Hi,
Sorry sure I done an mistake here :
//ADD - EMAC Clock Register defaut value 0x58000 - need reset bit 16 (power up)
emac_clk_reg_rst: reset@01c30000 {
#reset-cells = <1>;
compatible = "allwinner,sun6i-a31-ahb1-reset";
reg = <0x01c30000 0x4>;
};
please remplace it by
//ADD - EMAC Clock Register defaut value 0x58000 - need reset bit 16 (power up)
emac_clk_reg_rst: reset@01c00030 {
#reset-cells = <1>;
compatible = "allwinner,sun6i-a31-ahb1-reset";
reg = <0x01c00030 0x4>;
};
I can find some operation equivalent about what I propose in "Loboris kernel
3.4" :
In sunxi_geth.h
#define SYS_CTL_BASE 0x01c00000
#define GETH_CLK_REG 0x0030
#define GETH_CLK_GPIT 0x00000004
In sunxi_geth.c
value = readl(priv->geth_extclk + GETH_CLK_REG);
if (priv->phy_ext == INT_PHY) {
value |= (1 << 15);
value &= ~(1 << 16);
value |= (3 << 17);
} else {
value &= ~(1 << 15);
value |= (1 << 16);
}
writel(value, priv->geth_extclk + GETH_CLK_REG);
I can't find the driver dwmac or stmmac file, code area where is accessing REG
at low level. No trace in uboot? Any idea about A31 Hummingbird openwrt working
source?
the dmesg log of A31 Hummingbird openwrt :
