ESP-IDF:
$ git describe --tags --dirty
v3.3-beta1-169-g3c94b6e10
I changed the owner for "/opt/esp32/*" - current owner is me/user

In Eclipse (Version: 2018-12 (4.10.0))
I can build project without error (Build Finished. 0 errors, 0 warnings. (took 935ms))
After that in console I printed:

$ make flash

And after the success updating firmware I see the previous firmware. The new firmware don't uploaded.
I try connect dev-board to different USB, reboot my PC - the situation is the same.

Has this board had OTA performed? If so, the bootloader is probably booting to the OTA partition, instead of the factory one you are uploading. Try `make erase_flash` first to clear the partition.

thank you for fast reply

As I see the troubleshooting was from Eclipse.
First trouble - when I press "build" - current version of Eclipse don't save changes
Second trouble - the flashing start work properly after I done "make all", "make flash" in console, after that build and flash under Eclipse start work correct.
