nsh: i2c: command not found

Hi everyone! I've built an application that sends i2c set/get commands to NuttX using the system() function in a loop that breaks after a timer runs out. After some i2c requests, NuttX prompts the message 'nsh: i2c: command not found' and the only way to solve it is rebooting the ESP32. This i

Run app when device starts

Hello! I've built an application to run on NuttX and I'd like to know if it's possible to make it start when the device starts so I don't have to connect into the console to run it.

Hi Greg! Yes, if I use #include this problem is solved, but then the code loses the reference to that specific struct causing another error. And how exactly "the file does not exist"? I can open it and it is at the nuttx repo, I shared it's link. From: Gregory

I use those arrays to read the request and send the response, there is no stack overflow error. I've defined a IP value inside the server file (#define) and it worked as intended, but I want to be able to read the IP from Kconfig instead of having it in the server file, I'll be looking for a wa

Maybe I don't have to transfer the file to the tmp folder. I think the folder the app is reading is not the app folder but the root, so it won't find the file. Is it possible to access the built-in apps folder on NuttX? So I can make the app to read its folder.
