Subject: [Emc-users] Compiling mesa bit files

Hi All,

I am trying my hand at getting my own mesa pin files compiled. I am getting 
this error :


C:\xxx\5i25\configs\hostmot2\source\hostmot2\sserialwa.vhd" Line 282: Cannot 
find  in library 


What source/project file are you using? there is no file called sslbp.vhd in the 
current source.




I dont see a VHD file in the directory but there is a zip file with some 
source in that is named sslbp. I take it that I have to compile that somehow 
but I have no idea how. Any suggestions?




No, that's not needed, its just the microcontroller code for SSLBP
Its already been assembled into a VHDL ROM image file


P.S. I am compiling the code for hm2pci project
