* Add full gdb support with uart/Serial integration
* Fix GDB merge errors
* Update to unpatched GDB protocol specification
It appears that Espressif patched the open source xtensa GDB port in
order to build their old GDB executable and their old gdbstub (basically
removing any register in a generic xtensa and only leaving those
present in the chip they synthesized). Their GDBStub also assumed this
behavior.
Unpatched upstream GNU GDB now expects all the registers in
xtensa-config.c to be sent/read on a 'g' command. Change the GDB stub
to send "xxxxxxxx"s (legal per the spec) for unimplemented registers.
This makes the 'g' response much longer, but it's results are cached
and in an interactive debugger it isn't noticeable.
* Fix .iram.literal to come before .iram.text for GDB
* Move functions to flash, call using wrappers
All functions which are not interrupt or exception called are now in
flash. A small IRAM wrapper enables flash when processing main GDB ops
by calling Cache_Read_Enable_New() and then jumping to the main flash
code. This seems to work for catching exceptions, data and code breaks,
and Ctrl-C.
The UART ISR handler and exception handler register-saving bits of
code in ASM are still in IRAM.
GDB IRAM usage is now about 670 bytes.
* Remove LWIP2 builder commit
* Add documentation and gdbstub_init header
Add some simple GDB documentation to the main tree showing a worked
example.
Adds the definition of `void gdbstub_init()` to <GDBStub.h>
* Clean up GDB include and library dir
Replace GDBstub.h with the version in the internal/ directory, and
adjust stub code accordingly. This way, only one copy of a file called
"GDBstub.h" will exist.
Update the gdbcommands and replace the obsolete ESPRESSIF readme with
@kylefleming's version since we're mainly doing serial, not TCP,
connected debugging.
Bump the library rev. number since this is a pretty big functionality
change.
Minor documentation tweak.
* Undo much of UART refactoring, set fifo IRQ to 16
Remove the refactoring of pin control and other little things not directly
related to GDB processing. Should greatly reduce the diff size in uart.c.
Should also remove any register value changes (intended or otherwise)
introduced in the original PR from @kylefleming.
Set the FIFO interrupt to 16 chars when in GDB mode, matching the latest
UART configuration for highest speed.
* Add architecture comments, cleanup uart.c code
Comments added to UART.c trying to explain (as best as I understand it)
the changes done to support GDB and how they interact with standard
operation.
Fix the uart_uninit to stop the ISR and then free appropriately.
Fix uart_isr_handle_data (GDB's shim for sending chars to the 8266 app)
to do the exact same thing as the standard UART handler including set
the overflow properly and either discard or overwrite in that case.
Fix serial reception when GDB enabled by enabling the user recv ISR.
Remove commented attributes from gdbstub, leftover from the move to
flash.
General logic cleanup per comments in the PR.
* Also set the UART flags for HW error in GDB
Ensure we also check the UART flags and set the uart status
appropriately when in GDB mode.
* Add fix for SoftwareSerial submodule errors to documentation
* Update installing.rst
Replaces and based on #5602Fixes#5583
* Update installing.rst
Remove forgotten section
Add update section for Other OS
Using a pluggable architecture, allow updates delivered via the Update
class to be verified as signed by a certificate. By using plugins, avoid
pulling either axTLS or BearSSL into normal builds.
A signature is appended to a binary image, followed by the size of the
signature as a 32-bit int. The updater takes a verification function
and checks this signature using whatever method it chooses, and if it
fails the update is not applied.
A SHA256 hash class is presently implemented for the signing hash (since
MD5 is a busted algorithm).
A BearSSLPublicKey based verifier is implemented for RSA keys. The
application only needs the Public Key, while to sign you can use
OpenSSL and your private key (which should never leave your control
or be deployed on any endpoints).
An example using automatic signing is included.
Update the docs to show the signing steps and how to use it in the
automatic and manual modes.
Also remove one debugging line from the signing tool.
Saves ~600 bytes when in debug mode by moving strings to PMEM
Windows can't run the signing script, nor does it normally have OpenSSL
installed. When trying to build an automatically signed binary, warn
and don't run the python.
Fix link to WiFiEvents
Add note about WiFiClients and WiFiServers going down when a WiFi interface goes down, and that it's the user's responsibility to bring them back up.
BearSSLX509List, BearSSLSession, BearSSLPublicKey, and BearSSLPrivateKey
were all in the global namespace and not in the BearSSL:: one, due to an
oversight when they were originally created. Move them to the proper
namespace with the following mapping:
BearSSLX509List => BearSSL::X509List
BearSSLSession => BearSSL::Session
BearSSLPublicKey => BearSSL::PublicKey
BearSSLPrivateKey => BearSSL::PrivateKey
* Update debugging.rst
PLEASE REVIEW
The current link definitely points to the wrong line, where there's nothing remotely resembling a list of DEBUG_ESP_* definitions. There's not an actual "full list" in the whole boards.txt really, but this is the closest thing that can be found in that file.
Some additional explanation is needed though, unless there is an actual list somewhere else.

Sphinx 1.8.0 seems to always fail to build the docs due to interactions
with doctest.py. This means no CI builds can pass and no new PRs can be
applied.
Fix the version at 1.7.9 for now until the dependencies get updated to with 1.8.
The error seen is:
File "/home/travis/.local/lib/python2.7/site-packages/sphinx/highlighting.py", line 26, in <module>
from sphinx.ext import doctest
SyntaxError: unqualified exec is not allowed in function 'run' it contains a nested function with free variables (doctest.py, line 97)
The full traceback has been saved in /tmp/sphinx-err-e8JyUQ.log, if you want to report the issue to the developers.
Please also report this if it was a user error, so that a better error message can be provided next time.
A bug report can be filed in the tracker at <https://github.com/sphinx-doc/sphinx/issues>. Thanks!
* Add information about the max_connection constructor argument.
* Correct information about max soft-AP connections.
* Add information about what happens when max_connection is reached.
* Correct terminology
* - Correct the valid range of max_connection to 1 - 8.
- Include reference.
* Analog input voltage can be 3.3V
According to this tutorial and my personal test with my Amica, 1.0V delivers 320 and 3.3V delivers 1024 at 10-bit resolution. I guess 3.3V is possible.
