AM5746: regarding control during boot using SD card.

?? ?
Prodigy 40 points
Part Number: AM5746

I have a question regarding control at startup using an SD card.

In software that uses hard macros, we measured the waveform of the part related to the SD card.
As a result, there is a part where the waveform of "CLK" is not a pulse wave.

I would like to know if this is a normal waveform.
The schematic is the same configuration as "AM574X_INDUSTRIAL_EVM_SCH_1_0A.pdf" with no pull-up resistor and damper resistor is 0Ω.

best regards.

    Greetings,

    It seems like the there may be a speed change in between Scene 1 and Scene 2, and either the probe, the scope, or both were not able to capture the higher data toggle rate properly.  Please increase the resolution to capture the signals properly.
