Hi,

I trying to build some project by implement the PMOD MTDS using microblaze on Arty A7-35T. I had followed the instructions in the README.txt of PMOD MTDS and the microblaze ip core with the PMOD MTDS ip core is successfully built with bitstream file successfully generated. However, when built the project using VITIS 2020.1, it failed. It show that "undefined reference to mydisp". When I open up the folder, it seem liked the "stdint.h" library file is not recognized by the compiler. Kindly need help on this kind of problem. 

Thanks.
