Hi, i was testing the Modules LINFLEX_0, LINFLEX_1, LINFLEX_2, LINFLEX_3, LINFLEX_M0 and LINFLEX_M1 configuring either that a module (Ej.: LINFLEX_M1) drive the transmision Tx and reception Rx with DMA (enabling DMATXE and DMARXE) or that a module drive Tx and other Rx.
I test for example that LINFLEX_M1 drive Rx while LINFLEX_0 drive Tx and works fine. But in another cases, when i program that LINFLEX_0 drive Tx and Rx, it doesn´t send bytes.
the processor has limitations about what can drive each Module?
Hi,
so you are not able to make UART TX/RX running with DMA on LINFlex_0?
I am not aware of any issue with this. Did you set PBridges properly?
Are you able to share your config?
You can refer to https://community.nxp.com/t5/MPC5xxx-Knowledge-Base/Example-MPC5775K-UART-with-DMA-S32DS-1-0/ta-p/11... it is for different MCU but should be similar in principle.
