Hello,
We have configure the spi0 with bellow configuration, and we are able to get signature from qca7000 module.
The changes have added on k3-am642-sk.dtb file.
main_spi0_pins_default: main-spi0-pins-default {
pinctrl-single,pins = <
AM64X_IOPAD(0x0210, PIN_OUTPUT, 0) /* (D13) SPI0_CLK */
AM64X_IOPAD(0x0208, PIN_OUTPUT, 0) /* (D12) SPI0_CS0 */
AM64X_IOPAD(0x0214, PIN_OUTPUT, 0) /* (A13) SPI0_D0 */
AM64X_IOPAD(0x0218, PIN_INPUT, 0) /* (A14) SPI0_D1 */
AM64X_IOPAD(0x009c, PIN_INPUT_PULLDOWN, 7) /* (Y18) GPMC0_WAIT1.GPIO0_38 */
>;
};
&main_spi0 {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&main_spi0_pins_default>;
ti,pindir-d0-out-d1-in;
qca7000: ethernet@0 {
compatible = "qca,qca7000";
reg = <0x0>;
interrupt-parent = <&main_gpio0>; /* GPIO Bank 3 */
interrupts = <38 IRQ_TYPE_EDGE_RISING>; /* Index: 25, rising edge */
spi-cpha; /* SPI mode: CPHA=1 */
spi-cpol; /* SPI mode: CPOL=1 */
spi-max-frequency = <8000000>; /* freq: 8 MHz */
local-mac-address = [ A0 B0 C0 D0 E0 F0 ];
};
};
When we are configure for the spi1 but we are not able to get signature.
main_spi1_pins_default: main-spi1-pins-default {
pinctrl-single,pins = <
AM64X_IOPAD(0x0224, PIN_OUTPUT, 0) /* (C14) SPI1_CLK */
AM64X_IOPAD(0x0220, PIN_OUTPUT, 0) /* (D14) SPI1_CS1 */
AM64X_IOPAD(0x0228, PIN_OUTPUT, 0) /* (B15) SPI1_D0 */
AM64X_IOPAD(0x022c, PIN_INPUT, 0) /* (A15) SPI1_D1 */
AM64X_IOPAD(0x00a4, PIN_INPUT_PULLDOWN, 7) /* (N17) GPMC0_DIR.GPIO0_40 */
>;
};
&main_spi1 {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&main_spi1_pins_default>;
ti,pindir-d0-out-d1-in = <1>;
qca7000: ethernet@0 {
compatible = "qca,qca7000";
reg = <0x0>;
interrupt-parent = <&main_gpio0>; /* GPIO Bank 3 */
interrupts = <40 IRQ_TYPE_EDGE_RISING>; /* Index: 25, rising edge */
spi-cpha; /* SPI mode: CPHA=1 */
spi-cpol; /* SPI mode: CPOL=1 */
spi-max-frequency = <8000000>; /* freq: 8 MHz */
local-mac-address = [ A0 B0 C0 D0 E0 F0 ];
};
};
Could you please help on that..!
Regard,
Dharmik
