Hi to all, i'm a newbie of programming embedded, i have a Stm nucleo L152RE and i a sd card shiled v 4.1 of seeed studio this is the

http://www.seeedstudio.com/wiki/SD_Card_shield_V4.0

of shiled.

Now i want use cubemx for use this shield, i use this setting:

57 PB5 GPIO_Output

I select FatFs to read and write on SDcard

now i generete the code i don't see the file sd_diskio.c, can you give me example or how to, for setting and use it.

best regards

Antonio

Hi Antonio,

Have a look at example under

STM32Cube_FW_L1_V1.2.0\Projects\STM32L152D_EVAL\Applications\FatFs\FatFs_uSD

What Antonio said is that cubeMX don't generate all the necessary files. This bug has been discovered several times :

- [DEAD LINK /public/STe2ecommunities/mcu/Lists/STM32Java/Flat.aspx?RootFolder=/public/STe2ecommunities/mcu/Lists/STM32Java/Is%20stm32cubemx%20v4.8%20a%20beta&FolderCTID=0x01200200770978C69A1141439FE559EB459D758000F9A0E3A95BA69146A17C2E80209ADC21&currentviews=106]bug 1

- [DEAD LINK /public/STe2ecommunities/mcu/Lists/STM32Java/Flat.aspx?RootFolder=/public/STe2ecommunities/mcu/Lists/STM32Java/cubemx%20v4.8%20-%20fatfs&FolderCTID=0x01200200770978C69A1141439FE559EB459D758000F9A0E3A95BA69146A17C2E80209ADC21&TopicsView=https://my.st.com/public/STe2ecommunities/mcu/Lists/STM32Java/AllItems.aspx&currentviews=40]bug 2

I can reproduce it with v4.8, STM32F4, new project from scratch. In other words,

- We are not able to update our existing projects with cubemx

- We are not able to create new projects with cubemx

- People that are not familiar with STM32 will switch to other equivalent processors

- People that are familiar with STM32 will certainly switch to other equivalent processors in a few months, after they loosed a lot of money, is ST don't fix the bug.

- Expressed as a simple manner for ST (in case they don't understand), *ST will loose money* (and there are already in a very poor economical state here in France).

Workaround for any people that don't want to wait: SD cards / fatfs works fine without effort on SAM processors.

Hi Antonio,

Without knowing more about the configuration, quite hard to reproduce (in fact, not reproduced yet, works fine for me with Mx 4.8, IAR, Win OS7: files always generated).

Would it be possible to know:

- CubeMx version in use: 4.x (with x = ?) ; standalone executable installed or Eclipse plugin used?

- OS : Linux / Windows 7, 8 or 10 ?

- toolchain being used : IAR / Keil / Atollic / SW4STM32 / ... ?

Getting your project file (the one with .ioc extension) could help as well (unless it contains confidential data)

Something I have already said in a recent FreeRTOS discussion: we need to know tools and OS versions you use for a better support.

Regards,

Fred

hi to all, thanks for your help

CubeMx version in use: 4.8.0; standalone

O.S. windows 7 64 bit

toolchain being used : Keil

i am a newbie in embedded world and i am studying for understand to use it.

can you see a easy example for learn it?

best regards

A.

p.s. in Attachments you can see my ioc file.

Hello Antonio,

The file you are looking for is under : Middlewares\Third_Party\FatFs\src\drivers.

Depending on your choice of project settings to copy or to reference the library files, this directory may be copied under your project at project generation or only kept as reference to your cube repository (see in C:/users/<your username>/STM32Cube/Repository).

Best regards.
