The last release we did for the BaldEagle platform was back in the 
jethro time frame. Have you tried running things on this platform using 
the jethro combination just to see if you exhibit the same issue? We did 
not observe anything such during our development in the mentioned time 
frame.

Are you experiencing this on multiple target boards or is it a specific 
one that shows such problems?

BR,
Awais
