advice on embedded linux on an FreeScale SoC MCU MPC56xx

I wan't to port linux to a MCU EVB the mcu is freescale MPC5604P, is there some advice on how to do that? or some web site we can start on ?

Note: Cpu is an e200z0, PowerPC.

Solution

  • It is not feasible to run Linux on this device. It runs at 64MHz and has 512Kb of on-chip flash and 64kb of on-chip SRAM and no external memory interface. Linux required more like 4Mb/256Mb and will be a bit sluggish below 200MHz especially with respect to boot time.

    You would use this device with either no OS or a simple RTOS. Freescale's product page lists EB tresos AutoCore OS and EB tresos Safety OS. Boot time of a typical RTOS would ne measured in milliseconds or less.
