STM32F4 eMMC support

Posted on May 12, 2018 at 13:47

Hello there,

I am writing in regard to those 2 topics:

https://community.st.com/thread/49792-sm32l4-interface-with-an-emmc

I am using an STM32L452 chip and trying to fully utilize the SanDisk 8GB eMMC memory (

SDINBDG4-8G

). I have found out that the is no eMMC HAL written for the L4 family. Because of that, I tried STM32F412, as it uses SDIO not SDMMC peripheral (the same thing but other name?), and it has HAL written. I have found out however, that as pointed out here

it doesnt work. There are no examples of eMMC usage in STM32Cube_FW_F4_V1.0. From the code it also seems that it only supports memories up to 2 GB. Trying to use the code I was unable to write anything to the momory, like the mentioned topic, even though over a year passed since it was posted.

At the moment I have a serious design dilemma. I cannot afford the time to write the driver from scratch or try to fix the existing one. Could I please ask for an explanation what is the state of the eMMC driver for each STM32F4 and STM32L4 devices, do they indeed not work? Is there a way to make them work? Also, what is the real difference between SDIO which F4 utilize and SDMMC peripherals which L4 utilize? I would appreciate all help.

Hi,

The project was proof of concept 4 years back and now i seem to have lost the project still i'll look into my archive if i find it i'll share here

Can you give me a quote for a demo of emmc working on a STM32F401RET6 please?

Hi Clive, I can't get you on Private Message, I am looking for a Demo of eMMC memory on a STM32F401RET6 (or closest family member)
