2.5 External SPI Flash
The board provides optional onboard external SPI flash up to 4MB for bootable
devices using DOS Operating System. If required, please contact with Advantech’s
sales rep to support onboard external SPI flash by request, and follows below steps
to enable external SPI flash.
1. If you want to use the external SPI flash as storage for read/ write in DOS OS,
please adjust the BIOS SETUP \Advanced Chipset Features\Virtual Disk to
“Enabled”. and then use “SPITOOL.exe” on the Drive CD to format it, so that
you can read/write external SPI flash.
2. If you want to utilize the external SPI flash as a bootable device in DOS OS,
please make a DOS bootable disk on a CF card or IDE hard drive, boot from the
DOS bootable disk and then perform format A: /s pointing towards the external
flash.Next, set the BIOS SETUP\ Boot Device to “FLOPPY”, so that you can
boot from the external SPI DOS OS.
2.6 SPI Connector (CN1)
The board provides 6-pin external SPI connector for external SPI device and periph-
eral usage.
2.7 VGA/LVDS/TTL interface connections
The PCM-3343’s VGA interface can drive conventional CRT displays and is capable
of driving LVDS and TTL flat panel displays. The board has three connectors to sup-
port these displays: one for standard CRT VGA monitors, one for LVDS type LCD
panels, another one for LVDS type LCD panels.
PCM-3343 uses SMI SM712 2D graphic Chip offering enhanced capabilities for dual
view and for handling dual applications, CRT+TTL, and CRT +LVDS. Each display
can support independent full screen full motion video, as well as independent graph-
ics refresh rates, resolutions, and color depths.
LVDS and TTL can support resolutions of 640 x 480,800 x 480,800 x 600, and 1024 x
768.
