has explained in my previous question, I have found a lot of problems interfacing my BF518 based board with secure digital. I followed slavishly BF518 EZ Kit schematics and related code (Power On Self Test) Rev. 1.0.0.
This code does not work! Analyzing the same code for BF609 I have found some differences and applying the same modifications to my code now it work! But only on few SD card types. Many of these cards don't go over auto identifications process while other cards type shown problems on read write operations. My question is: exist an updated version of the Power On Self Test for BF518?
I have built a product (that I hope of large diffusion) but I have a big difficult to explain to my customer that my product can work only with few SD card types.
Thank you in advance for any help.
