Also, some small fixes and additional debug code/output.
|
|
As per guidelines in HACKING, the protocol "commands"/items should be ALLCAPS,
thus change 'data' to 'DATA'. Also, fix MX25Lxx05D protocol decoder
accordingly, currently the only one we have which stacks on top of SPI.
Add a new 'CS-CHANGE' output protocol item, which is sent upon every
change of the CS# pin value (either 0->1, or vice versa). This is needed
by various higher-level PDs.

Add ACLOCAL_DIR setting and AM_PROG_AR macro for compiling with Homebrew
under Mac OS X.
Applies essentially the same change to
{libsigrok,libsigrokdecode,sigrok-cli}/{autogen.sh,configure.ac}
It may be that the same fix is needed for the other autogen.sh and/or
configure.ac files, but that hasn't been tested and therefore not in
this commit.

In the protocol decoder you always get all required probes, then _all_
optional probes in the list of probes in the decode() call.
Example:
(r1, r2, r3, o1, o2, o3, o4) = pins
In this case r1-r3 are required probes, o1-o4 are optional probes.
However, the value of valid/used/specified probes will be 0 or 1,
whereas the value of probes that were not specified/assigned by the user
will be (at the moment) 42.
The PD can check for a valid probe like this:
if p in (0, 1):
...
Or check for an invalid probe:
if (p > 1):
...
The value of 42 could change to be -1 or None later.

Also, fix minor consistency issues, cosmetics, typos.
|
|
Add APB-AP register offsets/names, refactor and fix some code, handle
in/out APACC/DPACC better.
|
|
Make it consistent with the rest of the code

Also, add a few code comments.

Add APACC register handling, fix DPACC handling (esp. 'A' register size),
ouput a warning upon reserved DAPABORT bits being non-zero, implement
preliminary state machine, add various TODOs.
This is still work in progress, not yet finished or working properly.

(not yet finished)
This protocol decoder can decode ST STM32 specific JTAG accesses, knows
about the STM32-specific registers and bits.

Don't handle them for now, will do this later.

Most importantly, both TDI and TDO are sampled at the rising TCK edge,
and only upon transitions from SHIFT-DR to SHIFT-DR and SHIFT-IR to SHIFT-IR
are we to save the TDI/TDO values (if I understood this correcly).
Also, start out in RUN-TEST/IDLE state for now. This is useful if you
have JTAG dumps which start "in the middle" somewhere, not in the
TEST-LOGIC-RESET state. For full dumps, the JTAG software usually issues
five TMS=1 cycles to force the JTAG state machine into TEST-LOGIC-RESET
anyway, so this works fine too.

This is unfinished, needs some more work.

Not quite finished yet, but relatively close.
|

This is unfinished and not tested, and probably not really working, yet.

This avoids warnings on a MinGW build. The feature depends on ELF files,
but MinGW/Windows uses PE files.

No need to use the LIBSIGROKDECODE_ prefix here when we use SRD_ everywhere
else. Also, better distinction between package version and lib version.

We'll have a libsigrok and a libsigrokdecode release soon. After that,
any API changes must be properly documented and reflected in the
SO version (and package version) numbers of the libs.

The i2cdemux protocol decoder is the more generic version of the
obsolete ebr30a_i2c_demux decoder, and should be able (now or later) to do
everything that ebr30a_i2c_demux can do.
