Micron Active Serial Configuration Arria 10

In our design we use a NOR Flash memory from Micron (MT25QU01GBBB8E12-0SIT) as configuration device and the FPGA Arria 10 (10AX027E4F29E3SG). We write to the Flash via the FPGA using a .jic file. T...

    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.

The 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.
