I am using Intel's Xscale PXA270 processor, Redboot as
my bootloader.
The iobase address is 0x10000000.
I wrote a small for loop for reading 16MB data from
0x10000000, so that it would cover the signature
register of smsc91c111.
For the entire 16MB it read 3 for even address and 0
for odd address.
In the datasheet of smsc91c111, it is mentioned that
address is 16-bit and data is 32-bit. I didnt get the
meaning of it.
Thanks with kind Regards,
