  1. Q::What is the function of the JP4 on DE2-115?
    A:The JP4 on DE2-115 is designed and reserved for MIPS cpu; users can also use it for general FPGA IO design application.
  2. Q::What OS does the USB driver of DE2-115 support
    A:DE2-115 is equipped with two types of USB chips; they are NXP ISP1362 and Cyptess cy7c67200. The DE2-115 currently available comes with Cypress cy7c67200. The driver provided in the system CD supports windows 7 for 32 /64bit and Windows XP for 32/64bit.
  3. Q::What can you do when failing to download the .sof file into the FPGA of the DE2-115 and encountering the situation as shown below??
    A:Normally the checksum and usercode should be the same (as shown below). From the previous picture, we can see the USB-Blaster hardware exists, but the checksum and the usercode are different. In this situation, please make sure your JP2 jumper setting and the JTAG-Chain are correct (for more details, please refer to DE2_115_User_manual.pdf, page No. 30)..
