Re: [Xc3sprog-users] XC2C384: it _almost_ works but doesn't quite

Hello Uwe,

it is related to two issues I reported back in the beginning of the year.
<http://sourceforge.net/mailarchive/message.php?msg_id=28809703>

One is the size of the buffer, which we had just above. The other is:

While porting the cable's implementation to another system, I noticed that
the assumption of bursts of more than 32 bits to be aligned is false as
long as the burst is not multiple of 32 (64 is ok but 63 has to be
realigned).

I assumed that it happens seldom, possibly because the application does not
use bursts on non-32-multiple numbers. But there might be an exception.
Take a look on the port where I commented it:

Some followups:

Best regards,
Raul
