Tool/software:

Hi ,

I have a custom build for EMMC  , which is  working fine on the board , 

when i try to send tiboot3 via DFU  its getting reset error , so i add below config in k3r5.conf as per SDK reference . 

UBOOT_MACHINE = "am62x_evm_r5_defconfig am62x_evm_r5_usbdfu_defconfig"
 

After that try to boot , tiboot3 error reset error goes off and its reset at tispl.bin ,is any  another a53 config should i add  , attaching boot log below

    Hi RJ,

    I know little about Yocto, but,

        UBOOT_MACHINE = "am62x_evm_r5_defconfig am62x_evm_r5_usbdfu_defconfig"

    this doesn't seem correct for U-Boot 2023.04, it should be only with "am62x_evm_r5_usbdfu_defconfig", without "am62x_evm_r5_defconfig".

        U-Boot SPL 2023.04-ti-g2bedcd265ca6 (Dec 07 2024 - 07:04:35 +0000)
        SYSFW ABI: 4.0 (firmware rev 0x000a '10.1.8--v10.01.08 (Fiery Fox)')

    this two lines of the messages do not match in Processor SDK versions.

    U-Boot version 2023.04 is used in Processor SDK v9.x, while SYSFW version 10.1.8 is used in Processor SDK v10.1, they don't typically come together. I am not sure if you intended to mix both together.
