Dear all,
I am porting Nand flash driver in iMX6X WinCE 7.0 platform. I am using micron's MT29F4G16ABBDAHC nand. nand is not detecting in wince 7.0. once the wince OS is launched i am getting "No NAND type matched" print in the hyper terminal.
i added the following entries for supporting the "MT29F4G16ABBDAHC" nand in the NANDTYPES.h file:
{
{NAND, 4096, 2048 * 64, 64, 2048}, //spare area bytes are not considered
{0x2C, 0xBC, 0x90, 0x55}, //BYTE NANDCode[NANDID_LENGTH]
3, //BYTE NumBlockCycles
5, //BYTE ChipAddrCycleNum
16, //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
{25, 16, 25, 20} //NANDTiming timings
}
The driver is returning the nand id as 0. I configured the GPMICLK to 198MHz, AHB clock to 132MHz.
Please help me to solve this issue.
Regards,
Sowmya
