Hi I rewrite the jz_hwcontrol to :
--
static void jz_hwcontrol(......)
{       ......
        if (ctrl & NAND_CTRL_CHANGE) {
                if (ctrl & NAND_NCE)
                        REG_EMC_NFCSR |= EMC_NFCSR_NFCE1;
                else
                        REG_EMC_NFCSR &= ~EMC_NFCSR_NFCE1;

                if (ctrl & NAND_CLE)
                ......
        }
}
and
" nand->cmd_ctrl =  jz_hwcontrol; " in board_nand_init

but it's still not work:
the error message:
--
NAND:  nand_get_flash_type: second ID read did not match ff,ff against
00,00
No NAND device found!!!

0 MiB
--

what can cause this problem?

thanks
