Tool/software:

Hi,

We would like to run both Linux and the MCU M4F binary at boot time from eMMC.

Could you please share the method to achieve this?

Thank you,

Hello Gopal,

Please help us understand. Are you asking about whether you can keep your Linux filesystem and boot files on the eMMC instead of on an SD card?

Or are you asking something like whether you can boot the M4F core earlier in the boot process than with the Linux remoteproc driver?

Regards,

Nick

Hi Nick,

Thank you for your support.

We are currently following the instructions provided in this

https://software-dl.ti.com/mcu-plus-sdk/esd/AM62X/latest/exports/docs/api_guide_am62x/GETTING_STARTED_FLASH.html
https://software-dl.ti.com/mcu-plus-sdk/esd/AM62X/latest/exports/docs/api_guide_am62x/SBL_BOOTING_LINUX_EMMC.html

While the system is booting successfully and the M4F is starting up earlier to Linux with the IPC example, it is currently booting Linux from the SD card.

Our goal is to have both Linux (file system and kernel) and the M4F binary stored entirely on the eMMC rather than the SD card.

Could you kindly guide us on the necessary steps to achieve this?

Regards,
Gopal Sharma

Please flash the filesystem to the eMMC as per the following guide:

https://dev.ti.com/tirex/explore/node?node=A__AdNWBqCVds4ZSqU9osT1tQ__AM62-ACADEMY__uiYMDcq__LATEST

If using SBL_EMMC_LINUX then the M4F binary or any other core binary is already booted from the eMMC only.
