I am working on i.MX8M EVK and was trying to bring up cortex-m4 core from the u-boot level. I didn't find any relevant documents for this!! Can you please share me the detailed steps to bring up cortex-m4 core and run some applications on top of it????
BSP: Linux 4.9.55
you can download the sdk for imx8M, then refer to the document "Getting Started with MCUXpresso SDK i.MX 8M Devices", focus on the chapter 6 "6 Running an application by U-Boot"
choose imx8M board and find SDK_2.5.0_EVK-MIMX8MQ
