Description: Arcturus Networks uC DIMM ColdFire 5282
============
CPU: MCF5282, 64MHz
RAM: 16M
SRAM: 64k (BSP places FEC buffer descriptors here)
ROM: 4M
This is a credit-card sized board in a DIMM format. It is part of a family
which includes Dragonball and Coldfire CPUs, with a standardized DIMM-based bus.
ACKNOWLEDGEMENTS:
=================
This BSP is based on the work of:
D. Peter Siddons
Till Straumann
Brett Swimley
Jay Monkman
TODO:
=====
The bsp relies on the Arcturus monitor to set up DRAM and all chip selects.
This seems OK to me, but others may find it lame.....
I/O pin restrictions make simultaneous operation
of I2C, CAN and UART2 impossible. The BSP configures UART2 to
use the CAN pins and leaves the I2C pins available for use.
BSP NAME: uC5282
BOARD: Arcturus Netrworks uCdimm 5282
BUS: Arcturus DIMM bus, A24/D16, plus peripherals.
CPU FAMILY: ColdFire 5282
CPU: MCF5282
COPROCESSORS: N/A
DEBUG MONITOR: Arcturus bootloader

Downloading the image to the board.
===================================
The bootable image is generated by the make-exe target in the bsp makefile. It
generates a simple stripped binary file which is downloaded over the ethernet
port into RAM then executed or programmed into flash memory.
1) Power up the uC5282 board. A dump of some memory maps is produced
followed by a prompt.
2) (first time only)
Set the uC5282 board Internet configuration:
setenv IPADDR0 www.xxx.yyy.zzz (Your board's address)
setenv NETMASK ppp.qqq.rrr.sss (Your local network address mask)
setenv HOSTNAME somename (Your board's name)
3) Type 'tftp<CR>'
This forces the network link to half-duplex. If your network link is
locked at full duplex you'll have to find another port!
The RTEMS network driver can be forced to 100 Mbs/full-duplex by setting
the bootstrap environment variable IPADDR0_100FULL to Y. The driver can
be forced to 10 Mbs/half-duplex by setting the bootstrap environment
variable IPADDR0_10HALF to Y.
4) Run 'tftp' on your host machine:
tftp> binary
tftp> connect www.xxx.yyy.zzz (Your ucDIMM's address)
tftp> put someFile.exe (someFile.boot for the EPICS build system)
5) When the file has downloaded press the <ESC> key to terminate
the uCDIMM tftp command.
6) Type 'goram<CR>' to start the downloaded program, or type 'program<CR>'
to burn the code onto the uCDIMM flash.
EPICS Bootstrap Information
===========================
The EPICS startup code uses the following environment variables. If an
optional environment variable is missing the value in parentheses will be used.
All Internet addresses must be given in 'dotted-decimal' format.
HWADDR0 - Ethernet hardware address.
IPADDR0 - Internet address (192.168.0.2).
NETMASK - Local network address mask (255.255.252.0).
HOSTNAME - Internet host name (iocNobody).
GATEWAY - Internet address of gateway machine (NULL).
SERVER - Internet address of NFS server (192.168.0.1).
NAMESERVER - Internet address of DNS server (SERVER).
DOMAIN - DNS domain name (precompiled value from CONFIG_SITE).
NTPSERVER - Internet address of NTP server (SERVER).
BOOTFILE - Path to executable (epics/iocNobody/bin/RTEMS-uC5282/myApp.boot).
CMDLINE - Path to startup script (epics/iocBoot/iocNobody/st.cmd).
NFSMOUNT - NFS information: www.xxx.yyy.zzz:/remote/path /localpath
A : can also be used to separate the remote and local paths.
If NFSMOUNT is not set, SERVER will be used as the NFS server,
and the remote and local paths will be taken from the first
component of CMDLINE. If CMDLINE does not begin with a /
then '/tftpboot' is prepended to the remote path. This allows
a remote TFTP and NFS server to be handled transaparently.
