#65095 Hello.
I'm trying to compile a project with esp_iot_sdk 1.30
but I get "esptool: Permission denied" every time I hit build.

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 :

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 :( :evil:

Please help!

Here is my Makefile:
