Hi, Sir, 

I'm tring to change MMCSD booting to OSPI flash booting, 

So I modified j721e_evm_r5_defconfig as following

========================================

#CONFIG_ENV_IS_IN_MMC=y
CONFIG_ENV_IS_IN_SPI_FLASH=y

=========================================

But loading uBoot-Env fail and the log displayed "loading rproc not supportted".  

Please help to clarify.

Br,

KS

    Hi,

    The loading of remoteproc binaries is supported only when booting from SD card.

    Is the boot failing in the u-boot after these messages? I would expect that the boot succeeds. Please clarify.

    Please clarify the same.

    Regards

    Hi,

    1.Loading Envoriment fail cause that boot time is too long. 

    Answer: I'm not sure if this is the reason for the longer boot time. But please check below answer to question #2.

    2.Why OSPI reading uBoot-Env fail in MCUR5F SPL? 

    Answer: Reading the environment while in OSPI boot mode is not fully supported.

    3.Will TI support the loading of remoteproc binaries form OSPI flash in future? 

    Answer: The short answer is that it is not directly supported. However, support exists if you are using UBIFS and have the remoteproc binaries in that.

    4.Is the loading of remoteproc binaries necessary when mcu r5f booting time?

    Answer: No, it is not necessary for MCU R5F booting or for the subsequent booting of Linux.

    Could you please explain the usecase and also the targets that you have in mind?

    We are going to introduce a newer boot method that uses OSPI in combination with the SBL boot loader. If we understand your usecase better, then we can go ahead and provide you further details.

    Regards
