DE10-nano startup problem.

Hi all,

I use DE10-nano to develop my SoC system. I create my hardware and firmware already.

The hardware programs into FPGA and the firmware puts into SD card.

But, when I remove adapter and then plugin adapter, the system will crashed.

The system crashes when LWFPGA access peripheral register using alt_write_word or alt_read_word.

I need to push cold or warm reset button, the program can run success.

Have anyone encounters the same problem?

Could you please provide me any information to resolve the problem.
