STM32F429zi ram drive code

[ECrom.1]

Hi all,

Where can I find code example for STM32F429zi ram drive code

I see FatFS and other examples, but no ram-drive FatFS example

I need to open a device over USB to be recognized by the PC HOST

Thanks

I swear I posted an answer here.

I had written and posted an STM32F429I-DISCO SDRAMDISK back in the SPL days

For HAL/Cube you will probably need to find a MSC HOST for the EVAL boards, port to the DISCO, add SDRAM initialization, and change the IO to copy in/out of SDRAM

Following me prev. question:

I am using STM32F429zi board

But found a RAM_DISK example for 9i board

I ran with / without RTOS

In both cases :

all these word fine (return woth OK :(

FATFS_LinkDriver, f_mount, f_mkfs,

But when I call f_open I get FR_NO_FILESYSTEM

How can that be ?
