imx93 wifi ap6212 debug

[5454ty]

HI,

    My platform is imx93 evk

   SDK VERSION ：6.1.22-2.0.0

  HI，

      I am debugging the wifi modules  .It is ap6212

      my dts is modified as follows:

 My critical log is as follows:

我的DTS如附件所示

如果你使用GPIO3_IO26作为中断引脚，中断配置应该是这样。

[5454ty]

刘工，

     我的其实是

我的中断脚其实是这个，gpio2 9

但是还是报这个错误，能否再看看

[5454ty]

刘工，您好

 上回那个错误解决了，现在变成了BRCM驱动报错了，你能否看看

我贴上我的关键日志

MMC2识别了SDIO卡，但是报下面的错误

是SDK的驱动太旧了嘛

[Zhiming_Liu]

Hi

从下面网站下载brcmfmac43430a0-sdio.bin，放到文件系统对应的位置，可能是/lib/firmware/brcm/brcmfmac43430-sdio.bin

https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/brcm

报错变了，还有得看嘛

我其实自己创建了brcm目录，把对应文件放进去了，可是还是报上面的错误

[Zhiming_Liu]

如果你的引脚连接的是芯片pad上的GPIO2_IO9，需要加在pinctrl节点里。

	pinctrl_usdhc3_wlan: usdhc3wlangrp {
		fsl,pins = <
			MX93_PAD_CCM_CLKO1__GPIO3_IO26		0x31e
          MX93_PAD_GPIO_IO09__GPIO2_IO09          0x31e
		>;
	};

还是这个错误，我增加了那行

[Zhiming_Liu]

Hi

GPIO3_IO26设置pinctrl了吗？

Best Regards
Zhiming

[5454ty]

您好，

设置PINCTRL什么意思，还不太懂，不好意思
