It's doesn't work for me too. Can you set wrong date to hwclock and try boot again?

It's mean that if I make: hwclock --systohc --localtime in debian-3.8-wheezy-3.4.107 than reboot from SD-card with debian-4.0-wheezy-4.1 all must be work? Yes? In theory?

You want say that problem is that hardware clock is not set properly?

Yes, already understand this. I'm thought that when run "nand-sata-install" from SD-card and choice install rootfs to HDD, bootloader will be installed to NAND. It's not true, bootloader will be on SD-card. Please add to FAQ: If you want boot from NAND (not from SD card) you must run "nand-sata-install" twice: 1 - install from SD-card to NAND 2 - then remove SD-card, boot from NAND and run "nand-sata-install" second time. Only if you connect USB <-> serial converter (3.3v ONLY!) to UART0 then press any key when see "Hit any key to stop autoboot". Not working if you will be using keyboard and monitor.

Cubietruck_Debian_3.8_wheezy_3.4.107 working fine for me but can't boot from SSD. After nand-sata-install rootfs on SSD but booting only from SD-card. Disconnect battery and AC power adaptor but 4.1 still not booting...

I confirm, not working
