[U-Boot-Users] minimal bootloader for arm11
Hi everyone;
I want to port linux 2.6 on an new board based on ARM1176. I am not able to find suitable bootloader for that.I have used our own bootloader to port same linux kernel on ARM9 board.
Considering the fact that I have no experince in bootloader coding. and limited knowledge of uboot code .i would appreciate if any one can help me in in following issues.
a) Can I use Uboot for our new ARM11 board. If yes. How much expertise is required.
b) If I decide to modify ower own bootloader code ; can you help me to indentify what areas required fresh coding or chagnes in reference to our board ; i want just minimal bootloader.
Thanks in advance.

Yes, you can.
You need an excellent knowledge of your architecture and your hardware; you need a thouroughunderstanding of the required initialization procedure on your hardware (CPU, timers, interrupts, I/O, devices, ...), and standard low-level programming techniques (C, assembler, linker scripts).
Summary: expert level.
b) If I decide to modify ower own bootloader code ; can you help me to indentify what areas required fresh coding or chagnes in reference to our board ; i want just minimal bootloader.
No, we cannot. This is the U-Boot mailing list, and we're discussion U-Boot only.
Best regards,

Thanks for your reply.
I would appreciate if you can guide me to identify suitable starting point for changing Uboot for my current plateform (for example files or memory mapping related).
thanks again.
