How to programe different MAC addresses into each iMX28 based board through MfgTool

[x10]

Hi, all

I'm considering how to programe an unique MAC address into each iMX28 board through MfgTool. Can I get the source code of MfgTool from somewhere? My last project is based in iMX25, and I just did modification on ATK as its source code is available on freesacle web site. The unique MAC address is programmed into board through ATK. So I wander if I can get the source code of MfgTool.

Thanks for any help.

BitBurner can flash HW_OCOTP_CUST0, HW_OCOTP_CUST1 manually, which is too slow to meet our requirements. It will be fine if MfgTool can run an exe program after the current programming process done each time. Is it possible to implement?

Thanks for your suggestion so quickly. I download BitBurner_1.0.5.3, is it the latest version. I haven't used BitBurner before, so I'm not sure if it can program OTP bits automatically and sequentially. Anyway, I'll learn hwo to use it.

Thanks again.

/linux/arch/arm/mach-mx28

..

static void __init mx28_init_fec(void)

{

{
 struct platform_device *pdev;
 struct mxs_dev_lookup *lookup;
 struct fec_platform_data *pfec;
 int i;
 u32 val;

 __raw_writel(BM_OCOTP_CTRL_RD_BANK_OPEN,
   IO_ADDRESS(OCOTP_PHYS_ADDR) + HW_OCOTP_CTRL_SET);

 while (BM_OCOTP_CTRL_BUSY &
  __raw_readl(IO_ADDRESS(OCOTP_PHYS_ADDR) + HW_OCOTP_CTRL))
  udelay(10);

 lookup = mxs_get_devices("mxs-fec");
 if (lookup == NULL || IS_ERR(lookup))
  return;

 for (i = 0; i < lookup->size; i++) {
  pdev = lookup->pdev + i;
  val =  __raw_readl(IO_ADDRESS(OCOTP_PHYS_ADDR) +
      HW_OCOTP_CUSTn(pdev->id));
  switch (pdev->id) {
  case 0:
   pdev->resource = fec0_resource;
   pdev->num_resources = ARRAY_SIZE(fec0_resource);
   pdev->dev.platform_data = &fec_pdata0;
   break;
  case 1:
   pdev->resource = fec1_resource;
   pdev->num_resources = ARRAY_SIZE(fec1_resource);
   pdev->dev.platform_data = &fec_pdata1;
   break;
  default:
   return;
  }

  pfec = (struct fec_platform_data *)pdev->dev.platform_data;
  pfec->mac[0] = 0x00;
  pfec->mac[1] = 0x04;
  pfec->mac[2] = (val >> 24) & 0xFF;
  pfec->mac[3] = (val >> 16) & 0xFF;
  pfec->mac[4] = (val >> 8) & 0xFF;
  pfec->mac[5] = (val >> 0) & 0xFF;

  mxs_add_device(pdev, 2);
 }
}

so use Bitburner to flash HW_OCOTP_CUST0, HW_OCOTP_CUST1. if you don't have this tools, contact your FAE.

I also want to change the MACs, butthe device.c which is delivered with the freescale vm for ltib doesn't look like yours.

static void __init mx28_init_fec(void)

{

    struct platform_device *pdev;

    struct mxs_dev_lookup *lookup;

    int i;

    lookup = mxs_get_devices("mxs-fec");

    if (lookup == NULL || IS_ERR(lookup))

        return;

    for (i = 0; i < lookup->size; i++) {

        pdev = lookup->pdev + i;

        switch (pdev->id) {

        case 0:

            pdev->resource = fec0_resource;

            pdev->num_resources = ARRAY_SIZE(fec0_resource);

            pdev->dev.platform_data = &fec_pdata0;

            break;

        case 1:

            pdev->resource = fec1_resource;

            pdev->num_resources = ARRAY_SIZE(fec1_resource);

            pdev->dev.platform_data = &fec_pdata1;

            break;

        default:

            return;

        }

        mxs_add_device(pdev, 2);

    }

}

Patch 0087-ENGR00125760-2-MX28-read-mac-address-from-fuse.patch is the answer.
