WebThe ways to disable the REF_CLK signal can be: Disable or power down the crystal oscillator (as the case b in the picture). Force the PHY device in reset status (as the case a in the picture). This could fail for some PHY device (i.e. it … WebThe ETH_CLK pad which provide a clock to the PHY and The ETH_REF_CLK pad or ETH_CLK125 pad to get reference clock from the PHY. Depending on the configuration of your design, you have to configure the device tree, then the ethernet driver controls the clock configuration via the below registers.
WebThis signal indicates a 64-bit user data (per lane) at rxlink_clk clock rate, where 8 octets are packed into a 64-bit data width per lane. The data format is big endian. If L=1 and M*S*N*WIDTH_MULP=64, the first octet is located at bit [63:56], followed by bit [55:48], and the last octet is bit [7:0]. WebMay 29, 2024 · RK3399 linux内核启动卡死.

WebThe new code also tries to get "clk_mac_ref" and "clk_mac_refout" when the PHY is not configured as PHY_INTERFACE_MODE_RMII to keep the code simple. This is possible since we use devm_clk_get_optional() for the clock lookup anyways. WebResolution: Verify the create_clock command was called to create the clock object before it is referenced.
