Making FAT delete work

[Camilo Alejandro Arboleda]

Hi,

I'm updating my application from RTEMS 4.5 to RTEMS 4.6.2. After some 
work I made my flash driver work in the new version. But now I find that 
'unlink()' doesn't work anymore.

As far as I can see, the problem is in the msdos_eval_path() function. 
Before deleting the file, RTEMS try to check permissions for ".." 
directory, but msdos_eval_path fails with 'ENOTDIR'. I want to copy the 
IMFS functionality, but I'm not able to figure how to open the parent 
node of a file on msdosfs.

Maybe I'm missing something. Is there someone who is using FAT support 
and is able to delete files?


Thanks in advance,

Camilo Alejandro Arboleda
