Zynq OS - Updating Linux Device Tree To Reflect XPS Hardware System
When I boot into my Linux system, the hardware peripherals work with some clock frequencies, but not others.
When changing the clocking structure for peripherals to values other than the defaults, ensure that the Linux device tree file (DTS) has appropriate entries and values that reflect what has been selected in the XPS system. For example, changing the clock divider structure for the Ethernet GEM peripheral might require the Device Tree settings for these settings to be updated in order for the peripheral to function properly.
