Hi

i’m trying to use FreeRTOS + TCP multi on Zynq platform but when i try to compile the
source code i get some multiple definition error on some functions.
The conflict involves emacps funtions presents in …\portable\NetworkInterface\Zynq and in my BSP emacps driver funtions generated by Xilinx SDK program (version 2018.2) .
For example: setup_isr(), is_tx_space_available(), etc.
I cannot remove the sources from my Xilinx BSP because they are automatically generated based on Zynq peripheral configuration.
How can i solve the broblem?
Thanks for help

Solved by removing IwIP library from Xilinx BSP project.
