答案对人有帮助，有参考价值 0 1.经过一周的努力的今天终于解决了RK3288安卓系统中打不开WIFI的问题，特意记录一下。 2. 一般拿到板子厂家会提供RK3288的SDK框架包(我的是android8.1)，在这里我附上移植WIFI帮助文档(在最后面) 3. 板级dts文件添加wifi模块需要的代码描述：（至于下面这些代码在哪个文件里面我就不说了，可能你的跟我的不一样，但都是在kernel/arch/arm/boot/bts/里面） wireless-wlan { compatible = "wlan-platdata"; rockchip,grf = <&grf>; wifi_chip_type = "ap6335"; sdio_vref = <1800>; WIFI,host_wake_irq = <&gpio4 30 GPIO_ACTIVE_HIGH>; status = "okay"; }; &sdio0 { status = "okay"; max-frequency = <150000000>; bus-width = <4>; cap-sd-highspeed; cap-sdio-irq; disable-wp; keep-power-in-suspend; mmc-pwrseq = <&sdio_pwrseq>; non-removable; num-slots = <1>; pinctrl-names = "default"; pinctrl-0 = <&sdio0_bus4 &sdio0_cmd &sdio0_clk &sdio0_int>; sd-uhs-sdr104; supports-sdio; }; 4.当然添加上面这两段代码还远远不够，需要看文档继续修改添加，下面的我就不说了，文档找我拿。 5.编译好系统文件和系统镜像后，烧录到板子，发现WIFI一直打不开 6.打不开能怎么办？那只能看RK3288打印了啊（附图）下面都是报错的打印，你可以选择不看，然后我是在这里面找到问题的 [16020.274020] dhd_open: Enter dd6c8800 [16020.274051] [16020.274051] Dongle Host Driver, version 1.579.77.41.2 (r) [16020.274059] wl_android_wifi_on in 1 [16020.274066] wl_android_wifi_on in 2: g_wifi_on=0 [16020.274080] wifi_platform_set_power = 1 [16020.274086] ======== PULL WL_REG_ON(-1) HIGH! ======== [16020.274093] [WLAN_RFKILL]: rockchip_wifi_power: 1 [16020.274101] [WLAN_RFKILL]: wifi turn on power. -1 [16020.575297] sdio_reset_comm(): [16020.588702] mmc_host mmc1: Bus speed (slot 0) = 400000Hz (slot req 400000Hz, actual 400000HZ div = 0) [16020.642667] sdio_read_cis: 2 callbacks suppressed [16020.642693] mmc1: queuing unknown CIS tuple 0x80 (2 bytes) [16020.644206] mmc1: queuing unknown CIS tuple 0x80 (3 bytes) [16020.645743] mmc1: queuing unknown CIS tuple 0x80 (3 bytes) [16020.648662] mmc1: queuing unknown CIS tuple 0x80 (7 bytes) [16020.705084] mmc_host mmc1: Bus speed (slot 0) = 148500000Hz (slot req 150000000Hz, actual 148500000HZ div = 0) [16020.832098] dwmmc_rockchip ff0d0000.dwmmc: Successfully tuned phase to 82 [16020.832526] sdioh_start: set sd_f2_blocksize 256 [16020.833396] [16020.833396] [16020.833396] dhd_bus_devreset: == WLAN ON == [16020.833494] F1 signature read @0x18000000=0x16224335 [16020.835729] F1 signature OK, socitype:0x1 chip:0x4339 rev:0x1 pkg:0x2 [16020.836619] DHD: dongle ram size is set to 786432(orig 786432) at 0x180000 [16020.836793] dhd_conf_read_config: Ignore config file endor/etc/firmware/config.txt [16020.836816] Final fw_path=endor/etc/firmware_bcm4339a0_ag.bin [16020.836822] Final nv_path=endor/etc/firmware/nvram_AP6335.txt [16020.836829] Final clm_path=endor/etc/firmware/clm_bcmdhd.blob [16020.836836] Final conf_path=endor/etc/firmware/config.txt [16020.836841] dhd_set_bus_params: set use_rxchain 0 [16020.836847] dhd_set_bus_params: set txglomsize 36 [16020.837089] dhd_os_open_image: endor/etc/firmware_bcm4339a0_ag.bin (567196 bytes) open success [16020.872375] sdioh_buffer_tofrom_bus: TX FAILED dae38000, addr=0x0a000, pkt_len=1948, ERR=-84 [16020.872394] dhdsdio_membytes: membytes transfer failed [16021.055964] dwmmc_rockchip ff0d0000.dwmmc: Successfully tuned phase to 82 [16021.056330] dhdsdio_download_code_file: error -1 on writing 2048 membytes at 0x0020a000 [16021.056449] _dhdsdio_download_firmware: dongle image file download failed [16021.056659] dhd_bus_devreset Failed to download binary to the dongle [16021.056783] dhd_net_bus_devreset: dhd_bus_devreset: -35 [16021.056841] dhd_wl_ioctl: returning as busstate=0 [16021.056893] dhd_dbg_detach_pkt_monitor, 2204 [16021.056974] dhd_net_bus_devreset: dhd_bus_devreset: -35 [16021.057139] wifi_platform_set_power = 0 [16021.057224] ======== PULL WL_REG_ON(-1) LOW! ======== [16021.057276] [WLAN_RFKILL]: rockchip_wifi_power: 0 [16021.057373] [WLAN_RFKILL]: wifi shut off power.
