Add readline support to s51

2009-03-27T05:41:47+00:00

Have S51 ignore SIGINT while running under sdcdb.

2009-01-06T05:43:44+00:00

This prevents keyboard interrupts from accidentally stopping s51. Signed-off-by: Keith Packard

Use SFR access funcs. Support 'dump' command. Add -m (monitor) flag.

2008-12-28T08:11:13+00:00

Not all SFRs are visible in the unified address space, so the SFR-specific accessors are required. The dump command is the same as the various 'd*' commands, but also supports dumping program memory. The new -m (monitor) flag watches the command stream between s51 and sdcdb. Signed-off-by: Keith Packard

s51: get start address from ihx file. re-enable breakpoints after reset.

2008-12-27T19:25:58+00:00

Use the start of the ihx file when asked to run from 0x0, this lets sdcdb run programs from ram. The reset command clears all hw breakpoints, so reset them afterwards. Signed-off-by: Keith Packard

s51: add breakpoints and the ability to block awaiting a breakpoint.

Add preliminary version of s51, a UI clone of the 8051 emulator.

2008-12-22T07:33:42+00:00

sdcdb provides source-level debugging using the 8051 emulator, s51. By emulating that emulator a the UI level, we should be able to get source debugging right on our target platform. This is just the preliminary structure for the program with most commands not yet implemented.
