- Subject: [ECOS] File system over serial flash device
Hi,
I have a platform that is using serial flash device.
The device driver is already working in RedBoot/eCos.
The device driver supports:
- un/lock (sector base address)
- erase (sector base address)
- program (base address, size_to_program)
Now I'm required to add File system support in my eCos application.
As you know when programing a flash device, it is required to format
the relevant sectors before and then write to it.
My questions are:
Does the file system handle the sector erasing ?
How does the FS handle single byte programing for flash device? How
does it save the rest of file from being lost in the sector format?
Thanks
Elad
