Hi Cesar,

Boot app only support OSPI and SD boot media

Unfortunately EMMC is not supported https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/09_01_00_06/exports/docs/pdk_jacinto_09_01_00_22/docs/userguide/jacinto/boot/boot_app.html#steps-to-boot-different-os-via-different-boot-media
