Hi Experts,

I checked the boot flow in boot_app_mcu_rtos and found that mcu1_0 directly boot the linux kernel in boot flow of HLOS.

Can boot_app_mcu_rtos boot uboot first, and then use uboot to boot the linux kernel?

Hi Chun,

No, this is not supported. May I ask what you are trying to do/achieve?

If you want Linux boot through U-Boot, you can use Linux R5 SPL instead of boot_app.

Hi Suman,

First, I want to achieve fast CAN response through boot_app_mcu_rtos, and then U-Boot has perfect functions that can be used in debugging, so we want to keep U-Boot.

Will TI implement this boot process?
Or do I have a chance to implement this boot process by modifying boot_app_mcu_rtos?

Regards,

Chun

Hi Chun,

No, TI will not implement this boot process. It is not a standard supported boot flow at all.
