AM2632: Abnormal CMD0 command

feiyun su

Part Number: AM2632

Tool/software:

The APP did not send CMD0, but it was seen in the waveform of the logic analyzer as CMD0. This caused an anomaly in the SDIO device. Will the SDK automatically send CMD0? If so, where is it done?

Hello,

At what point in the code do you see this occur? This seems like an unintended command being sent by the driver which needs to be removed. Could you share the code and the line where you see this occur?

Thanks,

Sahana

Hi,
At present, it is impossible to pinpoint the exact location of the code. Two instances of "CMD0" were found in some commands.

Closing this ticket since it was told that the issue was resolved in the debug call.
