The system heap was 192K at 13:56 when I put cards in each of the slots in
the reader and is still 192K at 17:00.
So the fully populated card reader did NOT cause the system heap to
increase.
I've now dismounted and removed the cards but left the empty reader
connected.
At 17:25 the system heap has already grown to 200K.
I removed the card reader and it has remained at at 200K
Conclusion: On my BB-xm rev.B ROS 2.18 ARMini support SP3
The growth in the system heap only occurs when an empty memory card reader
is connected. If the card reader is fully populated or is not connected
there is no increase. (I have not tried just having one card slot in the
reader with a memory card in it)
Hope this helps the programmers to trace the bit of code where the memory
leak is ocurring.
