iMX25 and MT29F2G08 WinCE bootup issue

andrew_questps · ‎01-10-2013

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
