I want to try experimenting with running low level code my Nexus One phone, but I can't find a suitable manual describing how.
As far as I know, the VROM does some initial bootstrapping before jumping to the bootloader which would then unpack and load the Linux kernel. What I want to be able to do is to pass a custom image to the VROM and make it jump to my entry point (place an image at a specific address and make the CPU jump to it).
Is it possible? And is there any documentation describing the SoC used by Nexus One?
