Let's rephrase it: the only chance you have on a MMU-less system is by using uCLinux. For standard Linux a working MMU is mandatory.
Note that it seens that uCLinux has already been ported to the ARM946.
Thanks. Now I know what I need to focus.
- Boot loader?
with MMU, such as 926. Or more general question: does u-boot support processors without MMU? From my ppc experience I know MMU is enabled on u-boot.
And you are wrong: U-Boot does NOT use the MMU on PPC. [At least not on all processors, and if then not for virtual memory but just to play dirt^H^H^H^Hclever tricks with the data cache.]
Oh. I see. Enabling MMU on PPC is just some dirt & clever tricks with the data cache. I saw the code to enable MMU in start.S. Hmmm...maybe a bit detail is more helpful to understand why MMU is enabled. Maybe I need to go back to the processor's user guide.
Does ELDK support ARM946? ELDK supports arm920. ELDK can be used for arm946 if its core is compatible with arm920's. If ELDK doesn't
You can use the cross toolchain, but the ative target tools will of course not run as they require a standard Linux kernel, not uCLinux.
?? What target tools are you talking about? I thought the target tools refer to cross compiler, debugger, etc..
