My present (short) experience of developing RTEMS applications -is essentially positive and suggestive of a long-term commitment. In -any case I am ready to answer questions regarding the port and intend -to follow the future RTEMS versions. I will do my best to provide -whatever support I can afford time-wise. - -Installation ------------- -Nothing unique to the MVME162. It has been incorporated into the -standard release. - -Port Description ----------------- -The port was done using already existing ports to the M68020 boards, -DMV152 and MVME136. - -The host system was SUN/Solaris 2.3, and the cross-development -environment consisted of Free Software Foundation (FSF)'s GNU C -compiler (version 2.6), GNU Assembler (version 2.3) and GNU binary -utilities binutils version 2.5.2, built with m68k as a target. The -recent/latest versions of other GNU programs (flex, make, etc) were -also used at the build stage. - -In all subdirectories of the RTEMS distribution tree, the directories -mvme136 were duplicated as mvme162. - -Essential modifications are detailed below: - -- the MVME162-specific hardware registers were described in bsp.h - -- timer and clock routines were made to use the MVME162's Tick Timers 1 -and 2, respectively - -- shared memory support was replaced by stubs for the time being - -- console IO was lifted entirely from the DMV152 support code, thanks -to the fact that Z8530 SCC used in DMV152 is upwards compatible with -the Z85230 SCC of the MVME162. (Only the memory mapping of the SCC -registers had to be changed.) - -- symbols in several *.s files were prepended with underscores to -comply with the xgcc configuration used (it prepends underscores to all -symbols defined in c code) - -- linkcmds file was modified to place the linked code into the memory -configured for the board in use - -- bspstart.c was modified as follows: - - monitors_vector_table = (m68k_isr *)0xFFE00000; - -was made to point to the power-up location of MVME162 interrupt vector -table. - -- The shutdown is a temporary solution. To exit cleanly, it has to disable -all enabled interrupts and restore the board to its power-up status. -Presently this is not done satisfactorily, as a result, the board needs -a hardware reset from the external VMEbus master or from the front -panel to ensure correct operation for subsequent downloads. - -Host System ------------ -The VMEbus master used to externally control and download the MVME162 -is a FORCE CPU-2CE board running Solaris 2.3. A simple program to load -s-records and start/reset the MVME162 was written. The code is in the -file tools/sload.c - -This code depends on the external VMEbus master's vme driver and is -provided as an example, without the Makefile. The bulk of the program -which parses the s-records is courtesy of Kym Newbery, -(8918927y@lux.levels.unisa.edu.au). - -In general, apart from x-gcc, the tools most often used while building -RTEMS for MVME162 were: find, grep, diff, and, of course - -MVME162 Embedded Controller Programmer's Reference Guide, -Motorola, MVME162PG/D1. - -Thanks ------- -- to On-Line Applications Research Corporation (OAR) for developing -RTEMS and making it available on a Technology Transfer basis; -- to Joel Sherril, the leader of the RTEMS development group for -stimulating and helpful discussions; -- to Kym Newbery (8918927y@lux.levels.unisa.edu.au) for his s-record -parser; -- to Gerd Truschinski (gt@first.gmd.de) for creating and running the -crossgcc mailing list -- to FSF and Cygnus Support for great free software; - - -+----------------------------------+-------------------------------+ -| Dr. Mikhail (Misha) Savitski | Voice : +46-980-79162 | -| Software Systems Engineer | Fax : +46-980-79161 | -| EISCAT Svalbard Radar Project | E-mail: mms@eiscathq.irf.se | -| EISCAT Scientific Association |----------- /\_/\ -----------| -| Box 812 S-98128 Kiruna, Sweden | EIS { o o } CAT | -+----------------------------------+-------oQQQ--(>I<)--QQQo-------+ - - |
