[U-Boot-Users] USB Uboot on OSK5912

[Shivdas Gujare]

Hi Jon,
This is what I observed, I needed to modify usbdcore_omap1510.c file to get
it complied properly with usbtty.c
Also, After disabling  following code from  usbdcore_omap1510.c,

  /* Set and check APLL */
     outw (0x0008, APLL_CTRL);
      UDCREG (APLL_CTRL);
      /* Set and check DPLL */
      outw (0x2210, DPLL_CTRL);
      UDCREG (DPLL_CTRL);

I was able to get Uboot console over USB on osk5912, but is not stable.

Now, I will test this with other suggested modifications.

Thanks for your Replies.

Thanks and Regards,
Shivdas Gujare
