I'm looking at the same, but for seriously different specs.
My interest would be to run ocaml apps on a Raspberry PI baremetal.
Basically what openmirage does for the cloud (x86 VMs) but for
Raspberry PI and similar dimensioned arm boards.
So targets would be ARMv6 / ARMv7 cpus with 128MB - 2GB ram, USB,
HDMI, ethernet (often via USB), serial and an SD card.
I'm familiar with the hardware side, how to boot, how to initialize
the devices, how to get a picture to show on the HDMI and so on. What
I lack is knowledge in creating a new runtime library for ocaml that
runs directly on the hardware, or with just a verry thin hardware
abstraction layer.
Any pointers for how to do that?
