  • include/bsp.h (Clear_tm27_intr): Stop the timer and disable the interrupt. This was not quite right before and we were getting uncontrolled interrupt nesting in tm27.
  • timer/timer.c (Timer_Initialize): Added an extra reset and changed the ITMR register so we will never get an interrupt. (Read_timer): Fixed so the timer actually stops before it is read. Before some times reported were outraguously high.
  • start/start.S: Major clean including using stack in linkcmds, deleting unused code, and zeroing the BSS using the linkcmds information.
  • startup/linkcmds: Put heap in lower memory than workspace and move _clear_end so both are zeroed.
  • Property mode set to 100644

17
18        * include/bsp.h, timer/timer.c: Updated so timer appears to
19        work and support tm27.  I would prefer to time a software
20        interrupt rather than an use an extra timer though.
21
222001-01-09      Joel Sherrill <joel@OARcorp.com>
23
24        * clock/clockdrv.c: Clean up.
25        * include/bsp.h: Uncomment and fix set_vector() prototype.
26
272001-01-03      Joel Sherrill <joel@OARcorp.com>
28
29        * console/console-io.c: Removed unused variable initialized.
30
312001-01-03      Joel Sherrill <joel@OARcorp.com>
32
33        * clock/Makefile.am: Fixed reference to ckinit.c.
34        * clock/clockdrv.c: Enabled fast idle.
35        * console/console-io.c: Added console_initialize_hardware().
36

38
39        * timer: New subdirectory.
40        * timer/.cvsignore, timer/Makefile.am, timer/timer.c: New files.
41        * tools/ChangeLog: New file.
42
432000-12-19      Joel Sherrill <joel@OARcorp.com>
44
45        * Makefile.am: Added tools subdirectory and removed commented out line.
46        * configure.in: Added tools subdirectory.
47        * tools: New subdirectory.
48        * tools/.cvsignore, tools/Makefile.am, tools/configure.in,
49        tools/runtest: New files -- based on powerpc/psim.
50        * clock/clockdrv.c: Guessed new value for clock tick.  Need to
51        add fast idle support.
52        * include/bsp.h: tm27 support initiated.
53        * Most tests appear to run correctly!
54
552000-12-13      Joel Sherrill <joel@OARcorp.com>
56
57        * README: Updated.  We are now vectoring a clock tick ISR handler.
58        But RTEMS is not returning from the ISR properly.
59        * clock/clockdrv.c: Now causes interrupts but has not been calibrated.
60        * include/bsp.h: Use <libcpu/tx3904.h>
61        * startup/Makefile.am: Add setvec.c from shared.
62        * startup/bspstart.c: Initialize the status register (SR) so
63        no interrupts are masked but global interrupts (SR_IEC) are off.
64        Added call to install the ISR prologue code.
65        * wrapup/Makefile.am: Pick up more pieces from libcpu.
66
672000-12-11      Joel Sherrill <joel@OARcorp.com>
68
69        * startup/bspclean.c: New file to explicitly invoke _sys_exit().
70        * README: Updated.
71
722000-12-06      Joel Sherrill <joel@OARcorp.com>
73
74        * README: Updated to reflect status.
75        * startup/linkcmds: Added .ctor and .dtor sections to no avail.
76
772000-11-30      Joel Sherrill <joel@OARcorp.com>
78
79        * README: Updated to reflect current status.  Misaligned reference
80        during initialization may be compiler problem.
81        * console/console-io.c: Added support for printk().
82        * startup/linkcmds: Reserve 512K for RTEMS Workspace.
83
842000-11-27      Joel Sherrill <joel@OARcorp.com>
85
86        * startup/linkcmds: Fix typo and add extra 0 to base address.
87        Now runs until printf() tries to put a character and then
88        it locks up checking a status bit that does not change.
89

91
92        * The JMR BSP is for a Toshiba TX39 evaluation board but
93        can also be used with the mips simulator in gdb.
94        * .cvsignore, ChangeLog, Makefile.am, README, bsp_specs,
95        configure.in, clock/.cvsignore, clock/Makefile.am,
