eCos BSP

New ecos BSP was developed for improving configuration. The BSP is located in hw/edk_repository. The BSP helps you generate eCos configuration for your design. Together with mon_new_platfrom script, it brings up a powerful tool for adding new platforms to mONeCos distribution. If you experience any problems with the ecos BSP, please, report them to Michal Simek.

• run EDK
  • Windows: Start → Programs → Xilinx EDK → Xilinx Platform Studio
  • Linux: source your Xilinx tools (ISE and EDK) and run xps

[monstr@monstr ~]$ cd /opt/xilinx/ise92i/
[monstr@monstr ise92i]$ . settings.sh
[monstr@monstr ise92i]$ cd ../edk92i/
[monstr@monstr edk92i]$ . settings.sh
[monstr@monstr edk92i]$ xps

• open your design and configure software setting Software → Software Platform Settings
  • choose OS & Library setting to latest ecos BSP
  • set the correct value of CORE_CLOCK_FREQ_HZ
    • this value is used for eCos timing setting
  • the following figure shows setting the BSP

• choose a proper name for your design – this name will be used in mONeCos
  • avoid using “/” character!

* here is a corresponding block that was added in system.mss file

PARAMETER VERSION = 2.2.0

BEGIN OS
 PARAMETER OS_NAME = ecos
 PARAMETER OS_VER = 1.00.a
 PARAMETER PROC_INSTANCE = microblaze_0
 PARAMETER name = Spartan 3E1600
END

• build your library
  • Software → Generate Libraries and BSPs
  • or alternatively from a shell you can call

make -f system.make libs

• here is the interesting part of log, you can see calling eCos BSP

[monstr@monstr Xilinx-Spartan3E1600-RevA-edk92-opb-gpio]$ make -f system.make libs

• if the configuration ends without any error you can continue to next step
• please report any problems to Michal Simek

To save your time, you can also use top BSP, which generates all BSPs for your eCos, Linux, U-Boot, http://developer.petalogix.com/PetaLinux and standalone applications. Reference design Xilinx-Spartan3E1600-RevA-xps-edk92 shows this feature. (PetaLinux BSP is not distributed with mONeCos)

BEGIN OS
 PARAMETER OS_NAME = top
 PARAMETER OS_VER = 1.00.b
 PARAMETER PROC_INSTANCE = microblaze_0
 PARAMETER name = Xilinx Spartan3e1600 xps edk92
 PARAMETER timer = xps_timer_1
 PARAMETER ethernet = Ethernet_MAC
 PARAMETER gpio = LEDs_6Bit
 PARAMETER lmb_memory = dlmb_cntlr
 PARAMETER flash_memory = FLASH
 PARAMETER main_memory = DDR_SDRAM
 PARAMETER stdin = RS232_DTE
 PARAMETER stdout = RS232_DTE
