Reference designs

In mONeCos distribution you can find some reference designs. These designs are placed in hw/design folder. In pre-built folder, there are placed bitstream, RedBoot and eCos with a test application.

  • for eCos configuration use ecos BSP or top BSP.
  • read design rules below
  • continue with the manual here

Design rules

  • use only supported peripherals for working with mONeCos
    • for different IPs is necessary to change BSP - for this please contact me
  • run ecos BSP before you start building bitstream
  • Microblaze limitation
    • use MSR instruction
    • use Barrel shifter
  • locate BRAM memory from zero address
  • check correctness of CORE_CLOCK_FREQ_HZ
  • current eCos BSP checks if your system contains minimally one uart16550 because only this driver is fully supported in eCos kernel
    • if you don't have uart16550 and you have one uartlite BSP shows warning about and you may have some problems with compilation
    • look at reference design - you can see that every system contains uart16550 and uartlite
    • if uartlite is in your system and it is enabled in configtool, RedBoot sends output to both serial interface but you can only work with uartlite
