Subject: [ECOS] FLASH access from user program
I would like to do functions similar to "fis delete" and "fis create"
from an eCos user program.
How can I get access to the FLASH?
Are there system calls for this, or do I have to move a lot of RedBoot
code into my program?
Or are there other possibilities?
All input is welcome.

Hi, and thank you for the link.
This is almost what I am looking for. There is also an virtual vector
called CYGNUM_CALL_IF_FLASH_FIS_OP which seems to be the right one.
It takes a little time to figure out the parameters, but I will try it.

AFAIK you can oly read FIS this way. If you want to modify flash
contents you have to use the flash API (<cyg/io/flash.h>).
