkfin/uclinux work on it to gain experience with the '561.  uMon doesn't mind running without a serial port, so the bootloader isn't a problem; however, it will be painful to get uClinux going without that.

 

Has anyone started down this path?  I'll help (or start) if it makes sense.

According to the block diagram of the schematic, there is RS232 somewhere on that beast.

Looks like RX/TX are on that PS-2 style connector, but no cable comes with the kit to easily connect up to this.  Guess I'll make one up and see if anything works (unless you already know something I don't know, please inform)...

Ed:

 

We were told by our legal guy that the license that the schematics were distributed under were incompatible  with open source developments. (some crazy clause about not redistributing information gathered from looking at the hardware design - which we would need to include in kernel and U-Boot files).

 

Since we did not agree to the license, we did not download the schematics/documentation - So, like Mike said - we have a board, it is waiting until the JTAG/console stuff is working before we look at it it too much detail - since the pain of reverse engineering things will be a hastle.

Ok, I too bad.  I guess that means that for now I'm on my own!! :-(

 

How is it that having JTAG will allow you to get around this?  If you can't legally look at the schematic, then you can't see how the periphery is wired up right?  Especially since it uses the BF561, all periphery is glued on.

JTAG has a background data channel which we can use to emulate a UART
