TMS320F28377D Problem with SCI Tx

Other Parts Discussed in Thread: TMS320F28335, TMS320F28377D

Hello,

I am currently migrating from a working code from TMS320F28335 to TMS320F28377D and I have a problem with SCI.

I make a code sending periodically a character "0x5A" to my computer.

The received characters in my computer are erratic. Sometimes I receive the expected character "0x5A", sometimes I receive "0xDA".

Below a measure of the Tx GPIO with an oscilloscope

The frame is almost right, except for the last bit, duration of this bit is not stable.
