Matrix Vision mvSMR
|
|
-------------------
|
|
|
|
1. 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 addresses 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.
