Beagle Bone Black GPIO与设备树覆盖后无法控制我的GPIO

我正在使用4.14.40-ti-r50内核和[U-Boot 2018.03-00002-gac9cce7c6a]的U-Boot版本运行Debian Stretch
我遇到的问题是我在更新设备树覆盖后无法控制我的GPIO。
我根据此pdf的第7页更新了DTO。
Skywire BeagleBone Black Cape可以按照预期连接到互联网，我现在无法控制任何其他GPIO。
我试图在/ sys / classes / gpio设置下手动控制GPIO的终端，它只显示2个甚至没有在BBB引脚图上的gpios，当我尝试将正确的GPIO导出到这个列表中时，我
能够更改值，但不会通过GPIO发送信号。
我甚至检查GPIO是否是MUX，但是它们没有显示为可用。
我正在考虑当我根据导致此问题的斗篷的用户手册更新设备树覆盖时。
我需要GPIO连接传感器和LED但不控制GPIO，我的程序将无法正常工作。
如果您需要任何其他日志文件，请告诉我。



以下为原文

        I am running Debian Stretch with the 4.14.40-ti-r50 kernel and a U-Boot version of [U-Boot 2018.03-00002-gac9cce7c6a]
The problem that I am running into is that I am unable to control my GPIO’s after updating my Device Tree Overlay.  I updated the DTO as per page 7 of this pdf.
The Skywire BeagleBone Black Cape is able to connect to the internet as intended, I just cannot control any of the other GPIO’s now.  I have tried to manually controll the GPIO’s through terminal under the /sys/classes/gpio settings and it only displays 2 gpios that are not even on the BBB pin out diagram, and when I try to export the correct GPIO’s into this list, I am able to change the values but it will not send the signal over the GPIO.  I even check to see if the GPIO’s are MUX’d, but non of them show as available. I am thinking it was when I updated the device tree overlay as per the user manual for the cape that caused this issue.  I am needing the GPIOs to connect to sensors and LEDs but without control of the GPIOs, my program won’t work.
If you need any other log files, please let me know.
