I am using MMC card inSPI mode.
I do Initialize very good and compeletly.
when I write 512 byte in card, and read data, I cant read exact data!!!
for example I write : 0 1 2 3 4 5 6 7 8 9 10
when I read buffer[5], I supposed to have 5, but I see 10!!!
It means that I have a problem with addresses, and I dont know really what to do. :cry:
pls help me. its very unusual problem.
:cry:
 

Post your code with details

Then someone will find out the error
 

hi.. i think i have the similar problem
i try to make a data logger using microcontroller, the code is already tested using micro SD Card, and the result is very good, but when i try to used MMC Card, it doesn't work..

then i found that the initialisation is little bit different, and now i already init the MMC Card - result ok, but i still could not read or write to the MMC Card,,

to your experience, what's wrong in the code? because using SD Card, it's work..
