如何解决AP6525 wifi与bt无法启动的问题？

如题。我板子上的电路与开发板中的基本一样。只是把wlan_regon和bt_regon两个管脚从IO扩展芯片TCA6424的P00，P04脚改成了P16和P17脚。管脚号在设备树中已经修改如下。
            wlan:wlan {
                     compatible = "allwinner,sunxi-wlan";
                     clocks       = <&clk_losc_out>;
                     pinctrl-0    = <&clk_losc_pins_a>;
                     pinctrl-names = "default";
                     wlan_busnum = <0x1>;
                     wlan_power;
                     wlan_io_regulator;
                     wlan_regon = <&gpio_ext 16 0>;
                     wlan_hostwake = <&pio PG 14 1 0xffffffff 0xffffffff 0>;
                     chip_en;
                     power_en;
                     status       = "okay";
            };

            bt:bt {
                     compatible = "allwinner,sunxi-bt";
                     clocks       = <&clk_losc_out>;
                     bt_power;
                     bt_io_regulator;
                     bt_rst_n    = <&gpio_ext 17 0>;
                     status       = "okay";
            };

            btlpm:btlpm {
                     compatible  = "allwinner,sunxi-btlpm";
                     uart_index  = <0x1>;
                     bt_wake    = <&pio PG 13 1 0xffffffff 0xffffffff 1>;
                     bt_hostwake = <&pio PG 12 1 0xffffffff 0xffffffff 0>;
                     status    = "okay";
            };

但是模块无法正常工作。请问如何解决这个问题。
