I have a spiff file that uploads fine using a regular esp32, but when I try on the esp32-32, with a fresh installation, I get:

esptool.py v3.0-dev Serial port COM3 Connecting....

A fatal error occurred: This chip is ESP32-S2 not ESP32. Wrong --chip argument? SPIFFS Upload failed!

Any ideas??

Thanks

  • Arduino does it for you, but I also tried: esptool.py -chip esp32s2 -port COM3 -baud 115200 write_flash -z ox110000 filename.spiffs.bin Dec 9, 2020 at 15:19
  • maybe you have to specify the S2 for the spiffs tool

    Actually we are at v3.1, cannot you upgrade to it? Maybe it's a bug.. Jul 28, 2021 at 18:55

Is the missing double dash?

esptool.py --chip esp32s2 --port COM3 --baud 115200 write_flash -z 0x110000 filename.spiffs.bin
