Hi all,

I got a question regarding protected sectors. When I build the u-boot image and program the image into the flash I can see that the area of u-boot is protected. My u-boot image needs about 3 sectors but 4 sectors are protected. Could someone please tell me in which file I can change the amount of protected sectors?

In the 4th sector very likely your environment is stored. U-Boot calculates the sectors to protect automatically (if your board is configured properly, of course). Sectors which will be protected are: U-Boot itself + Envorionment + (if configured) redundant Environment.

Please note, that this protection normally is only a software protection. If you access your flash outside from U-Boot (Debugger, OS, ...) this protection is not effective.
