publish error in "end()" function
LucasMahieu opened this issue · comments
When I want to publish a value, the function "end" is called. All time this function is used, I can see the program into Hard_Fault_handler.
This bug is due to the definition of the function end into my linker script. I think that this name is used to manage the head. So We should rename this function.
Good catch Lucas
Could you post here the contents of your linker scripts ?
for sure, here it is :
