Can I run Windows CE or Linux on Oki’s ARM7 MCUs?
Operating systems such as Windows CE and Linux require a Memory Management Unit (MMU) to run. ARM7TDMI cores do not have a built in MMU. Therefore Windows CE is not supported on them. There are versions of Embedded Linux that can run on micros without an MMU. One such popular version of Linux is uCLinux. For more information on this refer to www.lineo.com In the ARM world, generally ARM cores that have the name ARMX2XTxxx, the 2 designates MMU capability and thus support for operating systems such as Linux and Windows CE. For example ARM920T or ARM720T have MMUs.
