LPC2000 flash downloader baud rate

Started by topandurangs April 22, 2006
Hi all,

I am using LPC2000 flash download utility ver2.2.3.In the
utility user selectable baud rates are given.When i set baud <= 38400
my flash downloading happens properly.When i have set baud rate above
38400,utility given communication error.
Is this problem with my target board or anything else.
How should i communicate above 38400 baud rate.
Thanks in advance.
Regards,

If you look at the ISP baudrate vs crystal frequence table in the user
manual under the "set baud rate" command description, you will see
that with 12.288MHz crystal, maximum baud rate is 38400 which is what
you observed.
