SW4STM32 and SW4Linux fully supports the STM32MP1 asymmetric multicore Cortex/A7+M4 MPUs

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world. And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4.
You can get more information from the ac6-tools website and download (registration required) various documents highlighting:

FATFS f_unlink not works, error code FR_LOCKED

Hello,

On STM32H7 development board I implemented a FatFs file system from Cube library to external qspi flash. I have a standalone system, without any RTOS.
I can read and write files, but I cant delete them. f_unlink always was resulted by a FR_LOCKED error code.
Files are closed, so it is not a problem.

I try to set _FS_LOCK parameter in ffconf.h to 0. It helps, but for better safety a would like to let it switched on. Now _FS_LOCK = 2, but in this case I cant delete files.
