Part Number: AM6442

Hello TI expert,

when booting up from OSPI or SD device, device enter the u-boot and hence I type the coommand "print"

That shows all evn variable.

1. I have a question that is why evn is read from eMMC while booting from OSPI or SD?

2. I want to use the ospi.evn.txt as default case. How should I do? Please give me your suggestion.

Thanks

    Hi Thinh,
    Yes, "saveenv" u-boot cmd saves environment variables to eMMC on AM64x EVM.
    You may refer to another e2e post on "saveenv" on eMMC on the current SDK 7.3.1 release.
    e2e.ti.com/.../3750765
    For your reference, the default environment variables for AM64x EVM are configured in files "u-boot/include/configs/am64x_evm.h"...
    Best,
