This might sound familiar. I'm working on getting FatFS and SDIO-4 bit communication working. My evaluation board is a NUCLEOF411RE. The latest problem I've run into is on line 355 of sd_diskio.c, which it gets to from ff.c, line 5661 (shown below). ...

I'm trying to communicate with a SanDisk Ultra 16GB microSD HC card (mounted with this) using a NUCLEOf411RE board, SDIO and FATFS. I've been trying to follow this post as a guideline, and I keep running into an issue in f_mkfs where it constantly re...

I was sitting down to start getting to grips with SDIO and FATFS when I realized that the only microSD breakout I have literally lacks the pins for it (missing an eighth pin for 4-bit data). I was already considering getting another NUCLEO board, but...

I'm working on a project that involves using FATFS and I was curious if I had to use the specified anti-tamp pin that gets shown. I declare other input GPIO, but only PC13 shows up as PC13-ANTI_TAMP

I've seen this around and I was hoping to get additional information on how to track down why this is the case.I'm writing a Neopixel driver for an STM32F411RE based on this example. The example works good, and I've been working on getting a struct-b...

Okay, I might have found what's wrong, but I can't say for sure. It looks like the problem is the SD card. The errors seem to start piling up once I get to line 3013 of stm32f4xx_hal_sd.c, which checks "if((scr[1U] & SDMMC_WIDE_BUS_SUPPORT) != SDMMC_...

This is what I'm seeing in the diskio.c file as I go down the layers in mkfs. Do I need to dive further down or look around in here during the fs_mount function?edit: I think I forgot to mention (and I feel real *** for this now that I think about it...

You, my friend, are a saint. Sorry I didn't respond earlier.

More or less answers my question.As to the project, it's kind of multi-step. I haven't worked with microSD or I2S before, so I wanted to start relatively simple and make an mp3 or wav player, with a MAX98357A I2S amplifier. Once I have my bearings wi...

Looks like it wasn't the problem! It was the timer suggestion you gave me that fixed most of it. I mentioned this in the updated question, but now the LEDs are responding as they should, though there is still one issue, in that those random LEDs stil...
