Hi, I’ve encountered a potential issue when running different base demos from the SD card image.
After I run the board_btns_leds demo under the base/board directory (which works fine), if I then run the 5_base_overlay_video demo under getting_started, the board often crashes. The “down” LED also turns off and stops functioning.
I used the official PYNQ-Z2 board and the official PYNQ-Z2 image version 3.0.1 for testing, and the issue consistently occurs. I also tested this using my own custom board (a PYNQ-Z1 clone) running the PYNQ-Z1 image version 3.0.1, and the same issue happens.
I’m not sure if this is a common problem. I tried pressing the stop button after running the LED demo before launching the video demo, and sometimes this allows the video demo to run successfully. However, if I then try to go back and run the LED demo again, the board crashes once more, and the “down” LED remains off.
Has anyone else experienced this kind of issue?

你好，我在使用 SD 卡镜像运行不同 base 演示程序时遇到了一个可能的问题。
当我运行 base/board 目录下的 board_btns_leds 演示（可以正常工作）之后，再去运行 getting_started 目录下的 5_base_overlay_video 演示时，开发板经常会死机，同时 “down” 指示灯也会熄灭且失效。
我使用的是官方的 PYNQ-Z2 开发板和官方提供的 PYNQ-Z2 镜像（版本 3.0.1）进行测试，问题是可以稳定复现的。我还用我自制的 PYNQ-Z1 克隆板搭配 PYNQ-Z1 的 3.0.1 镜像测试过，也会出现相同的问题。
我不确定这是不是一个常见的问题。我尝试在运行完 LED 演示后点击停止按钮再去运行 video 演示，有时候这样是可以正常运行的。但如果我再次返回去运行 LED 演示，系统又会死机，“down” 灯也再次熄灭。
有没有其他人也遇到过类似的问题？
