[ECOS] delete from fis directory

[ECOS] delete from fis directory

[fazio]

Hi,
it is possible to delete an image from fis directory using only 
flash_program to set the image to 0xff without erasing the entire 
block with flash_erase?
Thanks

From my point of view , an Atmel-like flash  I mean,
you can't as the minimum is a sector (or a block for some others)

What is your device ?
Why doing so ? even if you could, I'm not sure that you'll gain some time or
lifecycle

Re: [ECOS] delete from fis directory

[fazio]

Thanks for your reply,
My platform is a nec v850.
I wrote a server application able to listen for a connection from a client that can send 
a file to upload on the board. After receiving the file and copying it in flash and 
changing the fconfig, it reboots the platform executing the new application that must 
delete the old. 
It can delete the flash, but when it has to delete the image from fis directory, the 
flash_program gives an error ("Driver timed out waiting for device"). 
My problem is: I would to delete the piece of fis directory containing the old apllication 
info (flash_base, lenght, checksum,...) but I'm executing another application in the 
flash. 
I cannot erase the fis dir block because I'm executing another application, so how can 
I delete only a piece of the fis dir?
Thanks

Re: [ECOS] delete from fis directory

Did I understood well :
- you need to update the new config by erasing the old.
- the old is in use

A solution could be to load the application executed in flash in RAM, just
during the update time.

Re: [ECOS] delete from fis directory

The problem is that the application is executed in RAM, but it seems that an access  
on its reference in flash generates the error "Driver timed out waiting for device". 
Thanks
