- protocol now correctly reports SWO and SWCLK clock rates on set
- remove some debug printfs that were causing fw hangs (investigate later)
- allow setting a 1MHz SWCLK rate
- CMD_ATTACH now supports an argument to select one of several special
reset or escape sequences:
ATTACH_SWD_RESET: 60 HI, 4 LO, basic line reset
ATTACH_JTAG_SWD: escape sequence for JTAG -> SWD mode switch
ATTACH_DORMANT_TO_SWD: escape squence to exit dormant mode
ATTACH_SWD_TO_DORMANT: and go back again
- add special support for writing to DP TARGETSEL register
(response phase must be ignored), needed for SWD multidrop support
- bump protocol version to 1.3
- bump firmware version to 1.0 (it's long overdue)
The original tooling is lost to the mists of time and long-discarded
workstations, but this generates identical results and will enable
updating the code on the m0 sub-processor going forward. Yay.
The xxd tool generates two spaces of indent, not four.
Fix this existing file to match the tool output to make it easier
to detect changes to the resulting image header when rebuilt.
Mostly just a few warnings where things are promoted via passing floats to
printf. Those we should generally remove anyway because they're just
benchmarking code. Most things LK runs on either doesn't have float or
doesn't have double sized floats.
Some of the structures, notably 'cmd', in the lib console stuff are a
little too generically named and have collided with some other code
so prefix the names a bit more cleanly with console_
The change is largely mechanical, and folks with out of tree code can
easily switch by renaming:
cmd -> console_cmd
cmd_args -> console_cmd_args
cmd_block -> console_cmd_block
console_cmd -> console_cmd_func
Apologies if this breaks you but it should be pretty easy to fix.
No need to malloc this memory if it's always going to be initialized
anyway. Add history disabling switch to a few targets to make sure both
builds are tested.
This lets some arches return a 64bit counter.
As a result of fixing this, removed -Wno-format switch in the test app
which caused the need to fix a lot of printfs.
Now you need to include arch/atomic.h to get to the atomic routines.
This simplifies a recusion issue in the way arch/ops.h included
arch_ops. Also just generally makes things cleaner.
TL;DR most uses of lib/console.h -> lk/console_cmd.h
Move the part that lets a piece of code somewhere in the system to
define a console command from the actual lib/console api to start an
instance of the console. Move in almost every place the user of the
console command definition to the new header, lk/console_cmd.h which is
always in the include path.
Also remove most uses of testing for WITH_LIB_CONSOLE since you can
almost always just safely define it and then let the linker remove it.
Examples are include/platform.h -> platform/include/platform.h
include/target.h -> target/include/target.h
The old model generally considered these to be Always There includes,
but they're starting to stick out more and more so may as well actually
follow the model that most of the rest of the system follows.
Almost nothing changes here except moving braces to the same line as the
function declaration. Everything else is largely whitespace changes and
a few dangling files with tab indents.
See scripts/codestyle
Currently targets qemu's sifive_e machine, which is a split flash/ram
machine, much like the Sifive HiFive1. Untested as of yet on a real
HiFive1.
Basic support including interrupts and architectural timers in place.
Most of the warnings are new, such as needing to mark fallthroughs on
cases explicitly. A few are based on signed vs unsigned comparisons.
Disable one warning that was annoying about comparing null to arguments
marked nonnull.
Previously, if tail was == 0, and we wrote exactly enough bytes to
the end of the buffer, then head would end up at 0 as well. This
would make the buffer instaneously empty, as head == tail.
NDebug sits and waits for a reset message before becoming active. I intend to
use this handshake for the system debug protocol as well as the high level
protocol so I'm pulling the logic for it up into the core ndebug utility
functions.
Ran everything through scripts/codestyle.space, which uses astyle
to generally follow K&R style.
Biggest non whitespace change is pulling brackets down on function
declarations, which I'm pretty ambivalent about, but astyle insists
on taking a stance
