On Arria10, how to measure time from power-up

On Arria10 that was build in Altera 20.1 environment, I have a startup sequence that includes SPL+UBoot 2020.04 and then after it a VxWorks image: When the VxWorks image loads I want to add a note t...

Hi Yoels,


Hi Yoels,




The booting time for uboot on an Arria 10 SoC FPGA can vary depending on factors such as the U-Boot version, configuration settings, and the specific hardware , booting source such NAND, QSPI, SDcard or etc and peripherals used.


Rough estimation, uboot boots in a matter of seconds, often around 5-10 seconds.


but , the actual boot time can be longer or shorter depending on the complexity of your specific uboot, configuration and the functions needs to perform during booting.


To get a more accurate, measurement can made be using timestamp signals or debugging tools to measure the boot time for your particular setup.


I also need to figure out how to create a time stamp using uboot.

Intel does not support vxwork for this.


Thank you,
