| 4 | 1. Board Description |
| 5 | |
| 6 | The mvBC-P is a 70x40x40mm multi board gigabit ethernet network camera |
| 7 | with main focus on GigEVision protocol in combination with local image |
| 8 | preprocessing. |
| 9 | |
| 10 | Power Supply is either VDC 48V or Pover over Ethernet (PoE). |

| Andre Schwarz | 5e0de0e | 2008-07-09 18:30:44 +0200 | [diff] [blame] | 24 | 2.3 FPGA |
| 25 | Altera Cyclone-II EP2C8 with PCI DMA engine. |
| 26 | Connects to Matrix Vision specific CCD/CMOS sensor interface. |
| 27 | Utilizes 64MB Nand Flash. |
| 28 | |
| 29 | 2.3.1 I/O @ FPGA |
| 30 | 2 Outputs : photo coupler |
| 31 | 2 Inputs : photo coupler |
| 32 | |
| 33 | 2.4 I2C |
| 34 | LM75 @ 0x90 for temperature monitoring. |
| 35 | EEPROM @ 0xA0 for vendor specifics. |
| 36 | image sensor interface (slave adresses depend on sensor) |
| 37 | |
| 38 | 3 Flash layout. |
| 39 | |
| 40 | reset vector is 0x00000100, i.e. "LOWBOOT". |
| 41 | |
| 42 | FF800000 u-boot |
| 43 | FF840000 u-boot script image |
| 44 | FF850000 redundant u-boot script image |
| 45 | FF860000 FPGA raw bit file |
| 46 | FF8A0000 tbd. |
| 47 | FF900000 root FS |
| 48 | FFC00000 kernel |
| 49 | FFFC0000 device tree blob |
| 50 | FFFD0000 redundant device tree blob |
| 51 | FFFE0000 environment |
| 52 | FFFF0000 redundant environment |
| 53 | |
| 54 | mtd partitions are propagated to linux kernel via device tree blob. |
| 55 | |
| 56 | 4 Booting |
| 57 | |
| 58 | On startup the bootscript @ FF840000 is executed. This script can be |
| 59 | exchanged easily. Default boot mode is "boot from flash", i.e. system |
| 60 | works stand-alone. |
| 61 | |
| 62 | This behaviour depends on some environment variables : |
| 63 | |
| 64 | "netboot" : yes ->try dhcp/bootp and boot from network. |
| 65 | A "dhcp_client_id" and "dhcp_vendor-class-identifier" can be used for |
| 66 | DHCP server configuration, e.g. to provide different images to |
| 67 | different devices. |
| 68 | |
| 69 | During netboot the system tries to get 3 image files: |
| 70 | 1. Kernel - name + data is given during BOOTP. |
| 71 | 2. Initrd - name is stored in "initrd_name" |
| 72 | 3. device tree blob - name is stored in "dtb_name" |
| 73 | Fallback files are the flash versions. |
