HOW TO GET WEIM 32BIT DATA IN MX51

[arunkmrvn]

hi eveyone,

I am using i.mx51 processor connected to FPGA through EMI bus. I want to read and write 32bit data from the FPGA. But Whenever i am going to read, i am getting only 16bit word. Right now i am using multiplexed asynchronous mode  to get 32bit word data. The Registers for configuration is all changed to 32bit. Please see the below confgurations and suggest me anyone, how to get 32bit data from EMI bus.

#define CSGCR1    0x00

#define CSGCR2    0x04

#define CSRCR1    0x08

#define CSRCR2    0x0C

#define CSWCR1    0x10

#define WEIM_CS5_OFFSET 0X78

__raw_writel(0x00F33089, (u32)weim_vbaddr + WEIM_CS5_OFFSET + CSGCR1);

__raw_writel(0x00000002, (u32)weim_vbaddr + WEIM_CS5_OFFSET + CSGCR2);

__raw_writel(0x32260000, (u32)weim_vbaddr + WEIM_CS5_OFFSET + CSRCR1);

__raw_writel(0, (u32)weim_vbaddr + WEIM_CS5_OFFSET + CSRCR2);

__raw_writel(0x72080F00, (u32)weim_vbaddr + WEIM_CS5_OFFSET + CSWCR1);

Read function in driver
static int mxc_emi_read(struct file *file, int *buf,size_t count, loff_t *f_pos)

{

    printk("Emi chipselect5 Read called\n");

    u32 temp;

    u32 address = buf[0];

    temp  =  readl(cs5addr+address);

    printk(KERN_INFO "Data read inside kernel %x\n",temp);

    return temp;

}

What changes have to made to read the 32bit data from FPGA ?

Hello,

  Please check pin configuration for Multiplexed Address/Data Mode, using
Table 52 (WEIM Interface Pinout in Various Configurations) of the i.MX51
Datasheet.

http://cache.nxp.com/files/dsp/doc/data_sheet/IMX51CEC.pdf?pspll=1 

  Please pay attention on influence of the AUS bit in Chip Select 5 General Configuration

Register 1 (CS5GCR1) - looks like it is set in Your case.

Have a great day,
Yuri

I mean, is there any possibility to get 32bit data in EIM DA[0-16] and EIM D[16-31] only. I used some of NAND_F pins as GPIO. So, is there any possibility.

[Yuri]

Hello,

all possible configurations are shown in Table 52 (WEIM Interface Pinout in

Various Configurations) of the i.MX51  Datasheet.

hi yuri,

Its worked after mapped NAND_F lines to hardware. Thanks for your

support

Thanks & Regards,

Hi Yuri Muhin,

I am using in

FPGA lines are mapped to EIM-DA(0-15), EIMD(16-31), EIMA(16-27) and LBA, OE, WE signals.

Address -> EIMDA(0-15) + EIMA(16-27)

Data -> EIMDA(0-15) + EIMD(16-31)

I am using asynchronous communication in multiplexed mode (MUM=1), EIMDA0-DA15 pins (Address & Data ) to get first 16bit Data and EIMD16-D31 (Data) Next 16 bit Data and AUS bit is set. (AUS=1).

This is my pin configuration file

Hello,

from the table 52 of the Datasheet :

A[15:0] - EIM_DA[15:0]

A[27:16] -  NANDF_D[11:0]

D[7:0] - EIM_DA[7:0]

D[15:8] - EIM_DA[15:8]

D[23:16] - NANDF_D[7:0]

D[31:24] - NANDF_D[15:8]

Regards,

Yuri.

Hi Yuri,

I followed what you told and as per table 52. I am trying to get 8 bit non-muxed data. using below configuration.

   __raw_writel(0x00463081, (u32)weim_vbaddr + WEIM_CS5_OFFSET + CSGCR1);

   __raw_writel(0x00000000, (u32)weim_vbaddr + WEIM_CS5_OFFSET + CSGCR2);

        __raw_writel(0x32260000, (u32)weim_vbaddr + WEIM_CS5_OFFSET + CSRCR1);

    __raw_writel(0, (u32)weim_vbaddr + WEIM_CS5_OFFSET + CSRCR2);

MUM =0, AUS=0, DSZ=110.

Add - > EIMDA[0-27]

Data -> EIMD[23-16]

But still i am getting 16 bit data.

I Stored 0x12345678 in FPGA.

I tried to access 8 bit. but still i am getting 0x1234 as a result.[dsz=110]

I tried to access 16 bit. but still i am getting 0x1234 as a result. [dsz=010, mum=0]

I tried to access 16 bit. but still i am getting 0x1234 as a result. [dsz=001, mum=1]

i thought, code is not compiled properly, so given debug message & printed raw data of configuration [GCR,RCR] also. Its changing fine, but still i am unable to find out error. what's happening ?

what's the possibility way to clear this error ?

please give your mail id. i'll send the source files.
