Good morning, I'm using ARM STM32F407VGT6 to drive a 5 "LCD with the FT800 driver. I use the FAT32 library to upload images to a micro-sd. Up to now I have always used 4GB micro-sd in class 10, everything has always worked perfectly. Lately I bought some 8GB micro-sd in class 4 with the result that the images are not loaded / displayed correctly. I tried to vary the SPI speed from SPI_FPCLK_DIV8 to SPI_FPCLK_DIV16, but I did not get any results. I tried to load different versions of the FAT32 library, 108_fat32_library_V188.8.131.52 and 108_fat32_library_V184.108.40.206 but without improvements. Do you have any suggestions to give?
Good morning, I created the pachage file with the file __Lib_FAT32_STM32_M3_M4_M7.emcl. I recompiled my program and loaded it on the processor. Unfortunately the problem is still present and presents itself without any difference compared to the version compiled with the FAT32 library previously loaded.
Good morning, no news about it? For our company this is a big problem, as we have purchased a number of micro-sd cards and we have some board in production that need to be delivered, it would be important that the resolution of the problem was approached with the utmost seriousness and timeliness.
