The last improvement is more meaningful, you can load the internal memory and SD at the same time. For example:

pyb.usb_mode('VCP+MSC', msc=(pyb.Flash(), pyb.SDCard()))

人去搂空

Thanks for sharing!

如意如意

Thanks a lot, brother. pyb.usb_mode('VCP+MSC', msc=(pyb.Flash(), pyb.SDCard())) can virtualize the SD card into a USB flash drive.
