F28335 sci with BeagleBone Black

eisenheim

hi, i want to control c2000 with beaglebone black. when i use hyperterminal receice and transmit data, it works without anyproblems(SW1 OFF, j9 populated). when i use beaglebone. c2000 doens't receive any data. i can not send anything from beaglebone (SW1 ON, j9 non-populated). so what is wrong. everything seems fine.

Hi,

Did you observe the RX waveform? Is it that the data is sent from beaglebone but C2000 doesn't receive it?

Regards,

both systems work seperately. c2000 communicates with pc and beaglebone uart1 communicates with uart2. when i connect them together i can not send any data from beaglebone. c2000 opening message appears on beaglebone terminal. so connection is correct and c2000 transmits data. but unfortunately doesn't receive anything.
