Specifically, could I use an eMMC standard 5.0 or 5.1 complaint part on an IMX6 processor such as MCIMX6QP6AVT1AA, that ony has support for eMMC 4.41? Is the eMMC standard backwards compatible? What should I look out for when selecting such a part?
Thanks,
-Jon
Hi Jon
supported eMMCv4.4 or less according to
sect.8.5.3.1 Expansion Device eFUSE Configuration i.MX6DQP Reference Manual
http://cache.nxp.com/files/soft_dev_tools/doc/support_info/iMX6DQPRM.pdf
eMMC 5.x are backward compatible and can work with card->ext_csd.rev
modifications in linux sources given in
i.mx6 with eMMC 5.0 SDR or DDR interface? | NXP Community
Boot ROM will fall back to the eMMC4.4 standard when a higher versions
capable device is detected.
Best regards
igor
