iMX25 and MT29F2G08 WinCE bootup issue

[andrew_questps]

I am having trouble with WinCE and the MT29F2G08ABAEAWP, I can program it correctly through the ATK, but when eboot goes to jump to WinCE nothing happens. If I reset the board it then enters USB load mode (as though the flash is empty). I dumped the flash and I can see that xldr is still present but eboot has been erased.

Here is the config from NANDTypes.h I am using for the chip:

//MT29F2G08 - 10
    {
        {NAND, 2048, 2048 * 64, 64, 2048},          //FlashInfo   fi;
        {0x2C, 0xDA, 0x90, 0x95},                   //BYTE        NANDCode[NANDID_LENGTH]
        3,                                          //BYTE        NumBlockCycles
        5,                                          //BYTE        ChipAddrCycleNum
        8,                                          //BYTE        DataWidth
        1,                                          //BYTE        BBMarkNum
        {0},                                        //BYTE        BBMarkPage
        6,                                          //BYTE        StatusBusyBit
        0,                                          //BYTE        StatusErrorBit
        64,                                         //WORD        SpareDataLength
        0x70,                                       //BYTE        CmdReadStatus
        0x00,                                       //BYTE        CmdRead1
        0x30,                                       //BYTE        CmdRead2
        0x90,                                       //BYTE        CmdReadId
        0xff,                                       //BYTE        CmdReset
        0x80,                                       //BYTE        CmdWrite1
        0x10,                                       //BYTE        CmdWrite2
        0x60,                                       //BYTE        CmdErase1
        0xD0,                                       //BYTE        CmdErase2
        {12, 5, 12, 20}                             //NANDTiming  timings
    },

Has anyone got that NAND flash chip working with WinCE (6 or 7) and if so what settings are required?

I have followed the application note AN4111 with regards to how to change the NAND flash files, but it still won't work correctly. I have added the files as suggested and now have MT29F2G08.h and MT29F2G08.inc with the values above from the datasheet.

Here is the trace from eboot:

Ok, this was my bad - after adding the new header files and .inc files I forgot to add the define to the sources file for the NAND - added

!IF "$(BSP_NAND_MT29F2G08)" == "1"
CDEFINES=$(CDEFINES) -DBSP_NAND_MT29F2G08
!ENDIF

to the file PLATFORM/BSP/SRC/COMMON/NANDFMD/sources and the correct header files were included and the image works fine across reboots.

Now I think I need to change the way eboot works so that it can actually look up all the correct values, although I'm not sure how to provide a lookup table in assembler for XLDR! Might have to borrow from uboot and load all of eboot + xldr using the bootrom.

Cheers.

Hi Webster,

I am trying to boot eboot from NAND in iMX6Q.

I have posted my issue in the post: iMX6Q NAND Boot issue in WinCE

Please look at this and help me to solve this issue.

Thanks.

With regards,

Keshava
