We are testing AN4258 on an TWR-S12G128, and we are finding troubles with RS232 reception. We have noticed that only disconnecting hyperterminal, bytes are correctly received on EVB side.
Data reception on hyperterminal side is correct, but also connecting directly TX/RX header pins or using two EVB connected between them, everything work correctly (a compare between tx/rx buffer show that).
Did anyone find same problem?
Attached files show our hyperterminal configuration, as suggested on ch 5.3 of AN4258, rev 0, 02/2011
Thank you in advance,
