Reference designs

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.

List of reference designs

Board	Design	Reference design name	eCos template name	RedBoot	eCos
S3E1600E	opb	Xilinx-Spartan3E1600-RevA-opb-edk92	Xilinx Spartan3e1600 opb edk92	yes	yes
S3E1600E	plb	Xilinx-Spartan3E1600-RevA-xps-edk92	Xilinx Spartan3e1600 xps edk92	yes	yes
ml505	plb	Xilinx-ml505-xps-edk92	Xilinx ml505 xps edk92	yes	in progress

for eCos configuration use ecos BSP or top BSP.

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
