Hi, I have a simple task of sending a byte to a remote device and waiting for a one byte answer.
So, for receiving data i use (code simplified to the bare minimum)
The rx line of my UART is totally disconnected so I should not receive anything but get timeouts.
uint8_t dummyByte;
lpuart_status_t status;
status = LPUART_DRV_ReceiveDataBlocking(FSL_LPUARTCOM1,&dummyByte, 1, 20);
// Now status shows timeout as expected on a disconnected UART
status = LPUART_DRV_AbortReceivingData(FSL_LPUARTCOM1);
// status is now 0 (success) as expected
status = LPUART_DRV_ReceiveDataBlocking(FSL_LPUARTCOM1,&dummyByte, 1, 20);
// Status is now 0 - successful again, why???
By the way, transmitting data works just fine.
For this code I would expect both receives to fail with a timeout.
If I omit the
status = LPUART_DRV_AbortReceivingData(FSL_LPUARTCOM1);
call then all subsequent invocations of the receive function return a BUSY status.
Any hints or solutions/
TIA, Roland
