Hi Jaehoon,
Thanks for that hint!
I uploaded two logs to pastebin.
Log [1] is a sandisk ultra 32gb sd card. This time I didn't got it work properly.
Log [2] is from an other 2gb sd card where I pressed the reset button until I received data from CMD 17 command.
Right now there are a lot of debug outputs, to make it for me easy for me to find the errors. The most of them will be removed later.
Best Regards,
Philipp Rossak

Hey everyone,
I'm currently working on a SD / MMC Card driver for the stm32f746g-disco Board. You can find my actual very early work right here on my github repository: [0]
Currently I'm getting errors that are not reproducible:
Errors on sending different commands (happens somtimes but randomly)
Errors at CMD 17 & 18 reading procedures
If you can also share the log, it's helpful to check your problem. I don't have board to test yours, but i can check your driver as code level.

And sometimes works everything without any problems....
Right now I think that my hardware got broken (but I'm not sure). It would be nice if someone could test the driver and send me the log. A small code review would help me also.
Thanks in advance!
Best regards,
