[asterisk-users] bristuff for hfc card on Xscale 80219

[Stelios Koroneos]

Is your system compiled as BE or LE ?
bristuff will compile but will not work on BE systems without some
patches/endianess fixes as some of the buffer pointers are little endian
Also with the existing bristuff you will get invalid data due to the fact
that the cache controller of xscale can not snoop into the DMA transfer
cycles and update the cache
To avoid this you need to allocate a non cachable memory region for buffer.
In sort. Although it compiles it does not work :/
