Board Description + + The mvSMR is a 75x130mm single image processing board used + in automation. Power Supply is 24VDC. + +2 System Components + +2.1 CPU + Freescale MPC5200B CPU running at 400MHz core and 133MHz XLB/IPB. + 64MB DDR-I @ 133MHz. + 8 MByte Nor Flash on local bus. + 2 serial ports. Console running on ttyS0 @ 115200 8N1. + +2.2 PCI + PCI clock fixed at 33MHz due to old'n'slow Xilinx PCI core. + +2.3 FPGA + Xilinx Spartan-3 XC3S200 with PCI DMA engine. + Connects to Matrix Vision specific CCD/CMOS sensor interface. + +2.4 I2C + EEPROM @ 0xA0 for vendor specifics. + image sensor interface (slave adresses depend on sensor) + +3 Flash layout. + + reset vector is 0x00000100, i.e. "LOWBOOT". + + FF800000 u-boot + FF806000 u-boot script image + FF808000 u-boot environment + FF840000 FPGA raw bit file + FF880000 root FS + FFF00000 kernel + +4 Booting + + On startup the bootscript @ FF806000 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" + Fallback files are the flash versions. |
