4.2 Timing Tuning
After power up, the Xccela ZedBoard runs at 25 MHz SDR mode by default. The system enters 25 MHz
SDR mode as well once RESET is executed or the tuning operation is unsuccessful.
The
TUNING [mode+freq] [sectornum]
command tunes DUT with the expected mode (SDR or DDR)
and frequency for the SPI controller with the following options:
•
S50: SDR 50MHz
•
D50: DDR 50MHz
•
S133: SDR 133MHz
•
D133: DDR 133MHz
•
S166: SDR 166MHz
•
D166: DDR 166MHz
•
D200: DDR 200MHz
Below is the TDP used for the Xccela ZedBoard tool:
