Do the MCXA153 drivers support I3C HDR-DDR mode?

ASM — Mon, 03 Mar 2025 18:58:39 GMT

Hi,

In the example code I have, I can see that there is at least some code to support DDR, but it doesn't seem to work. Is it fully implemented, and if so, is there an example of how to use it?

Thanks

Hi @ASM,

As mentioned on the following community post: Solved: Re: Does RT685 support I3C HDR-DDR mode? - NXP Community

HDR-DDR mode has issues on both the RT and MCX A devices, so please use SDR instead.
