PROCESSOR-SDK-AM335X: PROFINET stack and heap configuration

Part Number: PROCESSOR-SDK-AM335X

Customer is using AM335x and our Profinet firmware (profinet_slave_RT_MRP).

They have a question regarding STACKSIZE and HEAPSIZE configuration done by Linker GUI.
Please see attached snap shot.

As you can see, customer mistakenly defined STACKSIZE and HEAPSIZE twice and wants to make sure which definition is effective in the codes.

They compare binaries(*.hex) built with below three combination, but all of them are completely the same.
a) STACKSIZE=0x18000
　HEAPSIZE=0x100000

b) STACKSIZE=0x1C000
　HEAPSIZE=0x400

c) Nothing is defined for STACKSIZE and HEAPSIZE

Are these symbols ignored ?

Thanks and regards,
KoT
