Hi, I have a problem with the TMS570LC4357 . I want to use the loopback function for the SCI. Therefore I enable the loopback function and write something in the transmit buffer register. Now when I am debugging, and have a breakpoint directly after the send function (writes the data in the transmit buffer register) it works well. But when I have the breakpoint later, the written value is in the transmit buffer register but the flag, which shows that the transmit buffer register was written, isn't changed. When I change the value from the transmit buffer register manually by debugging, it also works well. It looks like it is only a problem in the loopback mode, because without loopback transmission mode it works fine. Does anyone know what the problem is? Thanks
