im not using the IDF directly using the flash download tool latest download from site 3.9.3 factory mode

The code is written in on Arduino ESP core 3.0.7 within Arduino it uploads fine I built the spiff file with in this

i took all bins everything uploads fine but if i add or try just the spiffs.bin it fails with com error

I have tried all different baud speeds no luck

If i upload via OTA there is no issue

I am sorry but I am not sure if I can help you if you're using a custom piece of software to do this. If you have Python and pip installed you can download esptool with `pip instal esptool` command and then try to flash the partition that way.

Code: Select all

esptool.py --chip <your chip, e.g. esp32, esp32s3, etc.> -p <PORT> write_flash 0xc90000 <your binary file path .bin>
