DE1, Altera Monitor Program 15.1 and SD Card Boot issue

Honored Contributor II



We are developing a baremeral application on DE1-SOC board using HPS only and Altera Monitor Program 15.1. 

The project has to access SD Card and it works well so far.  


But my problem is that, whenever I compile and try load the project into board, it gives error about "linux booting.." if our empty SDCard is plugged into MMC socket. 

And I had to unplug the card for proper project loading. This is annoying, I don't want to remove sdcard from the slot each time I need to recompile and load the project. 


How to disable sdcard linux boot option at power up?
