Booting more than one FreeRTOS image in the same power-on session will likely not work, with only the first boot being successful. Occasionally, booting multiple images may result in a data abort.
Workaround : Reset the module between image boots.
I2C3 muxing
I2C3 is muxed incorrectly.
Workaround : Update file cl-som-imx7-freertos/freertos/freertos_source/examples/cl_som_imx7_m4/pin_mux.c at lines #112 and #114 to use MUX_MODE(4) instead of MUX_MODE(5) and rebuild the I2C demos.
