I have been working on SD Cards and tested the code on different brands of SD card.
All work fine but Kingston. I have tested SanDisk, ADATA and Kingston.

Whenever I use Kingston, it initializes on alternate turns i.e. if it is successfully initialized on the first attempt, it will definitely fail on the next reset and works fine on the next reset again and so on.

If the card is plug out and re-inserted before every reset, it initializes on every turn.

What could be the issue?

Tried running the initialization process again, if it fails on the first attempt. Doesn't change anything.

Tried Turning off the SD Power ,wait and Turning back on SD Power in the beginning of SD Initialization. Still same result.

Need help??

when it fails, it is because ACMD41 command timed out.
