Re: imx21-hcd bugs, device descriptor read/64, error -110

Hi,
   I have gone through the function. It reads the root hub A register
and masks it with a hex for AMD. So the masking should not apply to
i.MX 21.
   When I read the register on my own, it reads as 0. Then I tried to
print the address of the root hub A register by
&ohci->regs->roothub.a. This prints an address which is different than
the address in the ref manual of i.MX. So I might be reading from the
wrong address.
  How do I make sure that the address is correct?

Thanks,
Midhun.
