Hi Aliff,

Thank you for your response.

The image you attached doesn't load on my browser for some reason. Anyway, there is no linux kernel and filesystem, I build a project using Uboot 2020.04 that loads a vxWorks image as the operating system (which also doesn't have a filesystem).

I want to know how much time it takes from when the Arria10 starts and gets power until the vxWorks image starts and is ready for the user to do stuff.

I can add relevant code on the vxWorks image and if needed also in the SPL part (the preloader part before the Uboot begins).

For example get timestamps from a relevant clock of the CPU and from there calculate the time difference or with some other method.

Thanks in advance for your help,

Yoels
