Is there good tools (IDE, CLI or IDE addon) to send file via USB port to SPIFSS internal espressif ESP hardware SoC ?


1 Answer 1


The mkspiffs tool creates bin from file system data (or extracts data from bin).

SPIFFS bin is uploaded with esptool over USB or with espota over WiFi. It can be uploaded with the sketch binary in one command.


esptool.py -p /dev/ttyUSB0 write_flash 0x0 sketch.bin 0x300000 spiffs.bin

The IDE plugin adds SPIFFS upload to Arduino IDE Tools menu.
