I am connecting my STM32MP257F-EV1 board to rpi Hailo 8 board via Mini Pcie to M.2 key M adapter. The board is not getting detected even though clock and reset signals are coming properly.
I am using the stm32mp257f-ev1.dts (default device tree) and also sharing my device tree pci node below
&pcie_rc {
pinctrl-names = "default", "sleep";
pinctrl-0 = <&pcie_init_pins_a>;
pinctrl-1 = <&pcie_sleep_pins_a>;
reset-gpios = <&gpioj 8 GPIO_ACTIVE_LOW>;
wakeup-source;
wake-gpios = <&gpioh 5 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>;
status = "okay";
};
I am getting this error as given below:-

My question is
What can be the reason for this error?
What changes can i do so that the Hailo 8 board gets detected in lspci command?
