Hai all,
I am working with 2 Evaluation boards of TMS320F28335 for Tx'ing and RX'ing data with SCIA configured for 2Mbps baud rate on both sides.
Board 1 and 2's grounds are connected.
Board 2 transmits 17-bytes of data with SCI Tx Interrupt enabled for every 2ms(code dumped in Flash) and working as expected.
Issue:
Board 1 waits for data with SCI Rx Interrupt enabled with FIFO level set to 1-byte.
As soon as Board 1 receives 1st byte Framing Error bit(FE of SCIRXST register) is set to 1.
Sometimes the Break-detect flag(BRKDT of SCIRXST register) is set and Rx interrupt of is not generated any more.
Please suggest me what reasons to consider for this problem?
Thankyou,
Lakshmi Komali.
