I am using the ST-Link utility, v4.0.0. I created a custom external loader in IAR for ARM using one of the example projects. After I build the loader in IAR I copy the .out file to ST Link's external loader folder and give it an STLDR extension. However when I go to load the file through ST Link, the Device name is blank, the Device Type is "Unknown Device, the Start address is 0 and the Device Size is 0. I know that this information comes from the Dev_Inf file but since I just modified an existing project, I think this is all setup correctly. I have built this both in IAR v7.3 and v7.8. Any guidance would be appreciated.
