Press KEY0 forcontinued test.The program will display progressing and result information, as shown in Figure 8-16.Figure 8-16 Display Progress and Result Information for the SDRAM Demonstration145Chapter 9Appendix9.1 Programming the Serial Configuration DeviceThis section describes how to program the serial configuration device with Serial Flash Loader(SFL) function via the JTAG interface. User can program serial configuration devices with a JTAGindirect configuration (.jic) file. To generate JIC programming files with the Quartus II software,users need to generate a user-specified SRAM object file (.sof) of the circuit they wish to put in theserial configuration device.
Next, users need to convert the SOF to a JIC file. To convert a SOF to aJIC file in Quartus II software, follow these steps:Convert SOF to JIC1.Select File > Convert Programming Files…2.In the Convert Programming Files dialog box, set the Programming file type field to JTAGIndirect Configuration File (.jic).3.In the Configuration device field, specify the targeted serial configuration device, EPCS64.4.In the File name field, browse to the target directory and specify an output file name.5.Highlight the SOF Data row in the table, as shown in Figure 9-1.6.Click Add File.7.Select the SOF that you want to convert to a JIC file.8.Click Open.1469.Highlight the Flash Loader and click Add Device, as shown in Figure 9-2.10. Click OK. The Select Devices page displays.Figure 9-1 Convert Programming Files Dialog Box147Figure 9-2 Highlight Flash Loader11.
Select the targeted FPGA, Cyclone IV E EP4CE22, as shown in Figure 9-3.12. Click OK. The Convert Programming Files page displays, should look like Figure 9-4.13. Select the .sof file, and Click the Properties. Select Compression, click OK, as shown inFigure 9-5.14. Click Generate.148Figure 9-3 Select Devices Page149Figure 9-4 Convert Programming Files Page150Figure 9-5 Compression the sof fileWrite JIC File into Serial Configuration DeviceTo program the serial configuration device with the JIC file that you just created, add the file to theQuartus II Programmer window and follow the steps:1.When the SOF-to-JIC file conversion is complete, add the JIC file to the Quartus IIProgrammer window:i.
Select Tools > Programmer. The Chain1.cdf window displays.ii. Click Add File. From the Select Programming File page, browse to the JIC file.iii. Click Open.1512.Program the serial configuration device by checking the corresponding Program/Configurebox, a Factory default SFL image will be load (See Figure 9-6).Figure 9-6 Quartus II programmer window with one JIC file3.Click Start to program serial configuration device.Erase the Serial Configuration DeviceTo erase the existed file in the serial configuration device, follow the steps listed below:1.Select Tools > Programmer. The Chain1.cdf window displays.2.Click Add File.
From the Select Programming File page, browse to a JIC file.3.Click Open.4.Erase the serial configuration device by checking the corresponding Erase box, a Factory152default SFL image will be load (See Figure 9-7).Figure 9-7 Erasing setting in Quartus II programmer window5.Click Start to erase the serial configuration device.1539.2 EPCS Programming via nios-2-flash-programmerBefore programming the EPCS via nios-2-flash-programmer, users must add an EPCS patch filenios-flash-override.txt into the Nios II EDS folder. The patch file is available in the folderDemonstation\EPCS_Patch of DE0-Nano System CD. Please copy this file to the folder[QuartusInstalledFolder]\nios2eds\bin (e.g.
C:\altera\11.1\nios2eds\bin)If the patch file is not included into the Nios II EDS folder, an error will occur as shown in Figure9-8.Figure 9-8 EPCS Message9.3 Revision Histor yVersionV1.0V1.3V1.4V1.5V1.6V1.7V1.8Change LogInitial Version (Preliminary)Add Table 3-1,3-2 and 3-3Modified Digital Accelerometer Description on page 31Modified ADC description on page 32Corrected Digital Accelerometer Schematic on page 23Modified Altera EPCS16 to be Spansion EPCS64Add SDRAM test section9.4 Copyright StatementCopyright © 2012 Terasic Technologies.
