IMX RT1060 CMD line conflict in uSDHC

[ZohaibAli]

Hi,

I am enabling the uSDHC-1 with a driver and I am getting CTOE and CCE bits set in the Interrupt Status Register of uSDHC-1. I studied the reference manual and it tells me this is CMD line conflict. Please tell me what are the possible reasons for this CMD line conflict and how can I resolve it. I am using a micro-SDHC UHS-1 compatible card in the TF-Card slot.

Hi,

Are you testing this in the EVK? Are you using SDK example code or you created your own application?

I have seen sometimes this issue is caused by wrong initialization in the uSDHC pins, so please double check pin muxing and initialization.

Best regards,

Felipe
