I have a custom board with the l452cc controller. I am trying to run an sd card with fatfs through spi. I have generated cubemx fatfs files, but there is no interface layer for spi to fatfs. Are there some examples I can reference off of, or what is ...

Well I don't know if this gets what you are wanting to know but here is a piece of code that I ran. BYTE buf[2048]; memset(buf, 0x4c, sizeof(buf)); UINT br, bw; fr = f_write(&fil, buf, sizeof(buf), &bw);The file when I look at it is filled wi...

I haven't tried much besides a basic hello world text file. I will see here at some point. The card is formatted with FAT, and I have tried exFat too and that works. I will post back after I have tried some bigger files.

So apparently 'Check boot record signature' is what is firing the error. if (ld_word(fs->win + BS_55AA) != 0xAA55) return 3; /* Check boot record signature (always placed here even if the sector size is >512) */It would almost seem like I have a spi ...

Here is a logic capture of the above code. You will have to rename 'SD_init.sal.txt' to 'SD_init.sal', thanks to a forum quirk.
