beaglebone black adc“in_voltageX_raw':资源暂时不可用”

如何解决beaglebone black adc“in_voltageX_raw':资源暂时不可用”

我很难从 bbb 上的模拟输入中获取读数。

cat /sys/bus/iio/devices/iio:device0/in_voltage5_raw cat: '/sys/bus/iio/devices/iio:device0/in_voltage5_raw': 资源暂时不可用

有人有想法吗?

谢谢 鞠

解决方法

我认为您使用的是 SD 卡启动,对吗?

...

好吧,您在 SD 卡和 eMMC 上有两个不同版本的 uboot。 eMMC 在启动时保持在 SD 卡上以供 uboot 使用。

如果可以并且不介意丢失 eMMC 上的数据,您可以擦除 eMMC 中的数据或在通电约 5 秒钟的同时按下 S2/Boot 按钮。

另外,我认为芯片上的 ADC 线路在启动时已经通电了。我认为您不需要 ADC 的叠加层。如果这对您有用,请告诉我。
