Struggling to write on a SD card with the STM32F769I_DISCO
Hello everyone,
I have to work on an already existing project using the STM32F769I_DISCO which works properly. My task is to write logs in a file on a SD card. I followed the excellent tutorial by Nicolas Fillon for STMicroelectronics about the matter, using SDMMC.
First of all, the SDMMC1 is Disabled and cannot be enabled, which is why I can only consider SDMMC2. I'm following all steps from the tutorials, I can build the project without errors, but when I try to run it on the STM, no file has been created and more importantly, I have a huge UI dysfunction :
working normally, before modifications
after enabling SDMMC2.
I reinstalled the project multiple times. Every time I try to enable SD MMC2, I have this bug, even when I don't add any line of code after generating the code. I don't have any errors on the build. After building the project at each step of the tutorial, I realized it happens when I enable SD MMC2 and I change the clocks (because I have an error if I let them by default), so even before enabling and configuring FATFS. The visual bug remains even after disabling SD MMC2.
I can't manage to find any solutions about it anywhere. Has this bug ever occurred to someone and did you manage to fix it ?
I thank you in advance for your time and your consideration. It's my first time working with an electronic board and even using C, so I surely lack knowledge and vocabulary about the matter.
