FreeRTOS+FAT is still in the lab
FreeRTOS+FAT is already in use in commercial products
and we encourage you to try it yourself. Be aware however that
FreeRTOS+FAT was acquired by Real Time Engineers Ltd., and is
still being documented and updated to
ensure it meets our strict quality standards.
Please use the forum for support,

A pointer to a standard null terminated C string that holds

errno may be set to indicate the reason. A task

void vExampleFunction( void )
/* Create a sub directory called subfolder. */
ff_mkdir( "subfolder" );
/* Create a in subfolder called sub1. */
ff_mkdir( "subfolder/sub1" );
/* Make subfolder/sub1 the current working directory. */
ff_chdir( "subfolder/sub1" );
/* Make the route directory the current working directory again. This could
also have used ff_chdir( "/" ); */
ff_chdir( "../.." );
