Tool/software:
Hi TI Experts，I get something wrong when flash to eMMC by DFU.
My operation is as follows
1：Reference Documentation
2：SDK Ver
ti-processor-sdk-linux-edgeai-am62a-evm-10_01_00_05
3.Download necessary software
git clone https://git.ti.com/git/processor-sdk/uboot-flash-writer.git
git checkout master
sudo apt-get install dfu-util
4.The document says that there should be a DFU_flash folder under the SDK path, but it doesn't exist, so I copied the folder from the uboot-flash-writer path to the SDK path
copy dir /home/lihao/uboot-flash-writer/tools/DFU_flash to /home/lihao/ti-processor-sdk-linux-edgeai-am62a-evm-10_01_00_05/bin
5.add code at /home/lihao/ti-processor-sdk-linux-edgeai-am62a-evm-10_01_00_05/board-support/ti-u-boot-2024.04+git/configs/am62ax_evm_a53_defconfig
CONFIG_BOOTCOMMAND="setenv dfu_alt_info_flashenv uEnv.txt ram 0x82000000 0x10000000; setenv dfu_alt_info ${dfu_alt_info_flashenv}; dfu 0 ram 0; env import -t ${loadaddr} $filesize; run user_commands;"
CONFIG_ENV_IS_NOWHERE=y
CONFIG_ENV_IS_IN_MMC=y
CONFIG_BOOTDELAY=0
6.Change in Rules.make of SDK
UBOOT_MACHINE_R5=am62ax_evm_r5_defconfig am62x_r5_usbdfu.config
7.I want to flash the system to eMMC first, so I skipped the process of generating binary files and used the default binary files
Skip make u-boot_clean, make u-boot
Now enter the path /home/lihao/uboot-flash-writer/tools/DFU_flash
Copy the default tiboot3.bin, tispl.bin, and u-boot.img to the path specified by
/home/lihao/uboot-flash-writer/tools/DFU_flash/bin/am62axx-evm/gp/flash-files.cfg
8.Run the command python3 dfu_flash.py -d am62axx-evm -t gp -c bin/am62axx-evm/gp/flash-files.cfg
The terminal output is as follows
lihao@lihao-B460MAORUSPRO:~/ti-processor-sdk-linux-edgeai-am62a-evm-10_01_00_05/bin/DFU_flash$ python3 dfu_flash.py -d am62axx-evm -t gp -c bin/am62axx-evm/gp/flash-files.cfg

9.It stops here, I don't know what went wrong
The switch status of the development board is as follows, I connected three USB cables: power cable, UART connected to PC, and another data cable connected to PC
