iMX8ULP XIP

[sb_3]

I'm haven't come across any resources for flashing the M33 on the iMX8ULP to execute in place from NOR.

I can run the flash_debug.sh script to build the app and place the sections based on the flash linker file. My assumption is that I need to run `mkimage_imx8` with the target of "flash_dualboot_m33_xip" (memory address of MCU_XIP_ADDR aligns with the interrupts/text section in the linker file). After creating that flash.bin (result of flash_dualboot_m33_xip), I'm having issues flashing with UUU. I've downloaded LF_v6.6.52-2.2.0_images_IMX8ULPEVK from the NXP page for the system, but I don't see any references to the XIP used.

My end goal is to have my M33 app execute in place from NOR and my A35 app be in eMMC.

Hello,

For this you will need to have 2 boot images, where one would be used as a flashing tool and the image to be flashed. With this you may used the following  command:

uuu –b qspi flash-singleboot.bin flash-dualboot-m33_xip.bin

Best regards/Saludos,

Thanks for the reply! I assume after running that uuu command, I can also flash the A35 image to eMMC the same as usual?
