Hi I have try to merge Ingenic U-boot (1.1.6) with upstream. but I have some problem
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!!!

what can cause this problem?
