For some reason, the board we are using only has 8MB memory(CPU is BF532). So the memory is not continues. They are allocated in memory space: 0x0~0x01FFFFF, 0x0400000~0x05FFFFF, 0x0800000~0x09FFFFF, 0x0C00000~0x0DFFFFF. So if we want to porting ucLinux to this platform. What shall we do to customize the system configuration. Is there a configuration file like "ldf" file when we develop with VisualDSP?

 

Thanks.

It is nearly impossible for you to load and run current kernel image on discrete memory region. I don't think it worths your effert to change the kernel. Change your hardware design insead.

there is no linker script for you to muck with things

 

you can attempt to follow this page:

http://docs.blackfin.uclinux.org/doku.php?id=reduce_kernel_memory_footprint

 

but really you should just do like sonic says: change the hardware design to have 16megs as that'll make software a *lot* easier
