ISSUES TRYING TO USE USING ESP8266_RTOS_SDK for ESP8285
Posted: Sat Jul 23, 2022 1:29 pmI am trying to run code generated via the ESP8266 RTOS SDK on an ESP8285.
I am using a simple "Hello World" example. The code runs using the Arduino IDE (1.8.19) on ubuntu linux.
Using the ESP8266 SDK on ubuntu, I get a "csum err"
Arduino IDE Code:
ESP SDK code (from ESP8266_RTOS_SDK/examples/get-started/hello_world)
ESP8266 SDK on Ubuntu Linux : Hello world downloads, but get the following on the console when it tries to start.
