Re: Targetting an embedded ARM chip?

["Michael D. Crawford" <crawford@goingware.com>]

Doug,

Thanks for your help.

I'm afraid it's not linux, it's a custom embedded application that's hardwired 
to drive an I/O chip.

Address 0 in the flash rom starts with a little assembly code to set up the 
stack and enable interrupts, and then it jumps into a loop where each time 
through it services some I/O requests.

It's nothing like Linux, a Linux kernel wouldn't even fit in the available 
amount of flash!

So maybe I would need to port gcc to the executable format, but I'd be surprised 
if someone hadn't already done that.

Basically the contents of the flash is a bunch of raw machine code.  Often, 
though, the images that an upload utility writes contain some extra information 
like where in the flash to upload it to.

Mike
