esptool: Permission denied

Postby davidthe16 » Wed Apr 26, 2017 2:17 am

I'm trying to compile a project with esp_iot_sdk 1.30 for a school POC project.
but I get `esptool: Permission denied` every time I do `make`.

Code: Select all

david@david-VirtualBox:~/myprojects/esp8266-injection-example$ ls -al

There is no global variable `ESPTOOL`, or `FW_TOOL`:

Code: Select all

 david@david-VirtualBox:~/myprojects/esp8266-injection-example$ echo $FW_TOOL
    david@david-VirtualBox:~/myprojects/esp8266-injection-example$ echo $ESPTOOL

I'm using esp-open sdk.
I downloaded esptool from here : (according to step 2 here: and made that my FW_TOOL

I'm tying to compile this project : for the POC project.

I tried this solution but it didn't work (I tried to do it for the esptool folder in esp-open-sdk, and for the esptool folder I downloaded above) viewtopic.php?p=12465

I tried to do sudo chmod 777 esptool, for both esptool folders

And nothing works for me

NOTE: If I do ` chip_id` I do get a response.
Also I was able to burn `blinky` demo with the new SDK (that came with esp-open-sdk). So it looks like there is a problem with this sdk specificly...

I am also part of `dialout` group

Did you try executing the esptool from somewhere else? Like from your desktop or something?
