As per Nick's last suggestion I dropped the baud rate to 1200 - still no joy I added some diag_printf to the serial driver ISR to catch any status bits that might be set -they are not.
When I run serial3 it successfully receives 16 and 128 bytes. When 256 bytes are requested I am geting a timeout. There must be a reason for this!!! Please can anyone suggest something else Graham -- View this message in context: http://www.nabble.com/Re%3A-Serial-communications-tp24354870p24377163.html Sent from the Sourceware - ecos-discuss mailing list archive at Nabble.com. -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
