hi:
I am implementing TC377&S32K311 master-slave communication, 311 using FRTOS and EB MCAL as the development environment.
In the SPI initialization, the size f buffer binding by Spi_SetupEB function is the same as TC377. After I call Spi_AsyncTransmit function, I get an underrurn error. Observing the logic analyzer, the date is unnormal as shown in Figure 1 and Figure2.
During SPI initialization, if the size of buffer is larger than TC377, the data transmitted is normal, as shown in Figure 3, but the transmission cannot be terminated.
