My vote would go in the exact opposite direction: the board has to boot from NAND (or eMMC), and then step over to SATA if present. Among other things, that makes it realistic that a new developer boots it by merely plugging in the USB cable for the serial console. And don't go all u-boot on me, either, except as a quick jump to a Linux kernel+initramfs that most developers will see as the real "bootloader". That lets you use usb-storage to manage the NAND partitions, SATA if connected, SSH/telnet to the "bootloader", and so on. And then kexec to the developer's kernel if they provide their own. And manpages for same. That way, all the bad parts of u-boot et. al never see the light of day. As it should be. :-) Viola! Much easier to work with than a lot of existing hardware, and darned unlikely to brick as well. Disclaimer: the above describes how I do my boards. Get me one of these, and I'll show you. I also make pretty extensive use of multistrap et. al from the embedded Debian project, to keep the target filesystem AND developer tools in sync. This isn't me self-promoting (ok, not much). Rather, Debian is just MADE to make this stuff awesome. I'm merely a lowly user thereof. b.g. -- Bill Gatliff [email protected] -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble?
