仿照微雪tiny，做了一个rp2040的系统。布局重新弄了。正常焊接并检查引脚没有问题后，和微雪tiny一样上电。电脑弹出了大容量USB设备的提示，我把官方uf2固件拖进去后，USB设备消失。正常pico到现在开thonny就能看到py版本，但是我开thonny却看到了：
Couldn't find the device automatically.
Check the connection (making sure the device is not in bootloader mode) or choose
"Configure interpreter" in the interpreter menu (bottom-right corner of the window)
to select specific port or another interpreter.
Process ended with exit code None.
而且设备管理器也没有扫描到rp2040。请问这是什么情况？
