Offset and environmet size as defined in myboard.h for u-boot compilation. I suppose flash sector size is the erase (block size).

Any help please?

There is nothing special about the u-boot env. The parameters are in human readable format if you dump the contents [or used to be last time I looked]. And the fw_xxx tools just access the flash through the normal MTD layer.

With this in mind, can you access that block using the standard utilities? cat? dd? einfo? erase? etc. If not, your MTD configuration for your board is broken.
