Compatibility BB blue vs Black + robotics cape

[ith...@gmail.com]

Hi. Can I just take an sdcard from bb blue, put it into black + cape and expect it to work? If not, what should I change?

There is a special dtb you need to load for the black+cape
combination, but yes same image will boot..

Should I just proceed as with a raw BB black, no need to remove some dtd special for BB blue?

I did this:

$ sudo /usr/bin/configure_robotics_dt

/usr/bin/configure_robotics_dt: line 11: warning: command substitution: ignored null byte in input
Using am335x-boneblack-wireless-roboticscape.dtb
making backup copy of /boot/uEnv.txt
Using previously listed kernel 4.14.71-ti-r80
Robotics Cape Device Tree Configured and Installed

Restarted or not, there are errors in example applications like:

ERROR: in init_led, failed to open LED file handle: No such file or directory

serial ports do not work, no 6V with rc_test_servos etc.

Works after another reboot.
