STM32L432KC communication with microSD card Reader via SPI

meetudiii · ‎2022-08-04

I am following this video: https://www.youtube.com/watch?v=aqSNz26Cuio&t=35s

Hardware:

STM32 Nucleo-32 for STM32L432
Adafruit microSDcard adapter: https://www.adafruit.com/product/4682
Samsung 32GB EVO (red) microSD card

Software:

STM32CubeIDE

The board used in the video is different but all the settings are also present in my STM32L432 board.

My .ioc pinout view looks like this:

Note: In video, the SPI1_SCK has been automatically given to PA5, but for my board it was shown as PA1, hence have made the connections accordingly.

FatFS enabled:

MAX_SS - 4096
USE_LFN - Enabled with static working buffer

SPI1 enabled:

Mode - Full Duplex - Master
Parameter Settings -
System Core SYS set to Serial Wire (as shown in video)

After following the video, My build is complete with no errors. Then I make the hardware connections for my board like this:

(Please excuse the microSD card not inserted in the slot)

When I am running the file to download the code to board, I am changing the run config file as shown in the video: changing the debug probe to OpenOCD (I don't know much about what this does) and changing the Reset mode to Software System Reset.

So when I click on Run, I get the following error:

When I run using the default setting in Run Config; which is debug probe set to ST-LINK (ST-LINK GDB server), I get no errors while downloading to board, but I don't see any file written on to the SD card. Attaching the console log of the same below:

I am fairly new to the whole STM32 environment.

I just want to make this STM32L432 + SPI + microSDcard thing working.

Any help is appreciated. Thank you.

SD Cards would want 512-byte sectors.

I don't use CubeMX/IDE to code.

There should be mostly working code for SPI + FATFS here

STM32Cube_FW_L4_V1.14.0\Drivers\BSP\Adafruit_Shield\stm32_adafruit_sd.c

There were some bugs with the multi-sector support that I've addressed previously on the forum, but good luck finding them, search here is an abomination..

Tips, Buy me a coffee, or three.. PayPal Venmo
Up vote any posts that you find helpful, it shows what's working..
