SK-AM69: The file mksdboot.sh cannot be found

Part Number: SK-AM69

Tool/software:

Hi Expert,

The customer wants to use eMMC to boot the computer.
Follow the documentation

https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-am69/10_00_07_06/exports/docs/linux/How_to_Guides/Target/How_to_flash_emmc_device.html

Requires mksdboot.sh
But the customer searched the entire host-side compiled folder and could not find mksdboot.sh.
Is there a more detailed location for mksdboot.sh that can be provided?
Or what files do mksdboot need to compile before it can be generated?

Thanks

Daniel
