Occasional ContributorMicron Active Serial Configuration Arria 10
Hello, the bug hasn't occured since.
I noticed that it only happened when my colleague accesses the FPGA with the debugger. Somehow something must have gone wrong with the Flash-IP in our Design and the Quartus Debugging tools.
Now the FPGA works as planned and configures itself without problems.
Regular ContributorFrom your description, it seems like the hardware connection between JTAG to FPGA and also FPGA to flash memory has no issue as you were able to program both JIC and SOF into it.
It seems like the issue is more on the memory, can you try to swap the memory with a known good memory?
LFrinThe strange thing is; If you reprogram the memory after the error occurred, configuring from the flash memory at boot up works again. We have rewritten the flash memory of our three prototypes and are currently waiting for one of them not being configured at startup.
We are still working on the firmware and we are using many debugging features via JTAG and SignalTap. Is there any possibility to write to the flash memory by mistake?
Unfortunately we do not have the possibility to swap the memory here. We would have to have our circuit board maker do it.
