Apologize, no, we do not have NAND. we have eMMC on board, I was just referring to the info copied from the boot log
Regarding mdio:00 I see no messages on boot log to this regard. Is there a command I can query to check it? Regarding the flasher script - THANKS A MILLION! I have now booted from eMMC on board to debian. Much appreciated. I am not sure when I am supposed to ground the WP, during flashing or after flashing? can you calrify? Also, is similar image for Angstrom available?
