Subject: RE: [ECOS] Error when changing 'fconfig' redboot values from a linux program

Thierry,
In my case RedBoot config is on mtd5 partition (do cat /proc/mtd to see) and I open the device:
Open("/dev/mtd5", O_RDWR | O_SYNC). With the handle returned by the open function I do read and write operations as for any other device.
