I'm using NetBSD for *host* machine (i.e. my PC), not on Apad.my programs basically work on any POSIX (UNIX like) OS. if you are using non-Windows machine as a host, please try them.for now, rkflash command uses ugen device driver directly, which is only available on *BSD. but it can be replaced with libusb. libusb is portable library and it works on Linux, Mac OS X, and so on.xaueious;12963 said:I think you are the only one with a working install of NetBSD on the Apad right now. So without your rootfs we can't do anything with your script can we?
