This is a bootloader example, which shows an example of booting Linux on A53 core and RTOS/NORTOS applications on DM R5 and M4 cores.
The booting is done in 2 stages(2 bootloader applications).
The SBL uses 6 appimages

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/am62x-sk-lp/default_sbl_gpmc_nand_linux_hs_fs.cfg

cd ~/ti/mcu_plus_sdk python uart_uniflash.py -p /dev/ttyUSB0 --cfg=~/ti/mcu_plus_sdk/tools/boot/sbl_prebuilt/am62x-sk-lp/default_sbl_gpmc_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)
