You should be using the *.xer5f for this (the strip version is stripped off symbols and the one without the strip has symbol information).

can_app_mcu1_0_release.appimage - SBL image

can_app_mcu1_0_release.appimage.signed - SBL image for High security SoCs

can_app_mcu1_0_release.rprc - Intermediate file to generate the *.appimage

can_app_mcu1_0_release.xer5f - ELF image

can_app_mcu1_0_release.xer5f.map - MAP file

can_app_mcu1_0_release_BE.appimage - Need to check this

can_app_mcu1_0_release_strip.xer5f - ELF image without symbol information

Hi,

Looking again at your question, the MCU1_0 application needs to be loaded by the R5 SPL and not by the u-boot.

See https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/latest/exports/docs/psdk_rtos/docs/user_guide/developer_notes_mcu1_0_sysfw.html developer note for more detials.

Karan
