I have a board based on this development board, In the project I have mqx, board and hardware init file specific to my hardware.
I use several I/O and 2 SPI that work fine. (it seems)
I want to implement an UART but without success. I tried the different solutions from the examples but no way.
I have a specific task just for the UART, in init I call
UART_DRV_Init(UART2, &uartState, &uartConfig);
I tried to add install RxCallback, etc..
I miss something ?
P.S: The BSP debug UART1 init code is commented.
I am sorry for the delay.
Do you use the board FRDM-K22F or your own board based on the FRDM-K22F?
For uart test, I suggest you output the char and hook a scope to the UART2_TX to check if there is signal.
If you do not have signal, pls check the pin assignment.
