1998-01-30Big patch form Ralf Corsepius described in this email:Joel Sherrill97-388/+194
Here is the result of my nightly work to get RTEMS_ROOT=$srcdir working with different shells and relative/absolute paths. What I did is relatively simple in principle: Instead of setting RTEMS_ROOT in and then let configure substitute @RTEMS_ROOT@ inside the Makefiles, I now let each Makefile set RTEMS_ROOT from each Makefile's @top_srcdir@ value. The difference is subtile, but with enormous side effects: - If RTEMS_ROOT is set in configure, then the same single value will be propagated to all Makefiles. This breaks using relative paths, as the relative path to the root of the source tree is used inside of all subdirectory Makefiles. - Now each sets RTEMS_ROOT = @top_srcdir@. top_srcdir is computed individually by configure for each single, hereby receiving the correct value, no matter if relative or absolute paths are used. To get this working, I needed to remove setting RTEMS_ROOT from, because this overrides the value of RTEMS_ROOT from each individual Makefile. Furthermore, I removed RTEMS_CUSTOM from the Makefiles and replaced all "include $(RTEMS_CUSTOM)" directives with"include $(RTEMS_ROOT)/make/custom/$(RTEMS_BSP)". Perhaps you don't like this, but I think, to have one variable less is clearer and easier to understand than having several variables refering to the next one. I enclose a small patch to this mail, which - fixes the config.h problem (to finally clearify misunderstands) - removes assignment/subsitution of RTEMS_ROOT from - contains a workaround for the application Makefile's RTEMS_ROOT problem (reported by Eric) - removes some unused lines from the toplevel - removes assignment of RTEMS_ROOT from make/

I try to keep w\up with it. Now that you have asked -- I'll attach a list of files lacking an RCS-Id to this mail. This list has been generated by a little sh-script I'll also enclose.

1997-12-22Fixes from Eric Norum. C++ support added in previous version was broken:Joel Sherrill3-291/+272
1) In my haste to add C++ constructor/destructors to the 68360 linkcmds scripts I managed to break all existing 68360 programs. Linker scripts which actually produce a working executable are contained below. The problem was that the constructor/destructors weren't included before the etext symbol. On top of that Eric and I appear to have problems with attachments: 2) In deciphering the above problem I think I stumbled across the reason you've had with patches mailed from me. I noticed that the linkcmds (and linkcmds.bootp) scripts in the latest distribution have a control-M (carriage return) at the end of each line. Could you check the files below before installing them in the distribution and see that there aren't returns in the files? Maybe if I send everything as a tar attatchment things will work better.

1997-12-20Moved -qnolinkcmds option so arguments passed on the command line areJoel Sherrill11-22/+22
interpreted at the right point per Eric Norum's discovery: The problem with the my previous `fix' for adding linker commands was with the ordering of the options to the linker. For example, to make a larger heap size, the application Makefile would CFLAGS_LD = -Wl,--defsym -Wl,HeapSize=0x40000 The command passed to the linker would be : m68k-rtems-ld .... -T xxx/linkcmds .... --defsym HeapSize=0x40000 ..... This doesn't work because the script in linkcmds inserts a default value for HeapSize if HeapSize is not defined by the time the linker looks at the linkcmds script. The solution seems to be to move the -T linkcmds%s in the bsp_specs file out of the link specfication and into the lib specification -- a little unorthodox, perhaps, but it seems to work!

1997-09-18Merged changes from Eric Norum:Joel Sherrill3-16/+32
Enable 68360 watchdog. The watchdog control register is a `write-once' register, so the watchdog has to be enabled in the boot roms if it is to be used at all. To make the change transparent I added a default feed of the watchdog to the clock interrupt handler. This can be overridden if the application wants to handle the watchdog. The only difficulty with this change is that an application has to either include the clock driver or handle the watchdog explicitely. I don't think this is much of a problem since I am pretty sure that almost every application includes the clock driver.

1997-09-03Fix from Eric Norum. Here is the comment:Joel Sherrill1-2/+2
Enable SDMA operation during FREEZE. It seems that disabling SDMA during freeze makes the SMC channels work erratically.

1997-08-22start no longer a global symbol per Eric Norum's request.Joel Sherrill2-2/+12
Also, I ran across a nasty problem the first time I tried downloading and running an application compiled with the new snapshot. To make a very long story short, the `start' in ...../m68k/gen6860/start360/start360.s must not be global. The change is simple -- just remove the .globl start from start360.s.
