Motorola MCF5235EVB
|
|
===================
|
|
CPU: MCF5235, 150MHz
|
|
RAM: 16M
|
|
ROM: 2M
|
|
|
|
This is a Motorola evaluation board that uses the MCF5235 Coldfire CPU.
|
|
This board is running at 150MHz scaled from a 25MHz oscillator.
|
|
|
|
By default the BSP creates an image file for use when loaded into the
|
|
RAM of the evaluation board. To create an image file to boot from flash
|
|
add the following command to the applications Makefile:
|
|
LDFLAGS += -qnolinkcmds -T linkcmdsflash
|
|
|
|
Note: This BSP has also been tested with the Freescale / Axiom Manufacturing
|
|
(M5235BCC Business Card Controller) evaluation board.
|
|
|
