Flash-Programmer problem after update to NIOS 1.1

After updating my design from Quartus 4.1 / NiosII 1.01 to Quartus 4.2 / NiosII 1.1, I couldn't programm it to EPCS completely. This worked fine under my previous installation. 

The appropriate main parts of my design are a EPCS4, cyclone EP1C12, and 1MB external SRAM (avalon-tristate-slave) and no additional Flash because the final firmware is loaded via a PCI-Bus and a separate Avalon-Master (actually disabled). My cpu has set its Restart-Address to EPCS-controller and Exception-Address to SRAM, software compiling is done with setting all three sections to SRAM. The result is verified in objdump file (All firmware is linked to the address specified in SOPC-Builder). 

My FPGA-design is named 'ComMan.pof' with EPCS4 assigned to U4, my custom board is 'CM_Board', my firmware (a own PCI-Bootloader) is located in .../CM_Boot/Debug. 

Starting flash-programmer from NIOS-IDE produces the following output: 

cd D:/Projects/CMNios/Firmware/CM_Boot/Debug # Creating .flash file for the FPGA configuration $QUARTUS_ROOTDIR/NIOS_11/bin/sof2flash --flash=U4 --offset=0x00000000 --epcs --i nput=D:/Projects/CMNios/FPGA/ACT/ComMan.sof --output=ComMan.flash Info: ******************************************************************* Info: Running Quartus II Convert_programming_file Info: Command: quartus_cpf --no_banner --convert --device=EPCS16 --option=ComMan .opt D:/Projects/CMNios/FPGA/ACT/ComMan.sof ComMan.pof Info: Quartus II Convert_programming_file was successful. 0 errors, 0 warnings    Info: Processing ended: Fri Jan 14 12:03:37 2005    Info: Elapsed time: 00:00:01 Info: ******************************************************************* Info: Running Quartus II Convert_programming_file Info: Command: quartus_cpf --no_banner --convert ComMan.pof ComMan.rpd Info: Quartus II Convert_programming_file was successful. 0 errors, 0 warnings    Info: Processing ended: Fri Jan 14 12:03:38 2005    Info: Elapsed time: 00:00:01 # Programming flash with the FPGA configuration $QUARTUS_ROOTDIR/NIOS_11/bin/nios2-flash-programmer --input=ComMan.flash --sof=D :/Projects/CMNios/FPGA/ACT/CM_Board/system/CM_Board.sof --epcs 14.01.2005 12:03:39 - (INFO) nios2-flash-programmer: Launching Quartus Programme r to download:     D:/Projects/CMNios/FPGA/ACT/CM_Board/system/CM_Board.sof Pre-Reading 148KBytes of data from U4:    |----.----+----.----|    ********************* (14.438 sec).

Verified 64Kbytes written to U4. 14.01.2005 12:04:34 - (INFO) nios2-flash-programmer: Flash programming complete  

After power Off/On I see that EPCS4 is accessed for about 65msec. With Signal-Tap I've checked that the fpga has now its new configuration loaded and reset_n is released when clock is stable (PLL locked the first time). But there is not any access (CS) to my SRAM as I expected to copy firmware from EPCS to SRAM. 

 

Has anybody an explanation? 

Thanks in advance 

Mike

In our case the generated script defined a wrong EPCS device type (EPCS16 i.s.o. EPCS4).  

 

quartus_cpf --no_banner --convert --device=EPCS16 --option=ComMan 

.opt D:/Projects/CMNios/FPGA/ACT/ComMan.sof ComMan.pof 

 

We fixed it by modifying the script .

Hi kwokwong, 

 

I've seen this also. But it seems not to be a problem. It runs after applying the patch even EPCS16 is selected. 

 

Thanks

Re: Flash-Programmer problem after update to NIOS 1.1

Have you patched the script to refer to EPCS4. (you do have EPCS4 on your board?) 

 

We have to replace sof2flash command by two quartus_cpf comands!

Hi kwokwong, 

 

Yes, I have a EPCS4 on board. This message '--device=EPCS16' is generated from the call to 'sof2flash' and is a default parameter I think. As long as my design fits in a EPCS4 I will ignore this message. Until now I see no necessity to patch the script.
