Part Number: AM625

Hi TI

i get the figure from TI that the OSPI device's theoretical application boot time is around 1.1s, what is the value in case of booting from EMMC 5.1device.

Hi Xiaoyu,

The similar performance measurement on eMMC is planned, but we don't have such boot time numbers for eMMC yet. By comparing the un-optimized U-Boot+Linux boot time between OSPI and eMMC on AM625 SK, eMMC performs very close to OSPI.
