Hi Yan,
AM57x RTOS package has tools for pinmux, clock confguration, EMIF/DDR configuration, bootable SD card creation, etc
There are also Boot and Flashing tools in the RTOS package. The Boot and Flashing Utilities for all devices is located in the PDK package under the path pdk_<device_name>_x_x_x\packages\ti\boot\sbl\tools.
Depending on the boot design you need to implement, the boot and flashing tools that are used for formatting and booting the SBL can also be leveraged to format and boot the application image directly. The flash-writing utilities for different EVMs can be located under the path pdk_<device_name>_x_x_x\packages\ti\boot\sbl\tools\flashWriter.
For more details, refer to below user guides:
Regards,
Pavel
