imx6 Android 4.4.3（kernel 3.10.53）支持SDIO接口的wifi吗？

发表于 2015-12-22 18:13

我用正基科技的AP6212 SDIOwifi模块（博通的芯片），提供的驱动版本是“bcmdhd.1.201.59.x.cn-151201”在imx6dl 的Android4.4.3（kernel版本是3.10.53）是怎么都跑步起来……SDIO通信是通的；我都怀疑是3.10,53kernel导致的了；

这个“bus is down”是什么bus？SDIO总线挂了？

楼主你好，在我们官网提供的文档中，你可以看到我们默认的BSP是支持：
Hardware:
• Atheros AR6103 SDIO
card
• Silex AR6233X SDIO card
• Realtek 8723AS SDIO card
Features:
• AP mode
• Wake on Wireless
也就是说SDIO是支持的，你这里遇到的问题应该是wifi移植有问题，导致内核启动不成功。

关于WIFI的移植建议你参考官网BSP。

我现在用的是博通的AP6212；上面导致系统重启的原因可能找到原因了；MMC_CAP_NONREMOVABLE和CONFIG_MMC_UNSAFE_RESUME有关系；但是SDIO的wifi还是不能能用；能把官方最新的BSP PDF发一份连接给我吗？

我的kernel（3.10.53）现在是用博通的sdio wifi模块；不添加“host->mmc->caps |= MMC_CAP_NONREMOVABLE”则导致系统重启，但是可以读取到SDIO wifi网卡的chip ID；但是添加了“host->mmc->caps |= MMC_CAP_NONREMOVABLE”后连sdio wifi 的chip ID都读取不到了；为什么呢？

关注一下，学习学习......不过MMC_CAP_NONREMOVABLE应该是必须有的吧......

已经解决；

贴片的wifi；把sdio总线配置成Non-removable模式；

发表于 2016-3-7 13:59

原因很简单；在DTS总把sdio总线配置成Non-removable模式；就解决了；

我用的是android4.4.2 , linux3.0.35 ，还不是内核树的方式。我已经将其配置成了ESDHC_CD_PERMANENT 模式。我的还是有问题，能否加一下QQ？或者邮箱？
enum cd_types {
ESDHC_CD_NONE,       /* no CD, neither controller nor gpio */
ESDHC_CD_CONTROLLER, /* mmc controller internal CD */
ESDHC_CD_GPIO,       /* external gpio pin for CD */
ESDHC_CD_PERMANENT,    /* no CD, card permanently wired to host */
};

3.0.35的kernel我也没有调过；所以帮不了你什么；

你好，我最近也在imx6q平台上调wifi驱动，用到的是bcm43438的芯片，可否加个好友聊一下:qq1010235261

发表于 2016-4-8 12:18

各位大神，我的 ap6214a （bcm43438）能驱动起来，但网速非常非常差，是什么原因呀，请指导，（wifi信号是没问题的，其它wifi设备都正常的）
