Hi,
I am using uboot on the MX31 PDk board. I am trying to dump the
contents of a status register found at location 50004004. This status
register shows the status of the SDHC( SD card host controller) like
interrupt , card insertion, card removal etc. According to the MX31
manual, the status register i.e the contents at the corresponding
memory location should change on events like card insertion and
removal. But the contents aren't changing as expected.
I have verified this with Linux and it works.
i) Before card insertion
=> md.l 50004004
50004004: 30004000 00000008 00000000 00000040
ii)After card insertion
=> md.l 50004004
50004004: 30004000 00000008 00000000 00000040
Could anything be wrong with my u-boot image or the memory
initialization(although anything going wrong with the init dosent
make sense).
Thanks in advance!
Thanks,
Alfred
