CubeMx 4.12.0 Mcu: STM32L476RETx Fimware Package: L4V1.2.0

-Cube is generating code for port H, but there's no port H on the L476RET

/*Configure GPIO pins : PH0 PH1 */

GPIO_InitStruct.Pin = GPIO_PIN_0 | GPIO_PIN_1;

GPIO_InitStruct.Mode = GPIO_MODE_ANALOG;

GPIO_InitStruct.Pull = GPIO_NOPULL;

HAL_GPIO_Init(GPIOH, &GPIO_InitStruct);

-In sd_diskio.c

const Diskio_drvTypeDef SD_Driver =

Should be without the const

Hi Edje,

1-Cube is generating code for port H, but there's no port H on the L476RET

Please refer to the product datasheet, in fact the port H exist (PH0-OSC_IN (PH0) â€“ PH1/OSC_OUT)

2-Const Diskio_drvTypeDef SD_Driver = Should be without the const

Could you please let us know what kind of problem did you faced with this declaration that leads to this conclusion?

Hi Syrine,

Thanks for your quick reply.

1. That's really stupid of me, missed those 2 pins. Need some fresh coffee.

2. fmount() will return a FR_INVALIDE_DRIVE, because the path argument is not valid.

And that's is because Disknum in FATFS_LinkDriverEx is 0xbd instead of 0x00.

In your example c:\Users\e\STM32Cube\Repository\STM32Cube_FW_L4_V1.2.0\Projects\STM32L476G_EVAL\Demonstrations\MB1144\Core\Src\k_sd_diskio.c it was without the const and that made it work for me.

Hi Edje,

You said that the demonstration project works fine for you, try to add const to the structure declaration and the demo will still work properly (I tested it). So, I donâ€™t think that this declaration is the root cause of your problem.

Can you please share your project with us? Forum users may bring you some help.

Hi Syrine,

Thanks for your reply.

I didn't say that the example project was working, I ''said'' that there are differences comparing the code generate by CubeMx and the example project. The difference found made my project work.

Attached my test project including the ioc file.

In regard to the ''const'' problem mentioned above and using Cube 4.13.0:

Error[Pe1061]: declaration of variable ''SD_Driver'' is incompatible with a declaration in another translation unit C:\Software\In House Projects\Lab Card Reader\Middlewares\Third_Party\FatFs\src\drivers\sd_diskio.h 36
