Hi TI expert

Do you have the boot KPI with eMMC on the EVM? as the boot information we had before is using OSPI .

Hi Weicheng,

I am not sure what OSPI boot KPI information you have, but the eMMC boot time on SK-AM62 is 1.1 seconds. Here are the measurement conditions:

- Using Processor SDK Linux v8.6 (The kernel in SDK8.6 boot time is much shorter than the kernel in SDK8.3 does);
- RootFS on eMMC is the Tiny rootfs provided in SDK8.6 and optimized (SysVInit scripts);
- The boot time is measured from MCU_RESETSTATz (J9.23) to the Linux login prompt.

Hi Bin

[The DNA content is removed]

We would like to know the CAN response in eMMC boot mode(SDR,50MHz) w/o BIST.

Thank you!
