Overview of clocks

Clock generators on the V2M‑Juno motherboard generate clocks for the internal blocks in the Juno Arm® Development Platform SoC, the internal blocks in the IOFPGA, and the peripherals on the board.

During powerup or reset, internal EEPROMs in the clock generators configure the generators to the correct operational clock frequencies. The board.txt file also defines these default clock frequencies. You can change the operational clock frequencies by modifying the configuration board.txt file.


Arm recommends that you operate the V2M‑Juno motherboard at the default clock frequencies.
