The image uses the 32 bit platform.
I just thought that as I have a 64 bit board I should use it, it also allows the use of extended memory.
The Jmri just refuses to select GPIO and states this error iscexpected when not running on a pi.
As I said a bit odd, I can select simulator so Mt pi gpio can be included in the sensor tables and scripts.? I won't let this beat me ...
