Replacing Kernel on SAM9-L9260


Hello,

I use a board, which is based on a SAM9-L9260. There are 2 flash's on this board. On the first, the small one, is the kernel and the bootloader (u-boot).

The bootloader loads the kernel into the ram and boots it with some parameters.

The filesystem is on the second flash (the big one). Sometimes i need a software-update. And sometimes maybe the kernel should be replaced. The kernel is on e defined address in the small ram. There are the boot-parameters for the kernel too.

For the flash's i have some devices:
/dev/mtd*

/dev/mtd0 is the small flash.
Is there a way to write something to a specific address in mtd0?

regards
toredo

I am not sure if I got you right, but I think you will have to cross compile the kernel for your target system.

No problem. I have compiled it. The system is perfectly running.

But i wanna to feature to update the kernel from everywhere. I will compile the kernel localy and then i will send this on a way to the device.
