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.
