PCIe support on ArmStoneA9

naitec · May 21st 2019

Hello

I found this on armstonea9qdl.dtsi

#if 0 // not tested
&pcie {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_pcie>;
disable-gpio = <&gpio5 15 GPIO_ACTIVE_LOW>;
power-on-gpio = <&gpio6 16 GPIO_ACTIVE_LOW>;
reset-gpio = <&gpio5 17 GPIO_ACTIVE_LOW>;
status = "okay";
};
#endif

I would like to know if ArmStoneA9 has PCIe support or not.

Thanks

Hello,

in the latest fsimx6-V3.1 release we didn´t test the PCIe interface. That´s why it´s commented out. Internally we have tested PCIe with a newer kernel version and it works fine. I would say it also should work with fsimx6-V3.1 release.

To activate PCIe you have to do the following steps:

Activate &pcie node in device tree
Activate CONFIG_PCI and PCI_IMX6 in kernel menuconfig
Rebuild kernel

Thanks for your response, fs-support.

When will the new kernel version be available?

I would not like to spend a lot of time with an untested version.

Thanks in advanced.

The new kernel version should be available in the next 2 months.

I assume that it also work with the current release because we don´t have to do any HW/SW modifications.
