I'm working on a digital instrument cluster ver2.0 project now.
Get freescale's instrument cluster demo project is very good,
Get some peripheral's(SPI FLASH, DMA, UART, etc) drivers and example projects is good.
And, the matter is how can I use a SPI Flash as system external memory for storing / loading image data?
( SYSTEM HAS NOT EXTERNAL DRAM)
(use CodeWarrior)
Thanks.

Hi,
MPC5645S has QuadSPI module that can be used to connect external serial flash to store images. Data in external flash are available directly in memory map because the read access automatically triggers appropriate command sequence for read. See please reference manual for more details.
I can provide simple example that shows how to erase/write/read the external QSPI flash - see attachment. It is written for MPC5606S which has QSPI module too.

Lukas
