hi, can anyone tell me, waht kind of error this is? when i try to upload an app to the core, the transmission stucks at 15% and i get this error message.

i already managed to upload an app before, so i wonder why this doesn´t work anymore.

thanks

Upgrading to the latest boot loader and MIOSStudio solved that issue for me. HTH :slight_smile:
