|
2001-04-24 Jonathan Larmour
|
| 15 |
|
|
|
| 16 |
|
|
* src/vectors.S: Support daft platforms like the CEB which have
|
| 17 |
|
|
default on-chip flash that vector NMI to 2 insns after reset.
|
| 18 |
|
|
Also place hal_v85x_ice_syscall_info in fixed location, only
|
| 19 |
|
|
for ROM/ROMRAM builds.

|
|
|
| 23 |
|
|
* src/vectors.S: Overhaul...
|
| 24 |
|

|
Pass in correct argument to exception_handler
|
| 28 |

|
| 29 |
|
|
Add __allow_nmi as a somewhat kludgy means of determining
|
| 30 |
|
|
whether NMIs should be ignored - important if the board resets
|
| 31 |
|
|
and the vector tables are temporarily inconsistent.
|
| 32 |
|
|
Initialize __vsr_table statically.
|
| 33 |
|
|
Add some generic elements of ICE debugging support
|
| 34 |
|

|
|
|
| 37 |
|
|
* src/hal_mk_defs.c (main): Update to reflect new vector names
|
| 38 |

(to match official NEC docs)
|
| 39 |
|
|
|
| 40 |
|

|
* include/hal_arch.h: Remove obsolete comment reference to arch.inc.
|
| 45 |
|
|
|
| 46 |
|
|

|
| 47 |
|
|
* include/hal_io.h: Ditto.

|
| 49 |
|
|
|
| 50 |
|
|
* cdl/hal_v85x.cdl: Move CYGHWR_HAL_V85X_CPU_FREQ into platforms
|
| 51 |
|
|
(and make Hz, not MHz).
|
| 52 |
|
|

|
| 62 |
|
|
|
| 63 |
|
|
2001-01-18 Nick Garnett
|
| 64 |
|
|
|
| 65 |
|
|
* src/vectors.S: Added underscore to reference to
|
| 66 |
|
|
cyg_scheduler_sched_lock, since CYGBLD_ATTRIB_ASM_ALIAS() now adds
|
| 67 |
|
|
one automatically.
|
| 68 |
|
|
|
| 69 |
|

|
2000-10-09 Gary Thomas
|
| 79 |
|
|
|
| 80 |
|
|
* src/vectors.S (start): Need to handle ^C for all applications.
|
| 81 |
|
|
|
| 82 |
|
|
2000-09-13 Jonathan Larmour
|
| 83 |
|
|
|
| 84 |
|
|
* src/vectors.S: When calling C functions, ensure there is 16 bytes
|
| 85 |
|
|
space for the parameter flushback area (as per the calling convention)
|
| 86 |
|
|
on the stack
|
| 87 |
|
|
|
| 88 |
|
|
2000-09-07 Jonathan Larmour
|
| 89 |
|
|
|
| 90 |
|
|
* include/basetype.h: Don't need special alignment after all - it was
|
| 91 |
|
|
a bug elsewhere.
|
| 92 |
|
|
|
| 93 |
|
|
2000-09-06 Gary Thomas
|
| 94 |
|
|
|
| 95 |
|
|
* include/basetype.h: Need special alignment to match the way
|
| 96 |
|
|
the compiler/linker actually do things.
|
| 97 |
|
|
|
| 98 |
|
|
* cdl/hal_v85x.cdl: Improve variant handling and specification.
|
| 99 |
|
|
|
| 100 |
|
|
2000-08-30 Gary Thomas
|
| 101 |
|
|
|
| 102 |
|
|
* src/vectors.S (start): Allow programs to field NMI exceptions.
|
| 103 |
|
|
|
| 104 |
|
|
2000-07-24 Jonathan Larmour
|
| 105 |
|
|
|
| 106 |
|
|

|
| 107 |
|
|
|
| 108 |
|
|
* src/v85x.ld: Switched to new table definition mechanism.
|
| 109 |

|
|
|
| 112 |
|
|
* src/vectors.S (_hal_plf_reset_board): Needs to be defined in all

| 115 |
|
|
2000-06-27 Jesper Skov

|
| 124 |
|
|
2000-06-15 Gary Thomas

|
| 128 |
|
|
* src/hal_misc.c (hal_default_isr): Update for new debug

| 135 |
|
|
2000-06-12 Gary Thomas
|
| 136 |
|
|
|
| 137 |
|
|
* src/vectors.S (return_from_exception_or_interrupt): Revert
|
| 138 |
|
|
reorg change (05-26) which broke GDB breakpoints.
|
| 139 |
|
|
|
| 140 |
|
|
2000-06-08 Jesper Skov
|
| 141 |

| 153 |
|
|
2000-05-25 Gary Thomas
|
| 154 |
|
|
|
| 155 |
|
|
* src/vectors.S: Handle different chips (number of interrupt
|
| 156 |
|
|
sources differs, exception table is altered, etc).
|
| 157 |
|
|
|
| 158 |
|
|
* include/hal_intr.h: Actual interrupt layout now defined by
|
| 159 |
|
|
variant/platform since these differ depending on the chip.
|
| 160 |
|
|
|
| 161 |
|
|
2000-05-03 Gary Thomas
|
| 162 |

|
| 164 |
|
|
|
| 165 |
|
|
2000-04-14 Gary Thomas
|
| 166 |
|
|
|
| 167 |
|
|
* src/hal_misc.c (exception_handler): Proper handling of nested
|
| 168 |
|
|
[watchdog] interrupts - don't corrupt GDB registers.
|
| 169 |
|
|
|
| 170 |
|
|
* src/hal_mk_defs.c: Add some symbols required for NMI handling.
|
| 171 |
|
|
|
| 172 |
|
|
* src/vectors.S (return_from_exception_or_interrupt):
|
| 173 |
|
|
Properly handle different cases for exception, NMI and ISR.
|
| 174 |
|
|
|
| 175 |
|
|
* include/hal_intr.h (HAL_TRANSLATE_VECTOR): Ignore interrupt
|
| 176 |
|
|
chaining - doesn't happen on this hardware.
|
| 177 |
|
|
|
| 178 |
|
|
2000-04-11 Gary Thomas
|
| 179 |
|
|
|
| 180 |
|
|
* src/vectors.S (exception): Handle NMI. In particular, need to
|
| 181 |
|
|
have appropriate bits set so they clear and also get the state
|
| 182 |
|
|
from the proper save registers.
|
| 183 |
|
|
(exception): Register save was wrong - ROM only.
|
| 184 |
|
|
|
| 185 |
|
|
2000-03-31 Gary Thomas
|
| 186 |
|
|
|
| 187 |
|
|
* src/hal_mk_defs.c: Add definition for 'ep' register.
|
| 188 |
|
|
|
| 189 |
|
|
* include/hal_intr.h:
|
| 190 |
|
|
* cdl/hal_nec.cdl: Add config option to choose between inline and
|
| 191 |
|
|
real functions for interrupt macros.
|
| 192 |
|
|
|
| 193 |
|
|
* src/vectors.S: Tune up - use SLD/SST for smaller, faster code
|
| 194 |
|
|
in context load/save routines. Also remove IRQ trace/debug code.
|
| 195 |
|
|
|
| 196 |
|
|
2000-03-30 Gary Thomas
|
| 197 |
|
|
|
| 198 |
|
|
* src/vectors.S (do_interrupt): Can't use R13 across function calls.
|
| 199 |
|
|
This caused instability when turning on kernel instrumentation.
|
| 200 |
|
|
|
| 201 |
|
|
* include/hal_intr.h: Use out-of-line code for interrupt functions
|
| 202 |
|
|
for tracing/testing.
|
| 203 |
|
|
|
| 204 |
|
|
* src/vectors.S: Working support for separate interrupt stack.
|
| 205 |
|
|
Some debug/trace code left in.
|
| 206 |
|
|
|
| 207 |
|
|
* src/hal_mk_defs.c:
|
| 208 |
|
|
* include/hal_arch.h: Documented API does not match actual GCC
|
| 209 |
|
|
register usage. Need to save R1/R2/R4/R5 for setjmp/longjmp.
|
| 210 |
|
|
|
| 211 |
|
|
2000-03-27 Gary Thomas
|
| 212 |
|
|
|
| 213 |
|
|
* src/vectors.S (do_interrupt): Pass regs to ISR & DSR.
|
| 214 |
|
|
|
| 215 |
|
|
* include/basetype.h: Endian-ness was incorrect.
|
| 216 |
|
|
|
| 217 |
|
|
* include/hal_arch.h:
|
| 218 |
|
|
* src/hal_mk_defs.c: Complete setjmp/longjmp support.
|
| 219 |
|
|
|
| 220 |
|
|
* src/vectors.S: Add interrupt stack.
|
| 221 |
|
|
|
| 222 |
|
|
2000-03-21 Gary Thomas
|
| 223 |
|
|
|
| 224 |
|
|
* src/vectors.S (_hal_plf_reset_board): Add board reset function.
|
| 225 |
|
|
|
| 226 |
|
|
* include/hal_arch.h (CYGHWR_TEST_PROGRAM_EXIT): Define RESET for ROM
|
| 227 |
|
|
based programs.
