Hello,
this is my first message on this forum and I hope somebody can help me.
I am using a beagle bone Green with ArchLinux Arm and want to use ePWM2.
I started with Arch version 4.09 and the PWM was available after echoing BB_PWM2_00A0.dtbo to /sys/devices/platform/bone_capemgr/slots. Then the PWM worked fine. To be able to install other packages (base-devel) it was required to upgrade by pacman -Syu. Now I am in version 4.15.4. As now no directory bone_capemgr exist I have no idea how to insert the kernel overlay. I tried it as uboot overlay but also no success. All I want to achieve is changing the pinmux in control module $44E10000 offset conf_gpmc_ad9 $0824 from $0027 to $0004 to connect ball T10 = P8-13 from GPIO0[23] to EHRPWM2B. First I tried it with MMap in a freepascal application, but I keep reading back $27 after writing $04. It looks like this area is protected by the kernel. Unfortunately I have no knowledge to write and try an application in kernel mode.
After half a week of trying to solve this I am out of options. I hope you can help me.
Thanks, Anthony
