Hello, I use Connect ME -S version, NET+OS 6.0 (with LSK patch installed). I have found (and also verified with my application) that for this module there is this layout of flash memory: (c: etos60\_gnu\connect\linkerScripts\image.ld) - Connect ME Flash layout (assuming 64K sectors): - ``` 0 - 1 : Boot (reserved) ``` - ``` 2 - 3 : Post (reserved) ``` - ``` 4 - 19: EOS ``` - ``` 20- 22: "NVRAM" (3 reserved, only one used) ``` - ``` 23- 30: "FS" ``` - ``` 31 : "BootParm" (reserved) ``` I would like to use all possible flash memory for my application. I do not use flash file system, so the sectors “23-30” is useless for me. Is there some way how to change this flash memory layout and enlarge the application space? I mean move NVRAM to sector one before “BootParm” ? I have studied some possibility - customize.ldr file in platform directory, BSP\_NVRAM\_DRIVER define (“… must be set to BSP\_NVRAM\_CUSTOM”), BIOS communication area structure (bcomm) - but I have not found some efficient way how to do. Does anybody know? Thank you, Michal Dvorak
