Here you go, I wrote an extremely simple example program: http://wiki.openmoko.org/wiki/Bare_metal I don't have a physical device yet, so I've only tested this in qemu, but I can't see any obvious reason why it shouldn't work on the real thing. You should be able to upload it with u-boot in USB console mode using kermit. There should also be a way to flash it on in place of a kernel image or put it on a SD card, but I'm not familiar enough with u-boot to know how to do it. Anyway, for testing it's probably much easier just to send it via USB each time, rather than mucking around reflashing or putting SD cards in and out. You might need to adjust the for loop, as I set it based on the speed of qemu on my PC, it'll probably be completely different speed running on the device. You might like to extend it to flash "hello world" in morse code, or use an LED or the vibrator instead. You could get really fancy and have it "read" morse code from someone tapping the AUX button and make simple morse-code shell or some such. ;-) If you try it on a real device, please add instructions on how you did it to the wiki page. _______________________________________________ Openmoko community mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/community
