RedBoot doesn't export any facility to read from flash, so for each board, such a loader would require an IDE driver to read from CF, etc. As far as I know, nobody is working on it. Would being able to update the kernel located in the onboard flash from FreeBSD be an acceptable solution for you ? Olivier
