- Matrix Vision mvBlueCOUGAR-P (mvBC-P)
- -------------------------------------
- 1. Board Description
- The mvBC-P is a 70x40x40mm multi board gigabit ethernet network camera
- with main focus on GigEVision protocol in combination with local image
- preprocessing.
- Power Supply is either VDC 48V or Pover over Ethernet (PoE).
- 2 System Components
- 2.1 CPU
- Freescale MPC5200B CPU running at 400MHz core and 133MHz XLB/IPB.
- 64MB SDRAM @ 133MHz.
- 8 MByte Nor Flash on local bus.
- 1 serial ports. Console running on ttyS0 @ 115200 8N1.
- 2.2 PCI
- PCI clock fixed at 66MHz. Arbitration inside FPGA.
- Intel GD82541ER network MAC/PHY and FPGA connected.
- 2.3 FPGA
- Altera Cyclone-II EP2C8 with PCI DMA engine.
- Connects to Matrix Vision specific CCD/CMOS sensor interface.
- Utilizes 64MB Nand Flash.
- 2.3.1 I/O @ FPGA
- 2 Outputs : photo coupler
- 2 Inputs : photo coupler
- 2.4 I2C
- LM75 @ 0x90 for temperature monitoring.
- EEPROM @ 0xA0 for vendor specifics.
- image sensor interface (slave addresses depend on sensor)
- 3 Flash layout.
- reset vector is 0x00000100, i.e. "LOWBOOT".
- FF800000 u-boot
- FF840000 u-boot script image
- FF850000 redundant u-boot script image
- FF860000 FPGA raw bit file
- FF8A0000 tbd.
- FF900000 root FS
- FFC00000 kernel
- FFFC0000 device tree blob
- FFFD0000 redundant device tree blob
- FFFE0000 environment
- FFFF0000 redundant environment
- mtd partitions are propagated to linux kernel via device tree blob.
- 4 Booting
- On startup the bootscript @ FF840000 is executed. This script can be
- exchanged easily. Default boot mode is "boot from flash", i.e. system
- works stand-alone.
- This behaviour depends on some environment variables :
- "netboot" : yes ->try dhcp/bootp and boot from network.
- A "dhcp_client_id" and "dhcp_vendor-class-identifier" can be used for
- DHCP server configuration, e.g. to provide different images to
- different devices.
- During netboot the system tries to get 3 image files:
- 1. Kernel - name + data is given during BOOTP.
- 2. Initrd - name is stored in "initrd_name"
- 3. device tree blob - name is stored in "dtb_name"
- Fallback files are the flash versions.
