5	Description: Arcturus Networks uC DIMM ColdFire 5282
6	============
7	CPU: MCF5282, 64MHz
8	RAM: 16M
9	ROM: 4M
10
11	This is a credit-card sized board in a DIMM format. It is part of a family
12	which includes Dragonball and Coldfire CPUs, with a standardized DIMM-based bus.
13
14	ACKNOWLEDGEMENTS:
15	=================
16	This BSP is based on the work of:
17	D. Peter Siddons
18	Brett Swimley
19	Jay Monkman
20
21	TODO:
22	=====
23	Make a clean exit routine to return to Arcturus monitor
24
25	The bsp relies on the Arcturus monitor to set up DRAM and all chip selects.
26	This seems OK to me, but others may find it lame.....

29	BSP NAME: uC5282
30	BOARD: Arcturus Netrworks uCdimm 5282
31	BUS: Arcturus DIMM bus, A24/D16, plus peripherals.
32	CPU FAMILY: ColdFire 5282
33	CPU: MCF5282
34	COPROCESSORS: N/A
35
36	DEBUG MONITOR: Arcturus bootloader
37
38	PERIPHERALS
39	===========
40	TIMERS: Four PIT (RTEMS clock is PIT3), Four Timers
41	RESOLUTION: 1 microsecond
42	SERIAL PORTS: Internal UART 1, 2 and 3
43	REAL-TIME CLOCK: none
44	DMA: none
45	VIDEO: none
46	SCSI: none
47	NETWORKING: Internal 10/100Mbs FEC, locked at 100 Mbs, full-duplex
48
49	DRIVER INFORMATION
50	==================
51	CLOCK DRIVER: PIT3
52	IOSUPP DRIVER: none
53	SHMSUPP: none
54	TIMER DRIVER: TIMER3
55	TTY DRIVER: UART1, 2 and 3
56
57	STDIO
58	=====
59	PORT: UART1 Terminal
60	ELECTRICAL: RS-232
61	BAUD: 9600
62	BITS PER CHARACTER: 8
63	PARITY: None
64	STOP BITS: 1
65
66	Downloading the image to the board.
67	===================================
68
69	The bootable image is generated by the make-exe target in the bsp makefile. It
70	generates a simple stripped binary file which is downloaded over the ethernet
71	port into RAM then executed or programmed into flash memory.
72
73	1) Power up the uC5282 board. A dump of some memory map is produced
74	followed by a prompt.
75
76	2) type 'tftp<CR>'
77
78	3) Run 'tftp' on your host machine:
79	tftp> binary
80	tftp> connect www.xxx.yyy.zzz (You're ucDIMM's address)
81	tftp> put someFile.exe
82
83	4) When the file has downloaded press the <ESC> key to terminate
84	the uCDIMM tftp command.
85
86	5) Type 'goram<CR>' to start the downloaded program, or type 'program<CR>'
87	to burn the code onto the uCDIMM flash.
88
89	EPICS Bootstrap Information
90	===========================
91	The EPICS startup code uses the following environment variables. If an
92	optional environment variable is missing the value in parentheses will be used.
93	All Internet addresses must be given in 'dotted-decimal' format.
94	HWADDR0 - Ethernet hardware address.
95	IPADDR0 - Internet address (192.168.0.2).
96	NETMASK - Local network address mask (255.255.252.0).
97	HOSTNAME - Internet host name (iocNobody).
98	GATEWAY - Internet address of gateway machine (NULL).
99	SERVER - Internet address of NFS server (192.168.0.1).
100	NAMESERVER - Internet address of DNS server (SERVER).
101	DOMAIN - DNS domain name (precompiled value from CONFIG_SITE).
102	NTPSERVER - Internet address of NTP server (SERVER).
103	LOGSERVER - Internet address of syslog server (SERVER).
104	BOOTFILE - Path to executable (epics/iocNobody/bin/RTEMS-uC5282/myApp.boot).
105	CMDLINE - Path to startup script (epics/iocBoot/iocNobody/st.cmd).
