The resulting code obviously +contains bugs (know and unknown) and limitations. I assume no +responsibility for quality and support of the software in question. + +Now on more optimistic note: + +I have run most of the standard RTEMS sptests, and neither of them +failed. 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-------+ + + diff --git a/c/src/lib/libbsp/m68k/mvme162/clock/ckinit.c b/c/src/lib/libbsp/m68k/mvme162/clock/ckinit.c new file mode 100644 index 0000000000..95e35e5f66 --- /dev/null +++ b/c/src/lib/libbsp/m68k/mvme162/clock/ckinit.c @@ -0,0 +1,91 @@ +/* Clock_init() + * + * This routine initializes the Tick Timer 2 on the MVME162 board. + * The tick frequency is 1 millisecond. + * + * Input parameters: NONE + * + * Output parameters: NONE + * + * COPYRIGHT (c) 1989, 1990, 1991, 1992, 1993, 1994. + * On-Line Applications Research Corporation (OAR). + * All rights assigned to U.S. Government, 1994. + * + * This material may be reproduced by or for the U.S. Government pursuant + * to the copyright license under the clause at DFARS 252.227-7013.
