Hello,

 

I'm trying to use I2S module from  MK22FN512 in FRDM-K22F board, with the KSDK + Processor expert.

I used the fsl_sai component as shown in the figure below:

Basically I used the bean's default settings. However, the program is stuck in a line code generated by the PE.

The line of code are highlighted in the figure below.

As can be seen in the next figure extracted from the device's manual, it is a register indicating whether the device clock may or

not be updated.

The code appears to have been poorly designed, should not get stuck in this condition. What can I do? Programming using registers?

Freescale does not seem to give much support for I2S module.

 

Thanks,
