This is a bootloader example, which shows an example of booting Linux on A53 core and RTOS/NORTOS applications on DM R5, MCU R5 and C75 cores.
The booting is done in 2 stages(2 bootloader applications).
The SBL uses 7 appimages
Refer SBL Booting Linux From OSPI for more details on the OSPI boot loader.
Refer Enabling DDR inline ECC enablig inline ECC

and this example and IPC application is built using makefiles, and Linux Appimage is already created, in Windows, cd C:/ti/mcu_plus_sdk/tools/boot python uart_uniflash.py -p COM13 --cfg=C:/ti/mcu_plus_sdk/tools/boot/sbl_prebuilt/am62ax-sk/default_sbl_ospi_nand_linux_hs_fs.cfg

After flashing and booting the EVM, you will see below output on the UART console (Complete log is not shown)
