Matrix Vision mvBlueLYNX-M7 (mvBL-M7) ------------------------------------- 1. Board Description The mvBL-M7 is a 120x120mm single board computing platform with strong focus on stereo image processing applications. Power Supply is either VDC 12-48V or Pover over Ethernet (PoE) on any port (requires add-on board). 2 System Components 2.1 CPU Freescale MPC8343VRAGDB CPU running at 400MHz core and 266MHz csb. 512MByte DDR-II memory @ 133MHz. 8 MByte Nor Flash on local bus. 2 Vitesse VSC8601 RGMII ethernet Phys. 1 USB host controller over ULPI I/F. 2 serial ports. Console running on ttyS0 @ 115200 8N1. 1 SD-Card slot connected to SPI. System configuration (HRCW) is taken from I2C EEPROM. 2.2 PCI A miniPCI Type-III socket is present. PCI clock fixed at 66MHz. 2.3 FPGA Altera Cyclone-II EP2C20/35 with PCI DMA engines. Connects to dual Matrix Vision specific CCD/CMOS sensor interfaces. Utilizes another 256MB DDR-II memory and 32-128MB Nand Flash. 2.3.1 I/O @ FPGA 2x8 Outputs : Infineon High-Side Switches to Main Supply. 2x8 Inputs : Programmable input threshold + trigger capabilities 2 dedicated flash interfaces for illuminator boards. Cross trigger for chaining several boards. 2.4 I2C Bus1: MAX5381 DAC @ 0x60 for 1st digital input threshold. LM75 @ 0x90 for temperature monitoring. EEPROM @ 0xA0 for system setup (HRCW etc.) + vendor specifics. 1st image sensor interface (slave addresses depend on sensor) Bus2: MAX5381 DAC @ 0x60 for 2nd digital input threshold. 2nd image sensor interface (slave addresses depend on sensor) 3 Flash layout. reset vector is 0xFFF00100, i.e. "HIGHBOOT". FF800000 environment FF802000 redundant environment FF804000 u-boot script image FF806000 redundant u-boot script image FF808000 device tree blob FF80A000 redundant device tree blob FF80C000 tbd. FF80E000 tbd. FF810000 kernel FFC00000 root FS FFF00000 u-boot FFF80000 FPGA raw bit file mtd partitions are propagated to linux kernel via device tree blob. 4 Booting On startup the bootscript @ FF804000 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.
