我想读取dts中定义的某个引脚的寄存器值,确认下其设定成功,步骤如下: 1、dts中定义了 MX6UL_PAD_ENET1_TX_CLK__ENET1_REF_CLK1 0x4001b0a8 2、查看datasheet找到最后一个0x4001b0a8的寄存器地址为Address: 20E_0000h base + 368h offset = 20E_0368h 3、内核中使用readl(ioremap(0x020e0368, 0x1000)...
ENET2_RX_EN is configured as ENET1_REF_CLK_25M and should be an output from the IMX to the PHY at 25MHz. I'm using u-boot ATM, and have the following code: static iomux_v3_cfg_t const fec1_pads[] = { ... MX6_PAD_ENET1_TX_CLK__ENET1_REF_CLK1 | MUX_PAD_CTRL...

IMX6UL的ENET1_TX_CLK__ENET1_REF_CLK引脚和50M外部晶振同时接到SMSC芯片上,默认使用0x4001b0a8的寄存器值时,引脚会输出50M的clk,此时和50M外部晶振有冲突,网卡不能正常工作。现在只能让REF_CLK引脚作为clk in模式使用,使用50M外部晶振作为参考时钟,该引脚的寄存器值如何配置? Labels: i.MX6_All i.MX6UL ...
