- Subject: [ECOS] Again Big endian ARM HAL_WRITE_UINT8 problem
Hi,
there is still the problem, that the HAL_WRITE_UINT8() macro
on bigendian ARM hardware does not work.
In the following message is a solution suggested, which would
be good IMO.
http://sources.redhat.com/ml/ecos-discuss/2002-07/msg00415.html
I don't know which platform have to use the macros for bigendian
like they are, maybe pid target? I uses the macro and can be set
to bigendian.
I would like to make a patch, but if I use a flag like
HAL_IO_MACROS_ADDRESS_MUNGING a platform who needs the macros as
they are have to define the flag not to be broken.
Or should I define a flag like HAL_IO_MACROS_NO_ADDRESS_MUNGING
for platforms like snds which don't need the address munging?
