PyCortexMDebug
|
||||
==============
|
||||
|
||||
*A set of GDB/Python-based utilities to make life debugging ARM Cortex-M processors a bit easier*
|
||||
|
||||
It will consist of several modules which will hopefully become integrated as they evolve. Presently, there is only one:
|
||||
|
||||
## SVD
|
||||
ARM defines an SVD (System View Description) file format in its CMSIS
|
||||
standard as a means for Cortex-M-based chip manufacturers to provide a
|
||||
common description of peripherals, registers, and register fields. You
|
||||
can download SVD files for different manufacturers
|
||||
[here](http://www.arm.com/products/processors/cortex-m/cortex-microcontroller-software-interface-standard.php).
|
||||
|
||||
My implementation so far has only tested STM32 chips but should hold for others. If others are like those from ST,
|
||||
expect plenty of errors in the file. Like GPIOA having a register named GPIOB_OSPEEDR and lots of 16-bit registers
|
||||
that are listed as 32!
|
||||
|
||||
The implementation consists of two components -- An xml parser module (pysvd) and a GDB file (gdb_svd).
|
||||
I haven't yet worked out a perfect workflow for this, though it's quite easy to use when
|
||||
you already tend to have a GDB initialization file for starting up OpenOCD and the like.
|
||||
However your workflow works, just make sure to, in GDB:
|
||||
|
||||
source gdb_svd.py
|
||||
svd_load [your_svd_file].svd
|
||||
|
||||
These files can be huge so it might take a second or two. Anyways, after that, you can do
|
||||
|
||||
svd
|
||||
|
||||
to list available peripherals with descriptions. Or you can do
|
||||
|
||||
svd [some_peripheral_name]
|
||||
|
||||
to see all of the registers (with their values) for a given peripheral. For more details, run
|
||||
|
||||
svd [some_peripheral_name] [some_register_name]
|
||||
|
||||
to see all of the field values with descriptions.
|
||||
|
||||
You can add format modifiers like:
|
||||
|
||||
* `svd/x` will display values in hex
|
||||
* `svd/o` will display values in octal
|
||||
* `svd/t` or `svd/b` will display values in binary
|
||||
* `svd/a` will display values in hex and try to resolve symbols from the values
|
||||
|
||||
All field values are displayed at the correct lengths as provided by the SVD files.
|
||||
Also, tab completion exists for nearly everything! When in doubt, run `svd help`.
|
||||
|
||||
### TODO
|
||||
|
||||
Enable writing to registers and individual fields
|
||||
|
||||
### Bugs
|
||||
|
||||
There are probably a few. All planning, writing, and testing of this was done in an afternoon. There may be
|
||||
some oddities in working with non-STM32 parts. I'll play with this when I start working with other
|
||||
controllers again. If something's giving you trouble, describe the problem and it shall be fixed.
|
||||
|
||||
## DWT
|
||||
The ARM Data Watchpoint and Trace Unit (DWT) offers data watchpoints and a series of gated cycle counters. For now,
|
||||
I only support the raw cycle counter but facilities are in place to make use of others. As this is independent of the
|
||||
specific device under test, commands are simple and you can configure a clock speed to get real time values from
|
||||
counters.
|
||||
|
||||
dwt configclk 48000000
|
||||
|
||||
will set the current core clock speed. Then
|
||||
|
||||
dwt cyccnt reset
|
||||
dwt cyccnt enable
|
||||
|
||||
will reset and start the cycle counter. At any point
|
||||
|
||||
dwt cycnt
|
||||
|
||||
will then indicate the number of cycles and amount of time that has passed.
|
||||
|
||||
## ITM/ETM support
|
||||
|
||||
This is not implemented yet. I want to have more complete support for some of the nicer debug and trace features
|
||||
on Cortex-M processors. Parts of this will probably be dependent on OpenOCD and possibly on specific interfaces.
|
||||
I'll try to avoid this where possible but can't make any promises.

"""Parse the given XML input and convert it into a dictionary.
|
||||
|
||||
`xml_input` can either be a `string`, a file-like object, or a generator of strings.
|
||||
|
||||
If `xml_attribs` is `True`, element attributes are put in the dictionary
|
||||
among regular child elements, using `@` as a prefix to avoid collisions. If
|
||||
set to `False`, they are just ignored.
|
||||
|
||||
Simple example::
|
||||
|
||||
>>> import xmltodict
|
||||
>>> doc = xmltodict.parse(\"\"\"
|
||||
... <a prop="x">
|
||||
... <b>1</b>
|
||||
... <b>2</b>
|
||||
... </a>
|
||||
... \"\"\")
|
||||
>>> doc['a']['@prop']
|
||||
u'x'
|
||||
>>> doc['a']['b']
|
||||
[u'1', u'2']
|
||||
|
||||
If `item_depth` is `0`, the function returns a dictionary for the root
|
||||
element (default behavior). Otherwise, it calls `item_callback` every time
|
||||
an item at the specified depth is found and returns `None` in the end
|
||||
(streaming mode).
|
||||
|
||||
The callback function receives two parameters: the `path` from the document
|
||||
root to the item (name-attribs pairs), and the `item` (dict). If the
|
||||
callback's return value is false-ish, parsing will be stopped with the
|
||||
:class:`ParsingInterrupted` exception.
|
||||
|
||||
Streaming example::
|
||||
|
||||
>>> def handle(path, item):
|
||||
... print('path:%s item:%s' % (path, item))
|
||||
... return True
|
||||
...
|
||||
>>> xmltodict.parse(\"\"\"
|
||||
... <a prop="x">
|
||||
... <b>1</b>
|
||||
... <b>2</b>
|
||||
... </a>\"\"\", item_depth=2, item_callback=handle)
|
||||
path:[(u'a', {u'prop': u'x'}), (u'b', None)] item:1
|
||||
path:[(u'a', {u'prop': u'x'}), (u'b', None)] item:2
|
||||
|
||||
The optional argument `postprocessor` is a function that takes `path`,
|
||||
`key` and `value` as positional arguments and returns a new `(key, value)`
|
||||
pair where both `key` and `value` may have changed. Usage example::
|
||||
|
||||
>>> def postprocessor(path, key, value):
|
||||
... try:
|
||||
... return key + ':int', int(value)
|
||||
... except (ValueError, TypeError):
|
||||
... return key, value
|
||||
>>> xmltodict.parse('<a><b>1</b><b>2</b><b>x</b></a>',
|
||||
... postprocessor=postprocessor)
|
||||
ObjectDict([(u'a', ObjectDict([(u'b:int', [1, 2]), (u'b', u'x')]))])
|
||||
|
||||
You can pass an alternate version of `expat` (such as `defusedexpat`) by
|
||||
using the `expat` parameter. E.g:
|
||||
|
||||
>>> import defusedexpat
|
||||
>>> xmltodict.parse('<a>hello</a>', expat=defusedexpat.pyexpat)
|
||||
ObjectDict([(u'a', u'hello')])
|
||||
|
||||
You can use the force_list argument to force lists to be created even
|
||||
when there is only a single child of a given level of hierarchy. The
|
||||
force_list argument is a tuple of keys. If the key for a given level
|
||||
of hierarchy is in the force_list argument, that level of hierarchy
|
||||
will have a list as a child (even if there is only one sub-element).
|
||||
The index_keys operation takes precedence over this. This is applied
|
||||
after any user-supplied postprocessor has already run.
|
||||
|
||||
For example, given this input:
|
||||
<servers>
|
||||
<server>
|
||||
<name>host1</name>
|
||||
<os>Linux</os>
|
||||
<interfaces>
|
||||
<interface>
|
||||
<name>em0</name>
|
||||
<ip_address>10.0.0.1</ip_address>
|
||||
</interface>
|
||||
</interfaces>
|
||||
</server>
|
||||
</servers>
|
||||
|
||||
If called with force_list=('interface',), it will produce
|
||||
this dictionary:
|
||||
{'servers':
|
||||
{'server':
|
||||
{'name': 'host1',
|
||||
'os': 'Linux'},
|
||||
'interfaces':
|
||||
{'interface':
|
||||
[ {'name': 'em0', 'ip_address': '10.0.0.1' } ] } } }
|
||||
|
||||
`force_list` can also be a callable that receives `path`, `key` and
|
||||
`value`. This is helpful in cases where the logic that decides whether
|
||||
a list should be forced is more complex.
|
||||
|
||||
|
||||
If `process_comment` is `True` then comment will be added with comment_key
|
||||
(default=`'#comment'`) to then tag which contains comment
|
||||
|
||||
For example, given this input:
|
||||
<a>
|
||||
<b>
|
||||
<!-- b comment -->
|
||||
<c>
|
||||
<!-- c comment -->
|
||||
1
|
||||
</c>
|
||||
<d>2</d>
|
||||
</b>
|
||||
</a>
|
||||
|
||||
If called with process_comment=True, it will produce
|
||||
this dictionary:
|
||||
'a': {
|
||||
'b': {
|
||||
'#comment': 'b comment',
|
||||
'c': {
|
||||
|
||||
'#comment': 'c comment',
|
||||
'#text': '1',
|
||||
},
|
||||
'd': '2',

## SVD
|
||||
|
||||
ARM defines an SVD (System View Description) file format in its CMSIS standard as a means for Cortex-M-based chip manufacturers to provide a common description of peripherals, registers, and register fields. You can download SVD files for different manufacturers [here](http://www.arm.com/products/processors/cortex-m/cortex-microcontroller-software-interface-standard.php).
|
||||
|
||||
The implementation consists of two components -- An lxml-based parser module (pysvd) and a GDB file (gdb_svd). I haven't yet worked out a perfect workflow for this, though it's quite easy to use when you already tend to have a GDB initialization file for starting up OpenOCD and the like. However your workflow works, just make sure to, in GDB:
|
||||
|
||||
source gdb_svd.py
|
||||
svd_load [your_svd_file].svd
|
||||
|
||||
These files can be huge so it might take a second or two. Anyways, after that, you can do
|
||||
|
||||
svd
|
||||
|
||||
to list available peripherals with descriptions. Or you can do
|
||||
|
||||
svd [some_peripheral_name]
|
||||
|
||||
to see all of the registers (with their values) for a given peripheral. For more details, run
|
||||
|
||||
svd [some_peripheral_name] [some_register_name]
|
||||
|
||||
to see all of the field values with descriptions.
|
||||
|
||||
You can add format modifiers like:
|
||||
|
||||
* `svd/x` will display values in hex
|
||||
* `svd/o` will display values in octal
|
||||
* `svd/t` or `svd/b` will display values in binary
|
||||
* `svd/a` will display values in hex and try to resolve symbols from the values
|
||||
|
||||
All field values are displayed at the correct lengths as provided by the SVD files.
|
||||
Also, tab completion exists for nearly everything! When in doubt, run `svd help`.
