Can't see the file after disconnect and connect NUCLEO-L476RG to PC

Why I can't see the file on NUCLEO-L476RG when I disconnect and connect my NUCLEO to PC? Or even after drag and drop file to NUCLEO-L476RG Drive and refresh the drive I can not see any file except "detail.txt" and "mbed.htm".

Anyone explain me about this.

Thank you.

Because it programs your board with that file. Contrary to the mbed LPC1768, (and LPC11u24), all others targets only appear as mass storage devices, but aren't actually ones. So if you store your bin file on your device, it directly programs the target. Afterwards it is gone.

Accepted Answer

I can't store bin file anymore, because of I'm receiving a message that no more free space remains available on the node virtual storage device (NUCLEO-L476RG). How I can free space on the NUCLEO-L476RG flash memory?

Something is going wrong, since flash memory is automatically completely wiped when you program it. Best bet is to update your ST link firmware to latest version. And make sure you didn't set any jumpers to a wrong state.
