使用imx6ull + AP6212, 启动的时候可以看到mmc1相关说明:

原理图如下:
大伙可以帮忙看看这个是啥原因,为何出现前面的“ HT Avail timeout (1000000): clkctl 0x50” ? 该如何解决或者调查呢? 谢谢各位。

这种sdio读写tf卡正常吗?

把时钟降低到 5Mhz左右, 接逻辑分析仪, 看是不是每根信号线时序都是正常的.

你的LPO管脚是否提供了32.768Khz的时钟?这个非常重要

你需要外接32K有源信号,内部的不OK

请教一下,使用imx6ull自己生的PMW生成32K的波,应该也是可以的吧?
现在使用PWM用逻辑分析仪可以看到32K的方波(50%占空比)输入给AP6212,但是还是不行
还尝试了使用Arduino生成32K的CLK(PWM,50%占空比)也不行。这可能是啥原因呢?
出现的log还是前面的那个Timeout
