Hi there,

Is it possible for you to share the boot-log? Are you trying to disable the ECC?

Hi,

If you want to disable ECC, you can disable it in Qsys/Platform Designer, then the preloader will also disable it.

If you want to enable ECC, BUT disable the ECC checking, I am unsure if this is possible using the BSP Editor to generate, you may need to generate your own custom preloader.

You may read the preloader customization information here, it's helpful:
