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
