    Hi,

    May I know what is the booting method, is it using SD card or QSPI etc?

    Can you elaborate on how exactly the CPU reset is called?

    Hi,

    boot from QSPI flash.

    right now customer are debugging software, reset is called in their main function.

    they called this function for CPU reset.

    ALT_STATUS_CODE alt_reset_cold_reset(void)

    {

    alt_write_word(ALT_RSTMGR_CTL_ADDR, ALT_RSTMGR_CTL_SWCOLDRSTREQ_SET_MSK);

    return ALT_E_SUCCESS;

    }
