LP-AM243: MCU bring up

Hi all TI expert,

I have a problem on LP-243 bring up,

I followed the document step, try to bring up the develop board, link like below,

my environment:

Platform: Windows

SDK: mcu_plus_sdk_am243x_09_00_00_30

In the dfu-util step, I got problem, my dfu-util version is dfu-util 0.8

then in

In the zadig, even I list all device in the Options, I can't found the AM64x DFU this device,

I also found another topic discuss about the AM6442 dfu issue.

In this case, into SDK folder, /tools/boot/usb_dfu_uniflash.py, use python to execute this file,

use the command like below,

python usb_dfu_uniflash.py --cfg=sbl_prebuilt\am64x-evm\default_dfu_ospi.cfg

Because we used different develop board, so made some change, the correct command like below,

python usb_dfu_uniflash.py --cfg=sbl_prebuilt\am243x-lp\default_dfu_ospi.cfg

File not found, then I found in the default_dfu_ospi.cfg file, 31 lines, indicate to a not exist file,

ipc_notify_echo_system.release.appimage_xip

this file not exist in the SDK folder,

How could I go to next step?
