# # $Id$ # Description: Arcturus Networks uC DIMM ColdFire 5282 ============ CPU: MCF5282, 64MHz RAM: 16M 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 Brett Swimley Jay Monkman TODO: ===== Make a clean exit routine to return to Arcturus monitor 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..... 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 PERIPHERALS =========== TIMERS: Four PIT (RTEMS clock is PIT3), Four Timers RESOLUTION: 1 microsecond SERIAL PORTS: Internal UART 1, 2 and 3 REAL-TIME CLOCK: none DMA: none VIDEO: none SCSI: none NETWORKING: Internal 10/100MHz FEC DRIVER INFORMATION ================== CLOCK DRIVER: PIT3 IOSUPP DRIVER: none SHMSUPP: none TIMER DRIVER: TIMER3 TTY DRIVER: UART1, 2 and 3 STDIO ===== PORT: UART1 Terminal ELECTRICAL: RS-232 BAUD: 9600 BITS PER CHARACTER: 8 PARITY: None STOP BITS: 1 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 map is produced followed by a prompt. 2) type 'tftp' 3) Run 'tftp' on your host machine: tftp> binary tftp> connect www.xxx.yyy.zzz (You're ucDIMM's address) tftp> put someFile.exe 4) When the file has downloaded press the key to terminate the uCDIMM tftp command. 5) Type 'goram' to start the downloaded program, or type 'program' 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). LOGSERVER - Internet address of syslog server (SERVER). BOOTFILE - Path to executable (epics/iocNobody/bin/RTEMS-uC5282/myApp.boot). CMDLINE - Path to startup script (epics/iocBoot/iocNobody/st.cmd). ============================================================================ Memory map as set up by dBUG bootstrap and BSP
