21 years agothanks,
It was not a problem with the flash programmer, programming of the EPCS1 works with the NiosII Flash programmer (only by shell script, not from the IDE) and with the quartus programmer by using a JTAG Indirect Configuration File. There seems to be some timing problem in the startup of my software and the timing of other components on the custom board. (the HW configuration from the EPCS device is faster than the HW configuration with the configuration epld). I inserted a simple usleep(500000) in my software and now the software behaviar is the same as if I load the hw image from the configuration epld. for the problem with the debugger, I made a new debug hardware configuration, and now debugging also works. (I still wonder about the fact, that debugging worked, when I loaded the HW image from the configuration EPLD ?)
