esptool: Permission denied
Posted: Thu Apr 20, 2017 12:40 pmHello.
I'm trying to compile a project with esp_iot_sdk 1.30
but I get "esptool: Permission denied" every time I hit make.
I'm using esp-open sdk.
I downloaded esptool from here : http://filez.zoobab.com/esp8266/esptool-0.0.2.zip (according to step 2 here: https://github.com/cnlohr/ws2812esp8266) and made that my FW_TOOL
I'm tying to compile this project : https://github.com/pulkin/esp8266-injection-example.
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
Please help!
Here is my Makefile:
