A dfu error occurs when downloading an image
I am currently developing using the STM32MP157FAD. And I want to create a distribution image and download the image using STM32CubeProgrammer.
However, while downloading the image, the following error message is displayed in the log of STM32CubeProgrammer.
15:34:17:270 : DFU status = 0
15:34:17:270 : DFU State = 5

I would be grateful if you could teach me how to solve this problem.
