the NXP ® i.MX6 processor. Eight lanes are used for data. Changes to the onboard eMMC may occur during the lifespan of the module in order
to keep up with the rapidly changing eMMC technology. The performance of the newer eMMC may vary depending on the eMMC technology.
Note
For adequate operation of the eMMC, ensure that at least 15 % of the eMMC storage is reserved for vendor-specific functions.
