<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I am having a problem using an ethernut 2.0 rev A when
communicating with a high speed serial device. The rate I am attempting
to communicate on is 500000 baud and it appears that data is being overrun/lost
during the transmission. The ethernut has been modified with a 16 Mhz
crystal to allow for communication on the higher then standard baud rate. I
am using uart0 and the data is “packetized” into chunks of about up
to 1.2kb and is streaming continuously.</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'> </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>My main question is can the ethernut communicate on this
rate successfully? As the data being transmitted is checked using CRC even the
loss of a single byte is bad news and will result in the loss of a complete
data packet. I have tested this application using lower baud rates and
have had no problems. If the ethernut can handle 500000 then I will focus
on optimising and tuning my application but if not then I might have to find
another solution. Also in the future I may be looking at trying to
interface with a 1500000 baud device.</span></font></p>
