Hi,
We ordered two DEVKIT-MPC5748G boards. After failure of S32 Design Studio while trying to debug some code, I unplugged board from USB. After this I tried to debug once more and got the message about reset escalation (and also red reset LED was on). After reading your forums I saw it is bricked and there is no way to unbrick it back. Nonetheless we tried CAN communication using the other board and we succeed to transmit some messages from NXP board to PC, but in the opposite direction doesn't work. We tried it using your flexcan_dma_receive and flexcan_receive functions. Below the message you can see how we checked if CAN frame was received (with turning LED on and using debugger breakpoint). CAN is connected to PC via PEAK Gmbh 4-channel PCIe CAN FD card. Can you please provide some working receiver functions?
