Bin,

Hi Frank,

On Ubuntu PC, command 'sudo apt update && sudo apt install dfu-util' will install the tool.

Bin,

As online guide descripted, looks like dfu-util is used to download images to SRAM via USB then booting.

There is no flashing work in dfu-util.

Is there any reference tool in U-boot to flash our image to OSPI or EMMC in TI?

BR,

frank

hi Bin,

Looks like the tiboot3.bin generated by Yocto in image deploy is not suitable dfu-util usage.

We weren’t in flash procedure yet.

Just execute the command “sudo dfu-util –R –a bootloader –D tuboot3.bin” only.

And we found that we can’t do following steps as TI website described.

Please help to provide a way to create tiboot3.bin in Yocto.

And please help to describe the cause about issue.

Error is showing as following:

Hi Frank,

The instruction I provided mentions the flashing u-boot images are built with different defconfig, did you follow it?

First set of images to boot using USB-DFU:

1.  These files may be built using the Build U-Boot instructions with “am62x_evm_r5_usbdfu_defconfig” and  “am62x_evm_a53_defconfig”.
