Heeeeeeeeeeeey, asking for a catgirl (that catgirl is me)Does anyone happen to have a huge archive of VxWorks documentation and SDKs and stuff I could get my paws on?Wind River is annoyingly good at keeping it all under wraps, and I'm trying to figure out the object formats and layouts for various VxWorks images and such, to no avail.

One of the hardest parts i'm hitting is trying to identify the SoC this runs on.I have the physical board, but I can't pop the heatsink off the chip because it's thermal epoxied down to it.........

It's a Freescale PowerPC something, in the line of MPCXXXX, but no idea which one specifically, or if it's 400, 500, 600, or 800 series, I can't quite tell, bweh.

Doesn't help too much with the bootloader as IIRC there is some magical config data you can stick in an I2C PROM or something that the PPC SoC will read when it starts up to configure it's special registers, and this includes doing like, memory shadowing for boot up?So the vector table can be almost *anywhere* in RAM and mirrored to the initial offset, which can then has the vectors jump to the real mapping??It's not clear, ough.
