Honored Contributor
Honored Contributorthe 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

14.01.2005 12:04:34 - (info) nios2-flash-programmer: flash programming completeafter 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 --- Quote End --- In our case the generated script defined a wrong EPCS device type (EPCS16 i.s.o. EPCS4). | V 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 .
