I’m trying to Debug a hello world application on HiFive Unleashed using PlatformIO Core (CLI) tool. I’ve setup the utility using this Wiki:
https://docs.platformio.org/en/latest/core/installation.html#installation
And used these commands to debug the application:
I’m facing a strange error while starting the debug session:
Error: invalid ELF file, only 32bits files are supported
embedded:startup.tcl:486: Error: ** Programming Failed **
Here are the complete verbose logs:
