The MCU Cog has an on-board debugger which supports the ARM CMSIS DAP interface. When connecting up the EV-COG-AD4050LZ to your computer or laptop, all the necessary drivers are automatically located and loaded up when using Windows operating systems.
There are two sets of drivers that get installed on your computer depending on which mode of operation the EV-COG-AD4050LZ emulator comes up.
It EXTREMELY important to ensure that all drivers are installed, before trying to use the EV-COG-AD4050LZ with the CrossCore Embedded Tools. So when you see that the drivers are being installed in the task bar, open it up and wait till everything finished before progressing.
When the EV-COG-AD4050LZ emulator is connected to the ADuCM4050 and ready for program/debug mode, the “DAPLINK” drive is displayed on your computer.
This mode allows users to drag and drop (or copy and paste) a .BIN or .HEX [Intel formatted] file directly into the DAPLINK drive, and that file will be flashed directly to the ADuCM4050. This means you don't have to use the tools or the debugger to program your board, making this very useful in production releases or updating applications already in the field.
When the EV-COG-AD4050LZ emulator is connected to the MK20DX128VFM5 (by holding down the “RST” button while connecting the USB port (P5) to the PC/laptop) the “Maintenance” drive is displayed on your computer. This mode allows a user to overwrite the ADuCM4050 interface file within the emulator. This allows for patches and updates to the firmware on the emulator.
