I update the latest frameware into nucleo f411re. I find that when uploading the Espruino into the board, it has no respronse. How to fix it ?

Hi - you mean you updated the Nucleo's bootloader firmware?

If so, it's a bug we know about: espruino/Espruino#742

Basically ST added some check that stops you uploading perfectly valid firmwares to the board. I was hoping they'd fix it but it seems not, and we'll have to change Espruino to work around it :(

I'd either downgrade the bootloader firmware, or install the ST-Link utilities and use those - which should flash the firmware on regardless.
