Description:

Hello.
I need help.
I have WROOM-32 ESP32 module.
In folder of my ino-project I created folder ‘data’ and put into it some files: css, html, txt by ESP32 Sketch Data Upload (https://github.com/me-no-dev/arduino-esp32fs-plugin), I have uploaded them successfully to my module.
When I try to read file from SPIFFS (previously mounted SPIFFS, of course) (latest arduino-esp32, https://github.com/espressif/arduino-esp32), listDir(SPIFFS, "/", 0) - OK; but while I use readFile(SPIFFS, "/style.css"); there is some trash, but no correct data. When I use write and read file, which was NOT uploaded by ESP32 Sketch Data Upload, it is OK.

By the way, I noticed string: flash read err, 1000 ets_main.c 371

Any ideas?
Thanks.
