Good point. GPIOs are indeed treated separately. (Phew, when I read your question, I briefly wondered "and what if they aren't preserved all the way through".) However, regarding Steppingstone. The 6410 manual says: | The [SLEEP] exiting sequence is as follows: [....] | 4. NFCON copies boot code from an external NAND device to the stepping | stone if the boot device is NAND. | (XOM[4:3] == 2'b00) So I wouldn't bet on SD boot to be different. Anyway, I just wanted be sure we don't accidently depend on a feature that may not be there. - Werner
