HI all
I'm trying to get a custom board, based on iMX6Q SoC, to bring up the PCIe link connected to a BCM4356.
my buid environment is Android5.1.1_2.1.0-ga
and at kernel menuconfig . i set
BUS support -----> [*]PCI support
------>PCI host controller drive
------>[*]Freescale i.MX6 PCIe controller.
Device Drivers---->[*]Network device support
------->[*]Wireless LAN
-------><*> Broadcom FullMAC wireless cards support
(/system/etc/firmware/bcm/fw_bcmdhd.bin) Firmware path
(/system/etc/firmware/bcm/nvram.txt) NVRAM path
Enable Chip interface (PCIe bus interface support)
and at kernel device tree
i add
pinctrl_pcie: pciegrp {
fsl,pins = <
MX6QDL_PAD_KEY_ROW1__GPIO4_IO09 0x1b0b0
MX6QDL_PAD_KEY_COL2__GPIO4_IO10 0x1b0b0
>;
};
&pcie {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_pcie>;
//disable-gpio = <&gpio5 15 GPIO_ACTIVE_LOW>; //hw alway-high
power-on-gpio = <&gpio4 10 GPIO_ACTIVE_LOW>;
reset-gpio = <&gpio4 9 GPIO_ACTIVE_LOW>;
status = "okay";
};
but the log show imx6q-pcie : probe failed with error -16
No Broadcom PCI device enumerated!
Can somebody help me??
