Valentina,
NOR flash is pin muxed with CF as far as I know on DaVinci. If you
file system is located on NOR and you need to access NOR and CF from Linux then
you need to modify the drivers to be mutually exclusive of each others
in-flight and outstanding access.

Subject: saving data to CF card when booting from flash
Hi,
Has anyone experienced this situation: boot from flash and recording some data
to CF card?
I'm using DaVinci 6446 customized board. I boot the device from NOR flash. When
I avoid communication with CF card (no data streaming to CF), the application
works perfectly fine. But, when I set 17th bit of PINMUX0 (ATAEN - to enable
CF), strange things start to happen. I set this register in the application,
because if I do it before start of the application, NOR flash wouldn't work
anymore. I know about this limitation. But, even if I set ATAEN in the
application I got alignment trap and bus error. When I run the same application
on NFS this doesn't happen.
Anyone had similar problem? Any hint is wellcome.
Thanks,
Valentina
