I'm new to this, so the only problems I see are finding a compiler that targets the platform (ARM7, for instance, or others) and uploading the compiled firmware to the device. I used Hume [1] to program Mindstorms NXT robots (ARM7) as well as Tmote Sky sensors (MSP430). In both cases I ported the HAM virtual machine and interpreted bytecode. In the case of NXT I used the hardware layer of leJOS [2], simply ripping out the JVM and replacing it with HAM. As for
Hello, the Tmote Sky, the VM sat on top of Contiki [3], so it was possible to send HAM bytecode over the air, and the sensor would intercept it, stop the currently running program and execute the new one. Hume can also be compiled directly to C, and I got it to run on a home-brew LPC2106 based embedded platform (also with an ARM7 core) we use in education. The main problem was the size of the generated code. See [4] for details. My overall impression is that Hume could be a very nice language to program embedded systems with, given proper tool support (for starters, it's really crying for a visual editor) and a high-quality compiler.
