Hy,

I'm trying to run the attached exampleSciDMA on TMDX570LC43HDK on loopback configuration but I've nothing in RX_Rata at the end of debug,

can you please check if the project ok? No settings on HalCoGen seems to be necessary.

Regards

    Hello Antonio,

    The code in main() looks good. The problem is caused by the pinmux.

    On TMS570LC43x, the SCI3_TX pin is pin W3 muxed with NHET1[6], and the SCI3TX is pin N2 which is muxed with NHET1[13]. The default function for pin W3 and N2 are NHET1[16] and NHET1[13].

    To enable SCI3 and SCI4 function, please check "SCI3" and "SCI4" under "PINMUX" in HALCoGen.

    Hy, I implemented your proposal but it is not working neither in SCI3 loopback configuration that in external connection between SCI3TX (J11 pin 49) to SCI4RX (J11 pin 53)
