Is anyone out there using STM32FCube w/ fatfs with LFN (long file names) ? My project works, but I can only get a small file name to work. I have tried all of the settings in FFCONF.h and added ccsbcs.c file.

However this was tried on an STM32F469 Discovery and worked fine. Does anyone have an STM32F405 running with an SD using a fatfs?

Thanks for your help, it all works. The trick was getting the clock just right and it all started to work. It's different than the CAN in the old STR911.

Thanks for your response. My project is an upgrade from an STR911 to the STM32. The spec defines the clock as 250 KHz. How do set the clock to get that freq. The STR911 was straight forward.

Thanks clive1, I missed that.

Thanks for your help. I had a few changes to make and finally got a successful compile. Still having some issues. What changes to ffconf.h need to be made for long file names and multiple directories?

Ok, what is the latest version and where can I get it?

Anyone using an STM32F4xx with CAN interface. I need to use this in a Receive interrupt mode. I see data on the RX input, but no interrupts.

Using the Fatfs supplied in CUBE, how can a file be deleted, specifically in a directory?

I am working with the FATFS r14 using long file names. and most all is working OK. I am more than occasionally seeing FR_NOT_READY responses on f_opendir, etc. Any ideas??

FATFS using long file names

Write issue with STM32F405 w/ SDIO using fatfs as part of CubeIDE. uSD card mounts OK, system links OK, but anytime a write operation occurs there is a fault. The hardware has been instrumented OK and checked withe same result on another PCB.
