There are a bunch of devboards with the processor, but can you still get them? Probably the at91sam9g45m10ek or atmel_sama5d3_xplained are a better fit. The MIPS creator CI20 is also nice. But that's not ARM, of course. > What i think as something is already existing in buildroot & linux kernel for > support of these two boards, so its good for freshers to learn all these process > on these boards. > > Means 32 bit controller whose specs are clearly define so that one can try hand > on creating/configuring memory drivers for sdram or Nand , creating device > drivers , configuring uboot & architecture specific files, porting linux & > rfsystem & uboot made by yourself ? These things are _not_ something I would advise for an absolute beginner. Experienced consultants like me plan two to four weeks of full-time work for porting everything from a devboard to a custom board. So starting from scratch is definitely an ambitious goal. Start out with just building and installing the boot loader, kernel and rootfs for which support already exists. Then maybe you can bump the U-Boot and kernel version (and contribute patches, of course). Anyway, any devboard you can get probably already has U-Boot and kernel support, otherwise they wouldn't be able to sell it. So unless you're developing a custom board, re-implementing those from scratch is just duplicate work.
