Hi,
We are building a application for Serial NAND Flash(IS37SML01G01) 128MB on NXP1050 Board.
According to datasheet of NAND and Booloader reference example which we got from SDK we created the following LUT Table:-
Protocol:- FlexSPI
Port:- kFLEXSPI_PortB1
##################LUT TABLE###############################
//PAGE READ FROM MEM TO CACHE SDR 13h 3 0 0
[4 * NAND_CMD_LUT_SEQ_IDX_READ_PAGE] =
FLEXSPI_LUT_SEQ(kFLEXSPI_Command_SDR, kFLEXSPI_1PAD, SPINAND_OP_PAGE_READ,kFLEXSPI_Command_RADDR_SDR, kFLEXSPI_1PAD, 0x18), //0x18 24 bits
//PAGE READ FROM CACHE 03h, 0Bh 2 1 1 to 2112
[4 * NAND_CMD_LUT_SEQ_IDX_READ_CACHE_NORMAL] =
FLEXSPI_LUT_SEQ(kFLEXSPI_Command_SDR, kFLEXSPI_1PAD, 0x03, kFLEXSPI_Command_CADDR_SDR, kFLEXSPI_1PAD, 0x10), //0x10 16 bits (128/64/32/16/8/4/2/1)
[4 * NAND_CMD_LUT_SEQ_IDX_READ_CACHE_NORMAL + 1] =
FLEXSPI_LUT_SEQ(kFLEXSPI_Command_READ_SDR, kFLEXSPI_1PAD, 0x80, kFLEXSPI_Command_STOP, kFLEXSPI_1PAD, 0),

{

}

//flashXfer.dataSize = FLASH_PAGE_SIZE;
flashXfer.dataSize = (size_t)length;
status = FLEXSPI_TransferBlocking(base, &flashXfer);
if (status != kStatus_Success)
{
return status;
}
return status;
}
Log which i got from read:-
0x7F7F21C8 0x7F 0x7F7F21C8 0x7F 0x7F7F21C8 0x7F 0x7F7F21C8 0x7F 0x7F7F21C8 0x7F 0x7F7F21C8 0x7F 0x7F7F21C8 0x7F 0x7F7F21C8 0x7F 0x7F7F21C8 0x7F 0x7F7F21C8 0x7F 0x7F7F21C8 0x7F 0x7F7F21C8 0x7F 0x7F7F21C8 0x7F 0x7F7F21C8 0x7F 0x7F7F21C8 0x7F 0x7F7F21C8 0x7F 0x7F7F21C8 0x7F 0x7F7F21C8 0x7F 0x7F7F21C8 0x7F 0x7F7F21C8 0x7F 0x7F7F21C8 0x7F 0x7F7F21C8 0x7F 0x7F7F21C8 0x7F 0x7F7F21C8 0x7F 0x7F7F21C8 0x7F 0x7F7F21C8 0x7F 0x7F7F21C8 0x7F 0x7F7F21C8 0x7F 0x7F7F21C8 0x7F 0x7F7F21C8 0x7F 0x7F7F21C8 0x7F 0x7F7F21C8 0x7F
After Prepare page read command from flash to cache command i tried
or
memset(DataBuffer, 0xFFU, sizeof(DataBuffer));
memcpy(DataBuffer, (void *)(EXAMPLE_FLEXSPI_AMBA_BASE + 8000000), length);
or
memset(DataBuffer, 0xFFU, sizeof(DataBuffer));
memcpy(DataBuffer, (void *)(EXAMPLE_FLEXSPI_AMBA_BASE + 0), length);
If we call the above command the application stucks.
How to get the Base Address which we connected B1 Port.
Please help us to solve this issue.
