1.3.2. Boot Duration Measurements
This section presents various Boot time measurements taken on the Cyclone V Development Kit. Only Boot ROM and Preloader are measured.
The measurements are done with the following setup:
- SoC EDS 14.1b182: for GHRD & Preloader
- Cyclone V Development Kit rev D
- Kingston 4GB Class 10 SD card
- 512 MB Micron QSPI
- Preloader size = 38,548 bytes
- U-boot size = 238,316 bytes
Note: All durations are in milliseconds.
