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 adresses depend on sensor) + Bus2: + MAX5381 DAC @ 0x60 for 2nd digital input threshold. + 2nd image sensor interface (slave adresses 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. + |
