S32K358 uSDHC async mode

Hi,

I am trying to use async data transfer mode of uSDHC, are there any detailed instructions? It seems the example project 'Usdhc_Ip_Example_S32K358' only shows how to use polling mode.

For example, in the code above, is it ok to simply change the last parameter to 'True' to use the async mode? However, as far as I know, there should be an interrupt to inform CPU the transfer has ended. 

So how should I configure the async mode correctly?

Best wishes

Hi,

as far as I know module interrupt are enabled by driver and in case of Async mode you should configure user callback as well in Usdhc component and this callback will be called upon that event happen.
However I am not aware of the demo for this.

BR, Petr
