0001 Motorola MCF5235EVB
0002 ===================
0003 CPU: MCF5235, 150MHz
0004 RAM: 16M
0005 ROM: 2M
0006
0007 This is a Motorola evaluation board that uses the MCF5235 Coldfire CPU.
0008 This board is running at 150MHz scaled from a 25MHz oscillator.
0009
0010 By default the BSP creates an image file for use when loaded into the
0011 RAM of the evaluation board. To create an image file to boot from flash
0012 add the following command to the applications Makefile:
0013 LDFLAGS += -qnolinkcmds -T linkcmdsflash
0014
0015 Note: This BSP has also been tested with the Freescale / Axiom Manufacturing
0016 (M5235BCC Business Card Controller) evaluation board.
