FatFs F4 SDIO broken on latest CubeMX

The latest version of CubeMX (4.21) with F4 Libs (v1.16) using the SDIO controller seems to have broken FatFS support.  ff.c needs a file that declares the character sets being used because it contains a couple of utility routines.  This may only be needed for long file names but regardless it is missing.  I fixed it by copying the ccsbcs.c file from the repository (under Middlewares/Third_Party/FatFs/src/options) and it resolves the issue.  This was not a problem in earlier versions.

Also, is the system ever going to support wide bus operation with DMA without the user having to manually configure this?

Hi

Bauch.Aaron

,

Could you please confirm if this behavior is faced when you load an old project or when create a new project?

Please attachyour ioc file for further check.

I just tested the new F2 HAL library v1.6.0 (created a fresh project) and when manually setting SDIO to DMA by changing the function calls in SD_read/SD_write to their _DMA counterparts, it won't work at all anymore. It's no problem with v1.4.0.

So I'll stick with 1.4.0 for this proejct.

I'm exactly in the same case, 1.16 sdio dma driver is broken and polling method is not stable, many txunderrun error occurs, even if I disable interrupt during fifo writing. Please fix it.

Reliance on third-parties to provide robust code is a dangerous position to put one's self in.

There is a strong case for ST to start dog-fooding their own code, and using it in real apps, with real consequences. At the moment 'barely working' is a sufficient threshold for example/demo code, there needs to be significantly more ownership and responsibility for delivering better code. How some of this stuff gets beyond a simple code review or LINT/MISRA compliance baffles me.

Hi

Bauch.Aaron

,

A doc (

https://community.st.com/0D50X00009bMM7JSAW

) was created to help people to configureCubeMX + SDIO + DMA +FatSF.

The example is applicable on devices with two DMA channels for SDIO (F2/F4/F7).

I hope it will help you.
