hi3536+wifi模组ap6356s为什么速度这么慢？

环境：hi3536+Hi3536_SDK_V2.0.6.0+wifi模组ap6356s
问题：
现在移植完毕ap6356s的wifi模块
可以连接ap热点，ping 局域网wifi路由器ip  延时很大，理想情况应该是<1ms，但是实际是几百ms,为什么这么慢，现在想定位是哪里有问题？
示波器测量SDIO_CLK=50MHZ,  DATA0~DATA3都有数据变化，谢谢！



移植驱动包步骤bcmdhd.1.363.59.144.x.cn.tgz
1.关闭Makefile中的#-DENABLE_INSMOD_NO_FW_LOAD

2.添加ap6356s的设备id到driver中
{ SDIO_DEVICE(SDIO_VENDOR_ID_BROADCOM,0x4356) },

3.修改dhd_gpio.c,配置2个管脚,
ap6536s芯片引脚
WIFI_REG_ON                   I                 Low asserting reset for WiFi core (high-out of reset,low-reset)                                GPIO11_2
WL_HOST_WAKE             O                 WLAN to wake-up HOST                                                                                                                                                                                                        GPIO11_3
4.
设置好firmware路径
