SD card on STM32F4 issue

Post by Domantas » Mon Jan 05, 2015 11:11 am

Hi,
I have seen some bug reports related to this topic, but still no luck with my issue. I am trying to hook up a SD card to STM32F4 board. I am planning to write quite a lot of data to it, but my board does not recognise it. I followed this tutorial: http://gpio.kaltpost.de/?p=2199 but with no luck.
Maybe I am missing something simple ? I am quite new to ARMs and python in general (I have just some experience with C, ASM and 8bit processors).
Any help appreciated

Are you using an STM32F4 discovery board? If you are using code that is known to work, then most likely it is a hardware problem.

SD cards (especially cheap ones) can be very crappy!

Get one from a well known respected trademark!
